Had a go at HDR last night
Discussion
I managed to aquire a copy of Photoshop CS2 over the weekend and I've been having a little play.
....no samples to embarass myself with I'm afraid!
The lighting results weren't exactly spectacular and worse still there was a sort of slight motion-blur on the finished image.
I presume this is due to the camera moving in between takes? It was on a tripod, but I was manually adjusting the shutter speed (all else left the same) and firing the camera so I guess I must have knocked it a little. Do I just need a better tripod and a remote trigger or is there likely to be more to it than that?
The process appears to be fairly idiot proof. You select 3+ images, it runs a procedure and you end up with the HDR image. I presume there are some settings to fiddle with somewhere.
Anyway, can anyone offer me some tips?

you don't necessarily need 3 shots. In CS2 open your photo then go to Image, Adjustments, Exposure and adjust the Exposure to -2 then save the shot as shot1 (for expample). Then adjust the Exposure again to +2 and save as shot2 and again change the Exposure to +2 and save as shot3.
Never done hdr in CS2, I normally use Photomatix, but the above helps if you only have one shot to use

Do you get the same sort of effects altering the exposure digitally from the same base image then?
Can I ask a random CS2 question whilst I'm here - why can't I save my HDR images as jpg? If I load a normal photo I can save it as just about anything (including jpg) but my HDR experiments would only save to about 4 different formats.
Also, can anyone suggest a good test image to demonstrate HDR on? I assumed something with plenty of light and dark, so (based on what was available in the house at night) I tried a photo with most of the lights of, but one intense strip light in a corner of the shot, the montior glowing on the other side and the flashlight from my mobile on the other! (Serious setup
) What I mean is, what sort of thing (around the house and at night) could I show off the results with?

It could be that the file is 16bit you will have to convert it to 8 bit to save as a jpeg Image>mode>8bits/channel
