Hi Ed,

You can merge the channels first and then adjust the levels of each channel independently by going to Image - Adjust - Colour Balance. Select the channel that you want to adjust from the drop-down box, e.g. Red) and the changes will only be implemented to that channel.

Kind regards,

Jacqui

Subject: [FORGED] Per channel contrast adjustment?

This is probably a simple question, but my google-fu is failing.

I have a red, green, and blue image I want to turn into a single
RGB image.  These images are of varying levels of intensity,
and all I care about is how visible all three are on the final image.

I can contrast each of them easily enough, and combine them
with Stack to RGB.  But I find myself repeating this procedure
over and over, trying to get the best image.  Is there a way I
can adjust the contrast of a single channel and preview it live?
