Hi, it's nice to know that I'm not alone here representing Brazil
Eduardo, seja bem-vindo ao fórum, eu também sou iniciante, e pode ficar tranquilo que o pessoal do fórum é bastante solicito e vai te ajudar bastante.
I have some doubts similar to Eduardo's. I have already downloaded GIMP, but I haven't started to really use it - only to convert photos to smaller sizes - and at the moment I cannot spend money in software , and I still don't shoot RAW - I have a CanonSx20is, only JPEG - so if you can suggest some nice tutorials for me I'd thank a lot
