Twelve techniques of photography

1.Sunny 16 Rule "Sunny 16 Rule" is a method to correctly estimate the exposure value in the sun without an exposure meter, so this rule is only suitable for use in sunny conditions. Set the aperture to F/ 16, and the shutter is synchronized with ISO, or slightly faster. For example, if ISO is set to 100, the shutter will be set to1100 seconds (1125 seconds). Therefore, according to this rule, F/22 aperture should be used for shooting on the beach and F/ 1 1 aperture should be used on cloudy days.

2. moonlight 1 1, 8,5.6 rule (moony 1 1, 8,5.6 rule) If you want to shoot the moon, then here is a good rule. When the shutter is synchronized with ISO, F 1 1 aperture is used for shooting the full moon, F8 aperture is used for crescent moon, and F5.6 aperture is used for crescent moon.

3. Camera jitter rules

When you shoot with a camera in your hand, the shutter speed should not be less than the reciprocal of the focal length of the lens. If the shutter speed is slow, the sharpness is more likely to decrease when shooting jitter. If a focal length of 50mm is used, the shutter should be above 1/60 seconds. Only when the environment is really dark, use a flash, tripod or put the camera on a hard object to prevent jitter.

4. Grey card of anatomy.

18% medium gray version

Carry 18% medium gray board with you, which is a sharp weapon for shooting. But what if I don't have a gray board on me? You can open your palm to face the sun, measure the light on your palm, and then increase the exposure.

5. Depth of field rule

The depth of field in the back is twice that in the foreground.

When the subject is deep, the focus should be in front of 1/3 of the depth of field, because the depth of field after focusing is twice as large as before. This rule can be used in various combinations of aperture and focal length. Remember, the smaller the aperture, the shorter the focal length, and the farther away from the subject, the greater the depth of field.

6. Maximum digital printing rules.

If the work is to be printed as a large-size photo, the size of the photo should not be larger than the length, width and pixels of the digital picture divided by 200, and if the work is very demanding, it should be divided by at least 250.

7. exposure rules

When dealing with digital photos, the most common rule is to ensure the accurate exposure of high-light areas and let low-light areas go with him. But when dealing with negative films, especially color negative films, you'd better expose one file.

8. Fast flash filling rules.

When your camera cannot automatically output the control flash, set the sensitivity of the flash to twice that of the film. If the body measures light, select the full aperture of the body and set the flash to the same aperture. In this way, the shadow area of the photo will be one step lower than the brightness of the subject.

9. Flash Range Rules

This rule is simple: distance times 2, sensitivity times 4. For example, when your flash is at ISO 100, the effective distance is 20 meters. If you want the distance of the flash to reach 40 meters, you need to increase the sensitivity to ISO400.

10. Pixel multiplier rule.

If you want to double the resolution of a digital camera, it's easy to quadruple the pixels.

1 1. Stop action rule is an empirical formula based on angle and speed. If an object moves along the lens axis, you can capture it with the shutter of1125, then its movement behind the lens axis can be captured with 1/500 seconds. That is to say, when the object moves 45 degrees along the lens axis, it only needs a shutter speed of 1/250.

12. Sunset rules

When shooting a sunset, measure the light above the sunset, but don't let the sun appear in your viewfinder. If you want the sunset to appear one hour later than the actual one, you can subtract 1 from the exposure compensation.
