Photography techniques 12

I. Sunny 16 Rule)

The "Sunshine sixteen law" is a method to correctly estimate the exposure values in sunlight when no metering table is available. Therefore, this law is applicable only when there is plenty of sunlight. Set the aperture to F/16, and the shutter is synchronized with ISO, or a little faster. For example, when ISO is set to 100, the shutter should be set to 1/100 seconds (1/125 seconds ). Therefore, the F/22 aperture should be used for photography on the beach, and the F/11 aperture should be used for multi-cloud photography.

Ii. Moony 11, 8and 5.6 Rules)

If you want to photograph the moon, there is a good rule. When the shutter is synchronized with ISO, F11 aperture is used for the full moon, F8 aperture is used for the Month of the string, and F5.6 aperture is used for the new moon.

3. Camera jitter rules (Camera Shake Rule)

When shooting with a camera in your hand, the shutter speed cannot be less than the reciprocal of the lens focal length. If the shutter speed is slower, the sharpness may be reduced when shooting jitter occurs. If you use a 50mm focal length, the shutter will take more than 1/60 seconds. When the environment is dark, use a flashlight, tripod, or place the camera on a hard device to prevent jitter.

4. Gray Card rules (Anatomical Gray Card)

Carrying the 18% medium gray panel with you is a powerful tool for shooting. But what if there is no gray board on the body? You can open the palm of your hand to the sun, measure the palm of your hand, and then add an exposure.

5. Depth of Field Rules)

When the object to be taken is relatively deep, the focus should be at the first 1/3 of the depth of field, because in this way, the depth of field after the focus is twice the previous. This rule can be applied to all kinds of aperture and focal range combinations. Remember, the smaller the aperture, the shorter the focal length, and the longer the distance from the object to be taken, the larger the depth of field.

6. Digital printing size rules (Largest Digital Print Rule)

If you want to print a large-sized photo, the size of the photo cannot be greater than the length, width, and pixel of the digital image divided by 200. If you have a high requirement on the image, divide at least 250.

7. Exposure Rules)

When processing digital photos, the most common rule is to ensure that the exposure of the highlight area is accurate and that the low-light area will follow him. However, when processing a negative slice, especially a colored negative slice, you 'd better add one more.

Quick Flash-fill Rule)

When your camera cannot automatically output a controlled flashlight, set the sensitivity of the flashlight to twice that of the film. If you measure the Light of the subject, select the whole aperture for the fuselage, and set the flashlight to the same aperture. In this way, the shadow area of the photo is lower than the brightness of the subject.

9. Flash Range Rule)

This rule is simple: multiply the distance by 2 and the sensitivity by 4. For example, when your flashlight is in ISO100, the valid distance is 20 meters. If you want to increase the flashlight distance to 40 meters, you need to increase the sensitivity to ISO400.

10. pixel doubling Rule (Megapixel Multiplier Rule)

If you want to multiply the resolution of a digital camera, it is very easy, that is, to multiply the pixel.

11. Action-stopping Rule)

This rule is based on empirical formulas of angle and speed. If you can capture an object along the axis of the lens with a 1/125 shutter, it can capture the motion of the axis of the lens in 1/500 seconds. That is to say, if an object is known as 45 degrees of motion along the axis of the lens, the shutter speed is only 1/250.

12. Sunset Rule)

When shooting the sunset, measure the light in the upper part of the sunset, but do not let the sun appear in your viewfinder. If you want to make the sunset look one hour later than the actual time, You can subtract 1 from the exposure compensation.
