Hi all

I am new to IMAGEJ/Fiji and have some troubles.

I have a TEM picture which is composed from 4 collectors and merged automatically into one picture.
However, the setup is not calibrated properly, leading to different contrast/brightness for the different collectors.
Therefore I am trying to go through the four sub pictures one by one and adjust the contrast so that I get a nice final picture

However no matter what I try the adjust contrast/brightness is effecting the whole image and not the selection I have made.

Hopefully it is possible to create a macro that can do this adjustment for all of my pictures, but right now I just need help getting started.

A sample image can be found here:

Thanks in advance
