Gimp-Forum.net - Photo Light painting within Gimp

@page { margin: 2cm } p { margin-bottom: 0.25cm; line-height: 115% }
Hi All, I am looking for Tips/Help regarding Gimp navigation/layers. I have recently migrated from Windows to Linux as my preferred OS. I had been using the Adobe LR PS for my photo editing within the windows environment an option that is now unavailable to me in Linux.
I am looking to duplicate a technique I used in LR where I stacked photos as layers they could then be blended by using a brush I could expose the lower image (or part of) in my stack. The stacked photos are all of the same composition (night photography) but several photos were taken using a long exposure. Where some exposures I had performed some light painting to an object in the foreground. Hope that makes sense?
Can this technique be performed or duplicated with Gimp?

If you installed G'Mic Qt then maybe this is a sollution for you :

That sounds like a Layer Mask.

Thanks Blighty, think you cracked it. layer mask looks promising. figure I can play with that and duplicate the technique I have used with LR. Smile

As Blighty mentioned, masking. An example in gimp:
