[Gimp-user] Images much darker in other editors

["Richard Kimber" <richardkimber btinternet com>]

I'm using the Windows 10 version of Gimp 2.10 .

When I create an image in Gimp to my satisfaction, if I display it in 
other Windows programs (e.g. Paintshop Pro) it looks much darker. Is 
there some option I need to set in order to have them look the same? I 
have set export gamma when I export to a png but that doesn't make a 
difference.

Basically, my problem is that if I were to send it away to be printed 
professionally, how would I know whether the print would correspond to 
the dark version or the light version?
