ok I have never taken an HDR shot. I would like to learn about HDR photography, however. I was under the impression that there had to be 3 photos taken of a subject in order to compile an HDR photo. The main thing I need to know is the photographic process....starting at subject and ending in editing. I would like to add some HDR techniques into my photography.

edited to add a question.
ok

EL-ROI posted a link to a photoshop tutorial. According to the tutorial you need three pics....it even says to set up on a tripod. Ok how do you take a pic of an animal...i.e. dog, cheetah, etc. Animals just don't stay that still. If you have found one I need to send Dixie (my dog) over there for training.

You can do what's called a "pseudo" HDR shot by taking any single exposure and saving it as a +1 and -1 stop exposure, then combining those three.
You will find that you may need to do this, as well as some messing with shots in general, due to moving foliage and such.
I only occasionally use a tripod though, even when I take 7 shot brackets, because it works decently to hold steady and do a continuous shutter since the D300 w/ grip shoots at 8 fps. Slower fps is feasible to do this with as well, down to a point, so just experiment.
ETA: Also, you can simply tonemap any exposure which can give you that HDR-y look, or it can be used to get detail in shadows like here

ok my next question.....How do you tone map? I have been a hobbyist for a while but I have always been lacking in post processing...as my shots prove....lol. I do have photoshop cs-4

The DPC tutorial here is how I first learned, along with random reading here and there online. It's pretty easy to learn.
