Hello! I'm very new to digital photography, but I'm interested in learning as much as I can.
I've heard, and seen results, that post image processing is almost an essential part of digital photography, however, I have no idea how to do this. What would you guys recomend for a newbie, who is willing to learn/read, for a photo editor? I have PS7, but I don't know if that is outdated or not, or will still be good for my needs. If you would recomend something else, I would not want to spend more than 100 USD.
ALSO, HDR, or High Dynamic Range as I understand, yeilds some impressive images. I have no clue what this is, or how to do it, can someone link me to a site, or tutorial that explains this? Can I do this with PS7, or the software that comes with the Rebel XTi?
