How to choose light parameters in figure photography

You can choose large aperture priority.

Meetings are usually held indoors, and the light is not particularly good. In addition, shooting close-ups of people with blurred backgrounds can simplify the background and highlight the main body, so the maximum aperture value is generally used.

If the shutter is too slow, the subject may move and it is difficult to shoot by hand. If the shutter speed is not fast enough, increase the ISO.

S5IS photoreceptor is only 1/2.5 inches, and the noise reduction ability of DIGIC III is not very high, so it is recommended not to use too high ISO value. Try not to exceed ISO400. Sometimes a little underexposure is acceptable, and it is easy to brighten up later.

If the lighting of the site is poor, add it to ISO800. If the light is poor, you can only consider using a flash. However, the flash index of this camera is generally not particularly strong, and it is only effective in a relatively short distance, which makes the photos stiff and dull.

As for the focal length, 80- 135mm (equivalent focal length) is the best, and there is no perspective blur. Just a little longer. It is always difficult to get together and take close-ups in front of others in meetings.

Shooting skills:

1. Take the long focal length lens as the main shooting lens (about 250mm lens for 120 camera or about 135 lens for135 camera), and take its short depth of field function.

2. According to the principle of portrait formula composition method, close-up, half-length, seven-point or full-body composition can be taken directly, about 5-8 steps away from the subject.

3. During exposure, according to the characteristics of portrait photography, the aperture compensation of 1 ~ 2 should be turned on to make the facial texture brighter. The light on people's faces is soft and bright, which is the focus of this kind of photos.

4. In order to create bright eyes, it is best to place a reflector or whiteboard in front of the portrait to make the eyes reflect bright spots.

5. When printing, it is best to follow the post-processing skills and soft focus treatment to completely soften the skin and make the whole photo soft.

6. You have to change the shape or props of the theme characters, otherwise the visual focus of the photos will remain unchanged, and the shortcomings of composition, depth of field and shooting techniques will be exposed.

7. Design the modeling style of the theme portrait, choose the scene suitable for the overall performance, and do a good job in the preliminary theme and scene design.

8. Usually, we should cultivate the ability of aesthetic composition, and draw up the overall composition plan between the theme portrait and the scene when shooting. Don't fall into the stereotype of portrait formula composition, take close-ups

9. Analyze the application of lighting on the spot, fuse the main body of the portrait to be photographed by addition and subtraction, and control the outstanding performance of lighting in the scene environment without falling into the common problems of general commemorative photos.

10. Control the length of depth of field, create a touching and advanced depth of field performance, and don't fall into the messy mode of ordinary life photos.

1 1. Choose the most suitable photo opportunity to press the shutter, grasp the vitality of the portrait and the artistic sense of the scene, and take a perfect portrait with scenery.

12. The most important thing to take this kind of photo is the choice of negative. As long as the black and white negative is used, the tone of this photo can be printed.

13. In the process of shooting, we should pay attention to the color of the background and props, especially the gray system, because too black and white background, props or clothes will make the photos produce all-black or all-white reaction when they are developed, which is the common sense of shooting black and white photos. Only when the gray scale system is suitable, the single tone of color printing overprint will have rich hierarchical performance.

14. When taking black-and-white photos, you can get beautiful colors by controlling the exposure correctly. Different from the color negative film shooting method commonly used by ordinary portraits, more than two exposures are often used to compensate. Only by correct exposure can we avoid the loss of saturated sound.

15. There is also a film produced by Ilford on the market, which can be directly developed into color without manual development of black and white liquid medicine, and the shooting effect is the same, which is a relatively convenient film.

16. After shooting and developing the negative, you can develop pure black-and-white photos through the black-and-white development process. Or through the printing process of color printing, a single-tone photo is printed.
