I assume that is the same thing that is done in camera when you take a jpeg- except with raw, the extra information is still available to rebuild the image within a range of exposures. what is the difference

RAW files are saved at 16bit while the jpg is in 8bit. With a jpg you are left with only 256 levels of brightness. A Raw file has the full range of the cameras chip available to you.

No caffeine whatsoever and meditating for three hours before shooting.

Okay, okay, infinitesymphony, I've been caught. I probably have more caffeine than blood in my veins most of the time....

Yes, diredesire hit it on the head--it's an auto-align function (in Photomatix in my case). If you look closely at the edges of the Photomatix HDR image I posted, you'll see just how off I was, as I didn't elect to crop off the edges (and so you can see just how off I was).

I may have to try that.

Yeah, Ed, but "HDR" is so much easier to say and spell than "ATOMMITHBAFALT."

Good point.

That's a very nice result. I'm really going to have to try that single-image RAW method.
