At the risk of being a heretic let me make the following suggestions

It's been my experience that the gimp tutorials are helpful, but no
where near as complete as whats out there for Photoshop. That being
said, if you understand the techniques in photoshop, it's not to
difficult to map those to the gimp controls to do the same things.
I use GIMP for image manipulation.
though lots of resources are availalbe for photoshop, gimp docs are
hard to come by(from a photography point of view).
Can somebody link me to a good online guide.
I am looking for things like
1. Working with levels and curves, not just how to, but the technique too
2. Bulk watermarking, resizing
ImageMagik is your friend here
ufraw as a plugin to gimp (install gimp first, then ufraw) works really
nicely. At least as well as some of the commercial raw processors out
there. You might want to check out "noise ninja" too.
3. Using RAW under windows
I seem to remember that the gimp tutorials cover this as will most PS
books. Here's the problem. GIMP is only 8 bits of dynamic range per
color channel. Better digicams are 12 bits or better in their raw
format. Your display screen can handle that dynamic range, but last I
looked, your printer probably won't. So basically, what you're really
doing is compressing a much wider dynamic range into a smaller one.
Sometimes it looks right, and sometimes it doesn't. I think it's most
useful for pulling up shadow detail where you really notice digital noise.
4. Psuedo HDR by superimposing 2-3 images
I am a newbie, so I apologize if this has been discussed before. In
that case can somebody link me to the old thread?
