Not just for digital scrapbooking. I find these blogging challenges very educational because I try things I normally wouldn't try. The first Filter Friday Challenge at Rachel's site was to use the colored pencil filter on Photoshop. Hopefully, GIMP has that. I never would have published a colored penciled photo before this challenge.
What's really neat is that there is no deadline for her challenge!
Rachel's other filter challenges:
Sept. 7: Colored pencil filter
Sept. 14: Diffuse glow
Sept. 21: Mezzotint
Sept. 28: Glowing edges
