Hi guys! I have what I hope is a quick/easy question. I have a couple of pixes on my computer that I want to retouch (remove gray from hair) and crop people out of. What software is best for this? I want to post them online (possibly). I have a PC, not a Mac. is this software that I might already have or will I need to purchase something new? Simplicity is the key word here--I am new to all of this. Thanks for your help.
