Photoshop is my editing program of choice. Why do I love it? It's good. Once you learn how to use it (I've been using is 3-4 years and still learn something new every day) it can be a huge tool.
Why do I hate it sometimes? There is something about a photo, unedited, that can be so beautiful. Babies don't have perfectly smooth faces, sometimes the light lets in a little extra blue...it's life! I've been working over the last few years, learning to edit less and make my photos more natural.
What else do I think about photoshop? Sometimes I think clients can be a little unrealistic as to what I can do (or how much time it takes me to do something) in photoshop. I get things like "you can edit out this water spill down the front of my shirt" or editing closed eyes open, and people in the background of a downtown photo session. Its a rarity to get too many crazy demands, but I love my job because I get to take a snapshot of the world around us, and keep it as natural as possible.
Sometimes, I really love to test my skills. For example, this little girl.

In the grand scheme of things, I love Photoshop, and would certainly recommend it to other photographers!
