I can see you making $100 to $200 without too much difficulty thus just keep shooting away 

Thanks guys, that's nice to hear (read)! I'll be going to Thailand soon, and I'm very curious to see how the Thai pics will sell
And thanks for the suggestion steheap, I'll do that. Need to go into the whole model release thing, which I was avoiding, but doesn't seem too complicated though.

I have made the opposite experience. My unedited images sell better where I have not increased saturation. DT once wrote to me and told me not to edit them so that the buyer can edit the images to their liking. I think you're doing very well.

Thanks for all the advice guys!

Brasilnut, tu � brasileiro mesmo ou s� algu�m fan�tico pelo Brasil? hehe de qualquer forma, obrigada pelas boas vindas

Oh and about Alamy, I thought it would be a good idea for me also since I like taking Editorial photos, but I failed the QC because my digital camera "is not suitable for Alamy". Once I can afford a better one, I'll surely try again.

And yeah I've read that pictures with a lot of contrast and colors sell more, but I've also read that more natural pics are better, as HappyBunny said, so that the buyer can edit them as they wish. So, I guess I'll try to offer the buyers both, some pics I'll do more contrasty and saturated and others more natural. Hard to know what the buyers want in this business sometimes... so many different people with different needs, I guess the key is really to try to diversify.

And thanks for the tip about using the "filtro graduado", solucionfotografica! I use LR, but I'm not really an expert on it and there are still some features I don't know how to use (or for what). Now I just saw some tutorials about the graduaded filter and I can see how that will help me a lot.

Cheers,
