Dear Søren,

You can duplicate your selection, make your changes in the duplicated image, copy the optimised image, select your original image with the selection still in place and paste the optimised selection back in the ROI.

Best wishes

Kees

Subject: Contrast/brightness in selected areas

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
