Tony, that was comprised of 10 or 12 shots...I can't remember off hand. Here's the short list:
1) Stable tripod.
2) MLU and shutter release.
3) Exposure from - 2 to + 2 and everything in between, in 1/3 stop increments. I had the lens set at f/16, and cam at iso 100.
4) Once you've taken all the shots, come home, sit back, and work! haha. CS3 = File --> Automate --> Merge to HDR. Once all the files have been merged, a window will open up. Move the slider all the way to the right (yes, it'll seem dark, at first).
5) 32-bit file is generated. Now, you can clean up some stuff (dust spots, etc)...but don't do anything else, yet. Then, go to Mode --> and and convert to 16-Bitt Tiff. Another window pops up, with a drop down. Select 'Local Adaptaion' and expand the bottom part of the window, where it shows the graph. Now is where you have to 'tweak' the image so that it's not overcooked...which isn't easy...and you have to play with the curves. Once done, open the file.
6) Now, start to play with saturation, contrast, etc. till you get it to look natural. It should look exactly like a single exposure...but, contains 'every' little detail, in the scene.
HTH...and sounds way easy. It is, once you get the hang of it. Most important part, though, is with step 1 and 2...otherwise, you're images won't be aligned...and that just screws it all up!
