cell phone tripod

The above photo is metered with water, and the sky is overexposed. If you don't want to adjust the metering point, you can reduce the cell phone tripod
exposure compensation by one or two.
This is metered in the sky, the water surface is underexposed, and you can add one or two exposure compensation.
This is a mid-tone cloud to measure the light, the picture is relatively balanced, in line with the situation at the time, there is no need to increase or decrease the exposure compensation.
Exposure compensation is a very simple matter, don't make it complicated.
I believe that many experienced photographers will not consider exposure compensation when shooting. Either the experience of metering the picture is very rich, the effect of the picture is the cell phone tripod effect that you want, and finally make up later. Either take a look at the effect, and increase the exposure by a little exposure. I will not go to the principle of white and black reduction. There is also exposure compensation for later considerations, whether it is better to overexposure or underexposure, depending on the needs you want to perform.
