All the photoshoping in the world won't fix a bad photo. Great photos start with great captures, imo.
I couldn't have said it any better myself.
I'm an "accidental photographer" and am doing this all backwards. Whilst I've been shooting for 6 years now, I really don't know anything, hence why I joined the forum. I seriously want to learn. I think that's the biggest thing...get to know your DSLR and the aspects of composition, exposure, etc. It's just been dumb luck that I've been able to hock some of my shots to tourists from away...But then it seems like people who visit coastal Maine, where I live, just want souvenir shots anyhow and that's what mine are good for.
Anyhow, I have the same dilema as you. I've avoided PhotoShop for years because I think I'd be tempted to "cheat" if that makes sense. I want what comes out of my camera to be genuine and not embellished or over the top. Not that most pros do that. Just sayin'! And again, if it's not a good shot to begin with, there isn't much that PS or any other software is going to do to cover that up.
However, I have recently caved and bought Elements and have ordered Lightroom. But until I get them loaded on my new computer, I'm OK using Picassa and Picnik.
Picassa is really easy to use and converts/reads RAW files, which is nice because I will either shoot in both RAW/JPEG or just RAW. However, now that I've discovered Picnik, I'm a little more enamored of it, than I am Picassa. I don't know if it reads/coverts RAW files or not though. One thing I have noticed about Piccassa is that the "sharpening function" isn't that great. It's like the shot either ends up too sharp or not sharp enough...there seems to be no inbetween. But it's free and you know the old adage about getting what you pay for!
Someone might mention GIMP. It's a lot like PhotoShop but doesn't quite have all the bells and whistles. And it's free or can be downloaded for a small contribution. I do know that it converts RAW files. But like PhotoShop, it intimidates the hell out of me and whilst I have played with both GIMP and PS, GIMP is nowhere near as user-friendly as PS. But you might want to download it just to see if you can work your way through it. It might help you decide if you actually want to invest in PS.
Sorry for the novel. I hadn't realized I had so much to say. Hope at least some of it helps!
