After sen2cor

I am wondering to normalize the pixel number of sentinel-2 from 0-255 in snap.
Is that possible?

I have done atmospheric correction through sen2cor

In general normalization in remote sensing refers to a process that make the comparability of two or more products.

comparing two images from two different time periods for a land cover change detection,the first step is, to remove the effects of atmosphere by ‘atmospheric correction’. This what you exactly have done by applying sen2cor to all of your granules.

yes, thanks falahfakhri. It solved.
