Maintenance strategy of mobile phone shooting
This picture book is the most helpful of several related books I borrowed from the library. It not only explains the composition, lighting and color of photography, but also provides guidance on using snapseed to retouch pictures in the later period, which is very helpful for me who has been using snapseed. The following is my simple arrangement of this book.

1. Use exposure compensation to make the contrast between light and dark more obvious: slide the little sun on the camera screen up and down.

2, accurate metering to ensure accurate exposure of the picture: Under normal circumstances, the focus of the mobile phone and the metering point are together, and the brightness of the picture is adjusted by moving the position of the metering point.

3. Turn on HDR mode to deal with the high light ratio environment: when there is a big difference between light and dark in the shooting environment, this difference will affect the performance of bright details or dark details of the subject. If you want to keep the bright and dark details, you can turn on HDR mode. However, not all scenes are suitable for turning on HDR mode. There are many artistic pictures that need contrast between light and shade, such as shadows and reflections in the pictures. At this time, turning on HDR will only reduce the contrast between light and dark and lose the original desired effect.

4. Different measurement areas:

? Spot metering: metering a small area of the picture, which is suitable for situations where the contrast of light in the scene is large or the main body accounts for a small proportion in the picture, such as silhouette effect.

? Central focus photometry: the focus of photometry is in the area of the picture, accounting for about 75% of the picture. This metering mode is easier to control the effect than matrix metering in the case of large color contrast of light.

? Matrix photometry: The mobile phone can automatically measure the exposure value, which is suitable for situations where the contrast between light and color in the scene is small.

5. continuous shooting: Hold down the shutter.

Step 6 delay shooting

7. Auxiliary line

8. Panoramic mode: Let the same character appear in the picture many times.

Tip:? Underexposure, post-repair is better than overexposure.

1, different frames:

? Horizontal frame: the picture is natural

? Mullion: Displays vertical lines and a sense of depth of the picture.

? Box: The picture is balanced and stable, which is often used for solemn and stable subjects.

2. Three-point synthesis method

? Horizontal three points: landscape theme, upper three points, lower three points, keep level when shooting.

? Vertical three points: people, animals and flowers.

? Symmetrical composition: left and right symmetry, up and down symmetry.

? Frame composition: arrange the main body in a frame, such as windows, doorframes, branches, caves, etc.

? Open composition: the main body of the picture or the rest related to the main body is cut out of the picture, giving people room for imagination.

? Closed composition: the picture structure is independent and complete, and the main body is in the center or golden section.

? Multi-point chessboard composition: There are many subjects with the same elements in the scene, giving the picture a strong sense of rhythm. Pay attention to adjusting the shooting angle.

? Minimalist composition: the main body occupies a small area, leaving a large area blank, paying attention to the simplicity and cleanliness of the picture and the collocation of light and color.

3. Subtraction in composition

? Close to the subject, blur the background

? A large area of pure white space is reserved when shooting.

? Change the shooting angle to avoid clutter.

4. Addition of ingredients

? Keep the picture simple and add only one bright spot.

? The added elements can add points to the picture.

1. Vertical lines: The use of vertical lines in landscape and architectural themes brings a sense of stability, straightness, solemnity and toughness to the picture.

2, radiation: the use of radiation lines, so that the picture presents an open, dynamic, atmospheric, and a certain sense of strength.

3. Diagonal line: people, scenery, animals, buildings, etc. You can use diagonal composition to avoid messy scenery.

4. Curves: Make the picture look more rhythmic, such as rivers, highways, mountains, forest paths, overpasses, etc. The common forms are English letters "S" and "C"

5. Convergence line: Guide the picture to converge and extend far away, so that the picture presents a three-dimensional effect.

1, different angles: look up, look up, look down, and choose different perspectives.

2. Use various contrast relationships to compose a composition: size contrast, dynamic and static contrast, light and dark contrast, color contrast, and virtual and real contrast.

3. Different light: direct light, scattered light, front light, metering, backlight and side backlight.

4. Learn to control the light ratio: large and small light ratio, strong and weak light ratio, and light at different times.

1, TIC-tac-toe composition: The positions of the four intersections of the composition line are the golden section positions of the picture, and putting people near these positions can make the picture more harmonious.

2, the central point composition: can highlight the main body.

3. The matching of clothing color and background color of socialist figures.

4. Open composition: more abstract artistic sense.

5. Use different angles: head up, head down, low angle, front.

6. People with their backs to the camera: Pay attention to the posture of the characters and try to choose an open background.

7. Use different scenes: panorama, bust and close-up.

1, perspective: adjust the deformation of the main body and repair it automatically.

2. Rotate: Straighten the picture

3. Expansion: Expand the screen space, mostly for simple areas.

4, white balance: adjust the color temperature and coloring, and adjust it more finely with a straw.

5. Curve: Not only the sensitivity of the picture can be adjusted, but also the proportion of light and dark areas in the picture can be adjusted. At the same time, three different channels of red, green and blue can be used to combine different filter effects.

6. Adjust the picture (this function is also commonly used by me): brightness (underexposure), contrast (gray picture), saturation (dim color), atmosphere (changing natural saturation and light and dark details), highlight (brighter picture), shadow (increasing the brightness of shadow area or reducing the silhouette effect of shadow) and warm tone (adjusting cold and warm tone).

7. Highlight details: Use structure and sharpening to increase the clarity of the picture and increase the expressive force of details.

8. Local: Adjust local brightness, contrast, saturation and structure.

9. Brush: Adjust local lighting, editing, exposure, color temperature and saturation.

10, Halo: creates a contrast effect between light and dark.

1 1, lens blur: controls the depth of field of the picture.

12, Repair: Repair defects in the picture, such as unwanted elements entering the picture.

13: filter: HDR landscape, charming halo, mottled effect, coarse-grained film, retro effect, nostalgic effect, black-and-white movie, black-and-white photo frame, mask (very powerful and against the sky), beauty (brightening face, rejuvenating skin and brightening eyes), and head shape (dealing with facial expressions, such as pupil size, smile and focal length).
