Common photographic methods

What are the common photography methods? The improvement of photography technology is the accumulation of experience, and learning from the knowledge and skills of predecessors can quickly improve our photo shooting level. Below I have compiled some common photography methods for you. Welcome to read for reference!

Common photographic methods

Sixteen rules of sunshine

For landscape photography, it is often impossible to obtain the best shooting effect by relying too much on the photometric results of the camera. For example, when there is a large dark field in the scene, the camera's metering system will increase the exposure, and the obtained photos will show the effect of overexposure, and the sky will become pale without any details.

Sixteen rules of sunshine

What if this time is adopted? Sixteen rules of sunshine? This will not happen. The intensity of sunlight is relatively fixed. When the camera aperture is set to F 16 and the shutter speed is set to1125 seconds (ISO is 100), you can take a landscape photo with strong colors and normal exposure. According to this rule, F/22 aperture should be used in the environment with strong reflection, such as shooting on the beach. When the light is weak, such as cloudy days, F/1aperture should be used.

Moonlight 1 1, 5.6 rule

The moon is the closest celestial body to us. It changes regularly. Since ancient times, those beautiful legends have made people daydream about celestial bodies all the time. At night, when you face the sky, the moon first comes into our sight. In ancient times, poets wrote poems about the moon. Nowadays, when people enjoy modern civilization, they all like to photograph the moon in their picture books.

Moonlight 1 1, 5.6 rule

According to professional measurement, when the full moon brightness value is EV 15, the normal visual effect can be obtained when the camera ISO is set to 100, the shutter speed is1125 seconds, and the aperture is F 1 1. In half a month's time, the exposure should be quadrupled. The exposure combination can be set to ISO 100, shutter 1/60s and aperture F5.6, and even the exposure time is nearly1sec when shooting the moon bud. In detail, it is not because of the change of their size that the brightness decreases, but because the angle of sunlight shining on the moon changes when the moon's profit and loss changes. Avoid overexposure when shooting the moon. More exposure will turn into a white circle without the feeling of the moon, so it is called the moon because it has a three-dimensional effect.

Camera jitter rule

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 1/50 seconds. Only when the environment is really dark, use a flash, tripod or put the camera on a hard object to prevent jitter.

Camera jitter rule

However, many digital cameras now have anti-shake function. Canon and Nikon, represented by mirror anti-shake technology, have advantages mainly in telephoto shooting ability. The effect of using mirror image stabilization in the focal length above 135mm is very obvious, and it can completely replace the three-speed safety shutter (for example, the shutter speed can reach 1/30 seconds after hand-held shooting is turned on at the 200mm end).

Grey cardboard rule

Grey board is a sharp weapon for shooting. But what if I don't have a gray board on me? You can spread the back of your hand (the palm is too white, and the color of the back of your hand is close to your face) to the sun, measure the light on the back of your hand, and add another exposure.

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.

Capture the dynamic law

This rule is based on the empirical formula of 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.

Sunset rule

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 look an hour later than it really is, you can reduce the exposure compensation by one step.

Flash distance rule

This rule is simple: distance times 2, sensitivity times 4. For example, when your flash is at ISO 100, the effective distance is 20 feet. If you want the flash to reach 40 feet, you need ISO 400.

Pixel doubling rule

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

Size rule of digital printing

If the work is to be printed as a large-size photo, the size of the photo cannot be greater than the length, width and pixels of the digital picture divided by 200 respectively. If the job requirements are high, score at least 250.

Exposure rule

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.
