I have a new old flash. You see, my mom has an old Olympus OM10 which has a flash, which, it turns out, is the wrong flash for the Olympus (not a dedicated one, and as the OM10 is not able to go all manual, no good!). BUT it will (sorta) work with my Rebel! W00t! Again, not dedicated so won't go auto, but because I can put my Rebel on Manual, it will kind of work. Here's an experiment I did:
Without flash:

Exact same settings, but with flash bounced off the ceiling:

Am very excited.
