red/blue swap (Gimp 2.9)
#1
I'm trying our IR photography and use Lightroom, but I've been using Gimp to swap the red and blue channels.  Works great, but I noticed that it doesn't seem to work right if I export the image from LR in Adobe Pro RGB colorspace.  When I do this, and swap the colors in Gimp, they look off.  The sky should be blue, but it looks more blue/green.

If I export the image in sRGB, the swap works as it should.  Any idea why this happens?

Welcome to gimp-forum.net

I do not have an IR image to try , neither do I use Lightroom, so can only offer slim possibilities (trying desperately not to write 'working-in-the-dark').

First thought, do you have the Adobe Pro RGB icc file available to Gimp?
When you open the IR image does Gimp ask what profile to use?
Have you set up Color Management in Gimp?

Sorry, I can't help you om that one. I might suggest you try Adobe's Photoshop forums for help. Just don't mention anything about using GIMP <grin>
