What you need to do is take 3 consecutive pictures of the same scene with different values of exposure (you'll need a tripod to eliminate any shifts in the scene). If you camera has "Exposure bracketing" you can use it to achieve that. Once you enable exposure bracketing, your camera will take 3 pictures where the scene will be underexposed, properly exposed, and finally - overexposed. You then take the 3 images (could be more if you wanted to create a more refined range), and create an HDR out of them in PS.

With regards to PS CS3, open it up, go to File --> Automate --> Merge to HDR... Choose the three images and PS will create a baselined HDR for you. From here, you can either accept the default values, or you can take further and do tone mapping to adjust the results.

Tone Mapping is a bit more involve than to explain in a few sentences, but Google is your friend there is a wealth of information out there that explains the features of tone mapping and what can be done with it.

I did that, and I just get junk. I'm going out now to take some pics specifically for this project. How far should I +/-? Full stop? More? Less?

Up to you. The camera lets you adjust it. I think the default is 1 stop increments and they go up to 3 stops I believe.

I'm sure there is a less of a retarded way to do it, but here goes:

1. Create a new folder and put the new HDR (saved as .PSD) in it

2. In PS, File --> Scripts --> Image Processor...

3. Choose source folder, destination folder, set JPEG compression/quality to '12' (highest), check off "convert to sRGB.

4. Click "Run"

to save it as a jpg goto image -> mode -> 8bit.

it'll ask you to make some adjustments, and then you can save as a jpg.
