Up to this point I've been relying on Graphic Converter and iPhoto for my editing tools, but I think I'm outgrowing this software. Most photo-editing tutorials are based around Photoshop, so I'd like to be able to use that software. I can't afford Photoshop right now, but was considering getting Photoshop Elements. Is it worth it for someone planning to use Photoshop in the future but unable to afford it now? In particular, can I use it to learn more advanced techniques that take advantage of my SLR's capability, or is it too "dumbed down" for that?
