Hi all, first post, but i've been lurking around for a while, excellent forum.

Anyway, I recently bought the Creative Suite for school (Illustrator/InDesign mostly) but never really used Photoshop. Realizing I had some files from my old digital (Sony F828) still on my computer, I started to peruse them and came across some.
The pic below is straight from the camera, I only cropped it and of course converted it to a jpeg before posting it here. The original file is a tiff, I wasn't shooting RAW that day (yes I know, shame on me). Anyway, because I have no clue how to "post process" an image, I was hoping you folks could criticize it and throw a few newbie pointers out

Shot in Washington DC in the National Botanical greenhouse thingy next to the Capitol:

It is a bit overexposed. You can use the burn tool for some help. I would try to get the right exposure from the camera the next time, however, instead of trying to fix it in post processing.

If you have not done so, learn about the histogram and levels. I think that is a good place to start. Then go on to sharpening (unsharp mask).

Good luck,

Steve

Yea I know it's obviously not the best shot, it was just a random I pulled out of the dust. Thanks for the cpl pointers, I guess i'll just have to play around with this alot.
