thanks sa7an.
In all shots where I used multiple exposures, yes, I used a tripod. Except the last one. I didn't have it along with me so I set my cam down on a wall and shot from there. It's possible to get better-than-normal dynamic range using a single exposure if you shoot RAW. you'll probably end up with a lot more noise depending on the composition, but it does usually work pretty well.
Don't be afraid to post more HDR shots if you've got'em guys, this isn't "my" thread. I like what you've been posting and would love to see more.
