How to control the exposure of pictures purposefully in photography
1. Photometry: When the lens is aimed at the subject, the camera will press the shutter button halfway to start photometry. The default subject of the camera is 18% gray (the film cover is standard 18 gray), which can also be understood as the camera shooting the subject as 18 gray. If the subject is brighter than 18 degrees, such as shooting a snow scene, the camera will automatically reduce the exposure and finally shoot the snow in gray. On the contrary, if you shoot a black object, the camera will automatically increase the exposure, and the black object in the final photo will be whiter than the actual one.
2. How can I take a real photo? This requires exposure compensation. For example, when shooting snow, we should make positive compensation, that is, increase the exposure to make the snow white, and when the shutter is given priority, open the aperture a little; When the aperture is given priority, the shutter opens for a longer time.
3. Control the picture exposure purposefully.
If you want to make the picture darker, you should make negative compensation to reduce exposure, otherwise you should make positive compensation.
It is also important to choose the appropriate metering mode, such as spot metering, center weighted average metering and so on.
The above is my little experience, and I recommend a photography website for you. Www.xitek.com has a photography foundation, a photo forum, a text forum, and equipment knowledge, which is relatively comprehensive.
I hope it helps you, and I wish you a happy life in the world of photography.
