I guess it's a combination of minimal focal length, maximum focal length 
and max aperture in the old exiftool program. While it would be a 
really, really nice feature to be able to look up images by lens (for 
some of us), we'd have to figure something out, and the user would end 
up having to ID the lens for the system the first time.... It would 
probably be worth it, but save it until you nail down the raw data 
before we start we start fighting this one...

I don't have a Rebel/300/350 here to mess with, but on Canon's Pro and 
"prosumer" bodies, you can specify the amount to over or under expose an 
image. it's called exposure bias, or "EV."

Oh, there it is, no wonder I missed it -- it's at the top of the list.

Since these are all "advanced" features, you could put them in an 
"advanced" dialog.
