How to use the formula of camera gear algorithm

How to use the various gears of the camera? How to use it best?

There are many different modes of camera operation, and there are four common modes. Choosing a reasonable model can easily satisfy most of them.

I need it at the shooting scene.

The program is automatic, which is the most "flickering" mode. When taking pictures, the camera will automatically adjust the shutter and aperture according to the environment at that time, and take pictures in normal exposure, and can adjust the sensitivity and metering by itself. This mode is simple and easy to operate, but the photos taken are very limited, and usually only a very dull photo can be obtained.

When using, parameters such as ISO and white balance can be set manually.

The combination of aperture and shutter speed can be changed.

You can use a safe shutter speed and a moderate aperture as much as possible to satisfy most subjects.

Main uses: when the subject and background need to have a certain clarity, such as taking a commemorative photo.

Aperture priority. In this mode, by adjusting the size of the aperture, the shutter time of the camera is automatically adjusted according to the scene environment when shooting, so as to ensure that the photos with normal exposure are taken. For example, when shooting in low light, using a low shutter will cause the picture to blur due to jitter. At this time, keeping the aperture constant and adjusting the sensitivity will increase the shutter speed.

You can control the depth of field by controlling the aperture. Generally, large aperture (such as F 1.8) has small depth of field, while small aperture (such as F22) has large depth of field.

1. Try to use a large aperture when taking portraits, and try to use a small aperture when taking scenery.

2. If you want to blur the background, use a large aperture, such as F2.8 and F4.

F2.8

3. Use small aperture, F8, F 18, etc. So that the clearance range is large enough.

A small aperture can make the clear range large enough.

Shutter priority. In this mode, by adjusting the shutter speed, the aperture of the camera will be automatically adjusted according to the scene environment when shooting, and finally a normal exposure photo will be taken. This mode is suitable for shooting moving objects, especially fast moving objects. If the shutter speed is too slow, the image will be blurred easily. Setting the high-speed shutter directly can make the image clearer. Or shoot the traffic at night, and set a slower shutter speed to shoot the motion trajectory.

For general moving objects, 1/500 seconds can be solidified clearly.

It takes 1/2000 seconds or 1/4000 seconds for a high-speed moving object to take a clear picture.

________

When shooting waterfalls or streams, the slow shutter can create a smooth effect, 1/5 or even 1 sec, and it can also create a blurred effect, but a tripod must be used.

________

Can be used to follow photography. With a slow shutter such as 1/60 or1125, you can take photos with clear subject and blurred background.

Main uses: When shooting fast moving objects, such as racing cars and birds, you can capture them quickly. When using this mode, the success rate of continuous shooting can be increased. _______

Manual mode refers to the need to manually adjust the aperture, shutter and sensitivity according to the desired effect. Generally speaking, it is difficult for beginners to operate. Through constant practice, practice makes perfect over time.

It is often used when shooting special subjects, such as fireworks, lightning and smoke.

1, when shooting fireworks, set the aperture and shutter in advance, usually the aperture is F5.6 or F8, and the shutter speed is 1-4 seconds.

________

2. When shooting lightning, set the aperture to a small value, such as F 1 1 or F 16. And set the shutter to 30 seconds or B-door, so that lightning can be captured with probability when shooting.

How to calculate the gear in the exposure meter (how much is equal to how many apertures)

When you use an exposure meter to measure light, the exposure meter will give corresponding values according to the light illumination of the environment at that time, such as:125/16250/1500/8, etc. You set your ideal aperture speed according to this value.

Photographic gear conversion

Shifting gears is quite troublesome. It's actually quite simple. The displacement of the aperture is generally represented by f1.01.42.02.84.05.68.01162232. Shutter displacement is generally represented by T 1/232. 151/6011/251/2501/50011000 Each value differs by an ISO gear/. For example, if you set the camera to F4T1100 after shooting people,
