Hi,
I am designing a book cover. I have one layer for the image for the front cover, another for the back cover. I can easily adjust the brightness/contrast of the front cover image, but I cannot for the back cover image. Here's what I am doing:
1. Open dockable dialogue: Layers.
2. Select the layer I want to work on.
3. Select Colours -> Brightness-Contrast.
4. Adjust as desired.
5. Click OK.
With the front cover, the brightness/contrast change is immediate. With the back cover, nothing happens. I am using GIMP 2.8.10 on Lubuntu and Linux Mint (2 computers).
Thank you for your help.
