I have a P20 external flash from Kodak that I used to use for my old kodak dslr. Does anybody know of any possible way to jerry rig it to be able to work at all with a Canon Rebel XS? I do not have any money to purcahse a canon external flash at the moment, and I do not want old flash to go to waste. Maybe some combination of extension cords, I have no idea. ANY help would be GREATLY appreciated. I have no idea if this could even be possible.
