Digital cameras and their metering modes are always looking for a gray area, they dont want things to be too bright or too dark. that is why when shooting in snow you have to give positive compensation as it is trying to make all the beautiful white snow … Gray!
The same is true for skin tones as well.
- When shooting people with very Fair skin you will likely have to give a bit of Positive Exposure or flash Compensation
- whens shooting people with very Dark skin you will likely have to give a bit of Negative Exposure or Flash Compensation
