Shooting HDR Pictures with Old Cameras (Part 2)

Continuing my series from yesterday, I swapped out my (2001) Sony DSC-F707 for my (2006) Canon Digital Rebel XTi (400D) and shot the same pictures.

Unlike the F707, the XTi does shoot in RAW. Where I tried (unsuccessfully) to use the automatic exposure bracketing on the F707 (as in, I didn't get evenly spaced exposures), I instead set the exposure bias manually on my XTi for the following images. (I'm not sure if the XTi has an automatic exposure bracketing setting?The exposure bias on the XTi can be manually adjusted from -2 to +2. I set the camera to shoot RAW and JPEG files simultaneously: The JPEGs are posted below; the RAW information is cited.)
