Marx's evaluation of a social system or social phenomenon mainly has two scales: one is the historical scale and the other is the moral scale. The so-called historical scale is based on whether it conforms to objective laws and historical inevitability, whether it conforms to the interests of the overwhelming majority of people and whether it is conducive to the development of all mankind. The so-called moral scale refers to judging the existence, right and wrong and size of a thing's value with certain moral norms and concepts as standards. Historical scale and moral scale are the basic ways for human beings to understand and grasp the world, and they are also the embodiment of human subject spirit. Human beings use double scales to transform history and reality, thus promoting social progress and people's all-round development. Therefore, starting from the ultimate goal of all-round and free development of mankind, these two scales are consistent. However, in real life, these two scales often show antinomy. "This essential consistency and betrayal in reality require us to consciously use dialectical thinking and adhere to the unity of historical scale and moral scale when evaluating a social phenomenon."
The consumption problem is everywhere, which is closely related to human life. No matter in the past, present or future, human beings are inseparable from the satisfaction and consumption of material and cultural needs. But consumerism has never existed, and it is only the product of social development to a certain historical stage. Since modern times, with the development of science and technology in western countries, material production has increased geometrically, and social production is relatively surplus, which requires consumption to maintain, stimulate and stimulate the further development of production. People gradually ended the society centered on "production" and entered the era centered on "consumption". At this time, the purpose nature of people's consumption leaps above the means nature, and consumption is no longer a simple economic behavior, but has become a lifestyle and cultural behavior. At this time, consumerism came into being. French sociologist Baudrillard defined consumerism in his book Consumer Society, that is, the purpose of consumption is not to meet the actual needs, but to constantly pursue the satisfaction of the desires created and stimulated.
First, the basic concept of consumerism
"Many years ago, if a person was uncomfortable and didn't know what to do, he might go to church, have a revolution, and so on. Today, if you feel uncomfortable and at a loss, how can you get rid of it? Go and spend! " In the view of consumerism, people are consumers, and the value of life lies in the creation and profligacy of wealth. There is no other choice. People confirm the creed of "I consume, therefore I am" in endless consumption, and strengthen their belief in this creed through consumption. To sum up, the basic idea of consumerism is manifested in the following aspects:
1. Pursuing material enjoyment and sensory stimulation through consumption
In the field of material consumption, consumerism regards the possession and enjoyment of material products as the first priority of self-satisfaction and happiness, never stops stimulating people's needs, and positions people's value on the enjoyment and satisfaction of a single material life. People don't care about the consequences of consumption, don't consider the cost of environment and resources, ignore personal economic ability, and even take risks for consumption. In the field of cultural consumption, the trend of "culturalization" of goods and "commercialization" of culture is intensifying, and the essential difference between cultural texts and goods tends to melt. With the popularity of new media, a large number of cultural works are developing towards life, entertainment and consumption, and a large number of entertainment programs serve the senses and instincts of the audience. Pornography, murder and violence have become the themes of many film and television works, and humor, amusement and nonsense have become the creative principles of many works. In this case, people no longer pay attention to rationality and sublimity, but only to pleasure and excitement, and the metaphysical transcendence and promotion of cultural consumption will be transformed into metaphysical indulgence and degeneration.
2. Meet spiritual and psychological needs through consumption
According to Maslow's hierarchy of needs theory, people's needs are divided into different levels, and higher needs are based on lower needs. Only when people meet the lower demand first will they pursue the higher demand. In traditional society, due to the lack of material resources, people first meet the lower-level needs such as physiological needs, safety needs and belonging needs, while the needs of self-esteem and self-realization are not important in consumption choice. Today, due to the richness of material materials and the differentiation of homogeneous products, it is possible for consumers to pursue personalized and self-fulfilling consumption choices. Consumption choice is largely to meet self-esteem and self-realization, not just or even mainly to meet low-level needs such as physiology, safety and belonging. This situation is particularly obvious in conspicuous consumption, personalized consumption and fashion consumption.
3. Realize life goals and personal values through consumption.
Consumerism has established an idea in people's minds that the meaning and value of life can be found in what we have. Therefore, consumption has become the source and symbol of personal equality, happiness, freedom and happiness. For example, consumerism advocates that everyone can achieve equality through consumption. People can not only use consumption to smooth out the differences and discrimination between themselves and others in social status, income and power, but also individuals can improve their identity and status through consumption. At the same time, consumerism regards wealth and consumption as the standard of people's happiness. With the help of the Internet, advertisements, movies, television, etc., modern media skillfully integrate beautiful, romantic, magical and other cultural characteristics with commodities, creating various intentions that are not necessarily related to commodity consumption itself, making people feel that this is the so-called happy life, thus constantly stimulating people to devote themselves to the pursuit of this dreamy "happy" life.
After the emergence of consumerism in western developed countries, with the process of globalization, it spread to other developing countries with an unstoppable momentum. Even China, a nation with a tradition of "careful calculation", is deeply influenced. Some people begin to abandon the concept of frugality and rationality, and instead recognize and practice consumerism. Here, the global expansion of consumerism does not mean that wherever consumerism goes, people immediately live a consumerist life. What matters is not what people have, but what people want and what constitutes the basic meaning and pursuit of people's life. A correct view of consumerism requires us to adhere to the unity of historical scale and moral scale, not only to see its historical inevitability and progress, but also to see its moral limitations and harm.
Second, from a historical perspective, consumerism is an inevitable phenomenon in the process of social progress and people's free development.
Looking at consumerism from a historical perspective is to look at it from the era environment in which it came into being, rather than just using the current standards. The typical period of consumerism is the era of capitalist market economy. The market economy regards the market as the decisive means of resource allocation, and what and how much enterprises produce are determined by the market. In the market economy, individuals engage in production activities as independent subjects, and their labor and products can only be recognized by the society through market exchange and consumption, and their value can be realized. "In this case, the value of people is transformed into the value of things, and the relationship between people adopts the relationship between things. The relationship between things will inevitably lead to the domination and rule of things over people." But the development of consumption and people's own development was also realized in this period.
1. promotes the democratization and popularization of consumption to a certain extent.
Consumerism is a phenomenon that social productive forces have developed to a certain historical stage. In traditional society, the development level of productive forces is low and the means of production are scarce. Therefore, the ruling class advocates asceticism and hierarchy, so that ordinary people can meet the basic needs of survival, and a very small number of privileged classes can engage in material enjoyment and spiritual activities. From the essence of "consumption", only by satisfying the "consumption" of survival can we start the real "consumption" of people. After the industrial revolution, machine production completely changed the mode of production relying solely on human, animal and natural forces, and the progress of production technology made it possible to produce goods on a large scale. In the 20th century, Fordism was widely adopted, mass production made mass consumption a reality, and history entered the "affluent era", so consumerism came into being. In this case, people's consumption concepts and consumption patterns have also undergone major changes, which are embodied in two aspects: first, the consumption of industrial products is no longer monopolized by a few people or ruling groups, but aimed at the masses, who have become the goal of the industrial system, and some people call it "consumption democratization"; On the other hand, in the consumer society, the connotation of "mass" has also changed. It originally refers to the manual working class, which is the majority in society. At this time, the middle class whose income is relatively stable and has been expanding is also included. In this way, what was originally regarded as a luxury by the lower classes spread rapidly in the whole society, thus making the luxury goods of the past a necessity and quietly forming a mass consumer society.
2. Promote the development of people's free personality.
The realization of people's "free personality" value goal is based on the satisfaction of consumption. Marxism holds that human history "is the history of the development of individual's own strength". Taking human personality as a clue, Marx investigated the development process of human beings and combed the role of consumption in different stages of human personality development. In the social stage of "human dependence", limited by the development level of productive forces, people sell surplus products other than household consumption, and most of the products are consumed by family members, so people's production and consumption structure is in a narrow and closed state. In this case, people can't break through the limitations of their own activities, and there is no way to incorporate the social productivity of others into themselves, which determines that the relationship between individuals and others can only be political or blood-related dependence. People are bound to a certain family and political body, and it is impossible to express their personality and realize their independence. In the independent stage based on "dependence on things", consumption and production began to separate, and consumption was realized through currency exchange. In this way, people's dependence on commodity exchange and currency replaces social dependence based on blood relationship. This mode of production makes people get rid of the narrow bondage of the same body, breaks through various forms of personal attachment, forms independent individuals and their independent personalities, and provides a material basis for realizing people's independence, freedom and equality. From this perspective, consumerism is an inevitable phenomenon in a specific stage of human development. Compared with the past times, it is not only the inevitable trend of historical development, but also of great historical significance.
3. The symbolic characteristics of consumption make it possible to turn to the spiritual level.
In the consumer society, it is both anti-human and unrealistic to suppress people's desire for consumption. It can't restrain people's consumption desire, but it can guide people to turn their pursuit of material consumption to the enjoyment of spiritual consumption, and the symbolic and symbolic characteristics of consumerism itself contain the possibility of turning to spiritual consumption. A major feature of consumer society is that symbol system and visual image play an increasingly important role in controlling and manipulating consumers' tastes and fashions. "Meaningful consumption is a systematic symbolic operation." On the one hand, people show their own taste, identity, status and personality. Pass it on to others through consumption. On the other hand, people consume a certain meaning, mood, aesthetic feeling, grade, mood and atmosphere symbolized by the product itself. Thus, the symbolic characteristics of consumption reveal its inherent paradox: the more you pursue material consumption, the more it has nothing to do with human physiological needs. In this way, the symbolism and symbolic characteristics of consumerism construct a bridge to spiritual consumption. "Without the symbol system, people's life will be limited to their own biological needs and practical interests, and they will not find the road to the' ideal world'-this ideal world is open to him from all aspects such as religion, art, philosophy and science." Without symbols, there is no spiritual life. Without spiritual life, no one will transcend and develop reality.
Thirdly, from a moral point of view, consumerism leads to the dilemma of modernity and the crisis of human existence.
Judging consumerism from the moral scale is to look at consumerism according to the moral principles and concepts of today's society. From this point of view, the biggest moral defect of consumerism is that it pursues not demand, but desire, because human demand is limited and desire is endless. Infinite consumption to satisfy desires will inevitably impact the traditional consumption concept, affect the atmosphere of the whole society, and ultimately endanger the survival and development of mankind.
1. subverted the traditional consumption concept and cultural tradition.
In ancient society, both China and the West advocated the concepts of thrift, moderation, moderation and balance, and opposed extravagance, profligacy, greed and indulgence. Ancient thinkers in China generally advocated abandoning the concept of extravagance and saving. In the Analects of Confucius, Confucius pointed out that "courtesy is better than luxury, so we should be frugal" and "frugal in loving others", advocating thrift from governing the country to holding ceremonies and opposing extravagance and waste. "Zuo Zhuan" also mentioned: "frugality, virtue is also * * *; Luxury is the greatest evil, and "frugality" and "luxury" are regarded as important standards to judge people's virtue. Taoism requires people to "embrace what they see, be less selfish and less selfish", and advocates people to get rid of the bondage of material desires and pursue inner peace and harmony. Han Feizi, a master of legalism, pointed out in his study of Han Feizi's famous names that "those who are extravagant and lazy are poor, and those who are thrifty are rich", and regarded thrift as an important measure to measure the rich and the poor, and advocated thrift and thrift. Mohist school even raised frugality to the height of the rise and fall of the country, and put forward the concept of "frugality means advocacy, and lewdness means death" in Mozi's Ci Guo.
In ancient western society, the dominant concept holds that the value of life is the happiness obtained by pursuing virtue or God, not the happiness obtained by satisfying desire. Even in the early stage of capitalist development, Protestant ethics accumulated primitive capital for capitalism by preaching asceticism, punishing extravagance and laziness, and emphasizing asceticism's secular work and self-denial and atonement, and made diligence, hard work and thrift an important part of capitalist spirit. After the emergence of consumerism, luxury consumption, which pursues taste, fashion and status symbols, has replaced the concepts of thrift and moderation in traditional life ethics. At present, with the deepening of globalization, especially the appearance of new media, consumerism has spread to all parts of the world at an unprecedented speed and convenience with the help of modern media such as computer networks, movies, television and advertisements, and gained legitimacy and control in people's daily lives, which not only makes most people in developed countries imitate the lifestyle of consumerism, but also makes some people in developing countries worship, yearn for and pursue this lifestyle. In this case, the beliefs of "I consume, therefore I am" and "I will decline if I don't consume" dominate people's values and lifestyles, and the traditional frugal and moderate consumption concept has been completely abandoned and subverted.
2. It has caused intra-generational injustice and intergenerational injustice.
Since the industrial revolution, human beings have shown unprecedented strength in front of nature, but the development and destruction of nature have also reached an unprecedented level. The resulting environmental pollution, ecological destruction, resource crisis and other issues have made human beings begin to reflect on their previous production methods and development models. But it is one-sided to look at this problem only from the perspective of production and ignore the perspective of consumption. The close relationship between consumption and production requires us not to ignore the influence of consumerism on ecology and resources. Consumerism, which aims at satisfying endless human desires, encourages people to pursue material enjoyment crazily under the guise of constantly improving "quality of life" and "standard of living", which puts man and nature in a state of tension and opposition, leading to intra-generational injustice and intergenerational injustice.
On the one hand, consumerism has caused intra-generational injustice. Intra-generational unfairness is manifested in two aspects: one is the unfairness between developed countries and underdeveloped countries, and the other is the unfairness between different classes within a country. As far as the world is concerned, the total amount of earth resources is limited, but its utilization is uneven. Excessive consumption in developed countries leads to insufficient consumption in underdeveloped countries. In fact, 1∕4 people in developed countries consume 80% of the energy on the earth, while 3∕4 people in underdeveloped countries only consume 20% of the energy. Within a country, the luxury consumption of the rich is at the expense of the basic needs of the poor. Under the advocacy of consumerism, the poor worship and imitate the consumption patterns of the rich, which further aggravates the ecological and energy crisis. Therefore, in the case of certain resources and material wealth, the consumerist lifestyle can only be the privilege of the rich or rich countries, not the privilege of the poor and poor countries.
On the other hand, consumerism has caused intergenerational injustice. The social justice pursued by mankind includes not only all mankind in space span, but also future generations in time span. Because of the "absence" of real life, future generations can't declare their right to speak and compete for resources, but it doesn't mean that their rights should be deprived. Contemporary people should fully consider and respect the rights of future generations, and even consciously act as spokespersons for the rights of future generations. However, the formation and spread of consumerism make human beings' plundering of nature show an irrational madness and greed, which leads to environmental crisis and resource crisis, overdraws and deprives future generations of the same opportunities for survival and development as we do, and makes future generations face the dilemma of being unable to survive or even having nothing to consume.
3. As a transcendental existence, human beings have shrunk the spiritual world of human beings and lost their meaning, which is far from enough to satisfy their desires. Because what can best realize its essence in life is not infinite material enjoyment, but spiritual self-realization through individuality, uniqueness and creativity. The pursuit of spiritual needs can not only adjust the balance between people's material life and spiritual life, but also prevent people from blindly indulging in material enjoyment and alienating their inner world.
Under the guidance of consumerism values, people advocate material enjoyment and pay attention to present enjoyment, while ignoring the thinking of the meaning of life, intellectual development and self-improvement. The phenomenon of "shopaholic" and "online shopping addiction" in real life is a vivid portrayal. They can't restrain their shopping desire and consumption impulse. Shopping in online stores has become the theme and significance of life and has fallen into the complex of "no shopping". However, consumption cannot solve all problems. "Behind luxury consumption activities are more and more mental diseases and more and more social problems." For example, although some rich people live a life of high consumption, "depression", "boredom" and "boredom" have become the mantra, and depression and karoshi are plaguing more and more urbanites. In a sense, these problems are inextricably linked with the spread and popularity of consumerism. Schumacher, a famous British economist, pointed out that "human needs are endless, and endless needs can only be realized in the spiritual kingdom, but not in the material kingdom." Consumerism attempts to provide people with the basis of life and spiritual belonging by material satisfaction, which is undoubtedly to seek fish from the wood.
Fourth, the solution: to meet people's reasonable consumption needs and guide the spiritual turn of consumption activities.
Based on the above analysis, the author believes that we must adhere to dialectical materialism to treat consumerism. Consumerism is an inevitable phenomenon in the process of historical development and an inevitable stage of social progress and human development. This is an undeniable objective fact, otherwise we will definitely make a completely negative value evaluation of historical progress with productivity improvement as the core content. However, the emergence of consumerism has caused the dilemma of modernity, triggered environmental and energy crises, moral decline, lost meaning and other issues, endangering people's survival and development. "Even if a society explores the laws of its own movement, ... the law can neither skip nor cancel the stage of natural development. But it can shorten and alleviate the pain of childbirth. " Therefore, correctly judging and treating consumerism requires us to adhere to the unity of historical scale and moral scale, and we can neither avoid it as a scourge, nor let it flood and do nothing.
On the one hand, accelerate the development of social productive forces and meet the legitimate and reasonable consumption needs of the people. From the relationship between production and consumption, production determines consumption, and what and how much production determines the object and scale of consumer consumption. On the other hand, consumption has a negative effect on production, and the promotion of consumption capacity and the expansion of consumption scale are the prerequisites for expanding reproduction. Over the past 30 years since the reform and opening up, China has gradually bid farewell to the era of material scarcity and shortage and entered a period of relative prosperity. Therefore, it has become the goal of economic development to produce a wide variety of goods to meet people's growing material and cultural needs.
In this process, people's life has developed from insufficient food and clothing to a well-off society in an all-round way, and people's consumption structure has also undergone great changes. From the past rigid demand for food and clothing to the rigid demand for housing and behavior, it extends to enjoyment consumption and development consumption such as tourism, entertainment and re-education. The Engel coefficient of urban households and rural households decreased from 57.5% and 67.6% to less than 35% and 37% respectively. In this case, people's consumption enthusiasm and desire are gradually ignited and stimulated, and they pay more and more attention to the spiritual value, emotional significance and cultural connotation of goods from the past. This is the natural result of productivity and social development, and it is also the performance of improving people's consumption ability.
Especially at present, China's economic development has entered a new normal, the downward pressure on the economy has increased, the pulling effect of investment and exports on the economy has weakened, and the importance of pulling the consumption engine has become increasingly prominent. It has become an important trend to release the vitality of economic development through consumption. Among them, personalized consumption and diversified consumption will become the mainstream, and online consumption, service consumption, mass consumption and green consumption will become new highlights. How to grasp new consumption hotspots in the process of expanding domestic demand has become the key to promote the sustained economic growth of China. Therefore, it is an important value orientation to encourage people to actively consume, meet people's expectations of "hoping for a better life" and let people enjoy the fruits of reform and development. Meeting people's legitimate and reasonable consumption demand can not only promote economic development, but also improve consumers' quality, enhance people's subjectivity, enrich people's social relations, develop people's physical strength, intelligence and personality, and finally realize people's all-round and free development.
On the other hand, enhance people's consumption consciousness and guide people's spiritual turn of consumption concept. Consumption consciousness refers to people's sober understanding and rational grasp of certain social consumption culture and consumption mode, as well as their cognition, consciousness and reflection on their own consumption concepts, psychology and behavior. People's consumption desire cannot be suppressed, but it can be actively guided and channeled, that is, to guide people to enhance their consumption consciousness and realize the essence and harm of consumerism.
Of course, guiding people to switch to spiritual consumption is not a denial of material consumption, but an extension and promotion of material consumption, which not only conforms to the realistic requirements of taking the road of scientific development and building ecological civilization in China at present, but also fully considers how to transfer and eliminate people's troubles after eating. Because people's material needs are as limited as people's lives, the significance and value of people's spiritual achievements are infinite. Giving life meaning and value through material consumption is doomed to be short-lived and superficial, while the meaning and value spirit contained in the fruit of spiritual creation is permanent and profound. For example, whether a person eats and drinks in restaurants, shops in shopping malls, even gambles and takes drugs in his spare time, and whether he goes to libraries, concert halls, museums and other places to be influenced by culture and art reflects two completely different consumption mentality and behavior. The former is undoubtedly material, vulgar and even illegal, while the latter is spiritual, elegant and beneficial to physical and mental health. Therefore, only by actively guiding the spiritual turn of people's consumption concept can people enjoy material life without being blinded by material desires, promote economic development, realize the harmonious development of people's body and mind, and finally realize the integration and unity of social progress and people's all-round development.

These are confidential things, and ordinary people can't "find out" without technology. I just found them yesterday? Him? ? :"577..330.。 . 8 1 1, record "I took my wife's note", and they are absolutely grateful for keeping it a secret. Great! !
=========
Focal length Due to the special lens specifications of digital cameras, it is impossible to predict the range of scenes that can be shot from this data. Most manufacturers will increase the focal length of 35mm traditional cameras after the lens focal length parameters. If it is a souvenir or a photo of life, you only need to buy the fixed-focus lens model. If there are diversified needs, a camera with three times or more optical zoom capability will be more suitable. Focal length, also called focal length, usually refers to the distance from the center point on the lens axis to when the image can be clearly imaged. In a camera, it refers to the focal length of the whole lens group in mm (millimeter). The longer the focal length, the narrower the angle of the visual range of the lens, but it has the effect of magnification and proximity, just like the lens of a telescope; The shorter the focal length, the larger the shooting range and the smaller the relative object, which is suitable for shooting large scenes at close range, which is what we often call a wide-angle lens. For digital cameras, the longer the focal length, the longer the depth of the lens group. In addition, data such as f=5.5mm or 5.5mm can be found from the camera lens. However, because the focal length of the lens of a digital camera is generally much shorter than that of an ordinary 35mm camera, manufacturers often indicate something similar in the manual: a 36mm lens is equivalent to a 35 mm camera for users to compare.
Aperture range The larger the aperture, the more adaptable it is to insufficient light. If there are more than two aperture values, the application flexibility of the camera will be greater. Aperture is one of the important mechanisms that affect exposure. It usually refers to the control device composed of about 5 to 9 pieces of metal in the lens group, which can form circles with different sizes to control the amount of light entering the lens. The larger the aperture, the more light per unit time. The size of the aperture is expressed by numbers. The larger the number, the smaller the aperture, that is, the less light enters. All the marks on the lens refer to the maximum aperture of the lens, that is, the value in the fully open state, such as 1: 3.2, but on the zoom lens, you will see the marks of 9.2-28mm 1: 2.8-F3.9, indicating that the maximum aperture is F2.8 when the focal length is 9.2mm and the maximum aperture when the focal length is 28mm.
Shutter The shutter of digital camera can support 2 ~11000 seconds, which can meet the general requirements. Of course, if there is a wider shutter range, it can better meet all kinds of strict shooting conditions, such as shooting high-speed moving objects or starry nights. The shutter is used to adjust the exposure time of the camera. The unit is seconds, expressed in reciprocal. For example, 30 and 250 represent 1/30 seconds and 1/250 seconds respectively, so the smaller the number, the slower the shutter speed. The faster the shutter speed, the easier it is to capture high-speed moving images. Generally, it is not easy to blur the image due to jitter when shooting, but high speed may lead to insufficient light input. Usually, when the light is strong, you must use a high-speed shutter or increase the aperture. When the light is insufficient, a slow shutter is more suitable, but a tripod may be needed for assistance.
3. Macro shooting Macro is to zoom in and out the subject to be shot. The point is to shoot tiny objects to the size you want. In macro mode, various digital cameras have different abilities, and some can even close to 0. 1 cm for close-up.
4. Other functions, such as red-eye flashing, white balance and exposure compensation, will have greater flexibility for shooting in various environments.
The photosensitive part of automatic white balance correction digital camera is equivalent to the negative film of traditional camera. The photosensitive element of digital camera is fixed, so it needs the ability of white balance correction to reflect the change of light source. It is mainly designed for photosensitivity in different environments. Different light sources will produce different degrees of chromatic aberration, which may make the color blue and yellow, and the white balance correction can be corrected.
Exposure compensation Because the camera's automatic exposure function is based on the light entering amount of medium gray reflected light, if there is too much white (reflected light) in the shooting picture, the light entering amount will be higher than the photometric standard value, thus misleading the camera to think that the light is very strong and the aperture is reduced, resulting in underexposure of the photo and the white part becoming not white enough. Exposure compensation is to increase the exposure of 1 or 2 frames, so that a bright and correct image can be obtained. On the other hand, in most cases of black, it is necessary to reduce the exposure of 1 or 2 squares.
Many consumers, because they don't understand digital cameras, unilaterally think that pixels are high. Not exactly. When choosing a digital camera, we should consider its digital and optical characteristics.
1, digital camera lens. A well-designed high-end camera lens consists of multiple groups of lenses, including aspherical lenses, which can significantly reduce color shift and minimize graphic distortion and distortion. Expensive fluorite or glass is used as a lens. In order to reduce weight and cost, the lenses of household and semi-professional cameras are made of resin.
2. Image value of CCD of digital camera. CCD is the heart of digital camera, and it is also one of the main factors that affect the manufacturing cost of digital camera. Therefore, it has become an important standard for digital camera classification. At present, entry-level products are all 3-5 million pixels, and commercial and semi-professional users prefer products with more than 5-/kloc-0.0 million pixels.
3. Zoom of digital camera. Optical zoom is a real zoom, which will not affect the imaging quality of photos; Digital zoom is electronic zoom, which is a local enlargement at the expense of photo clarity.
4. Battery and power consumption of digital camera. Digital cameras have LCD screens and built-in flashlights, so the battery consumption is higher than that of traditional cameras. It's cheap to use the No.5 battery, and you can buy it anytime and anywhere, but it won't take long for the battery to die. Therefore, it is best to choose the model equipped with rechargeable lithium battery. At present, mainstream digital products have been designed as lithium batteries, and complete charging equipment is provided as accessories.
