For a hobby photographer who takes a lot of backyard photos of birds, flowers and family, and likes to play with photos (mirror photos, blend photos together) what does Adobe Photoshop offer that Graphic Converter doesn't? Both can read RAW images, adjust colors, remove things like powerlines and red-eye, apply things like reflections, water ripples and other silly effects, flip images, allow you to combine images, etc. Basically, my mom has and knows how to use GC, but all her photography buddies are telling her to get PS. I'd happily get it for her, but (1) it's incredibly expensive (2) I've never used it, so can't help her troubleshoot it and (3) it sounds just like GC which she already has and knows how to use. So what photo features is she missing out on by just having GC? Thanks!
