Ok, so a family member was cleaning out their closet and found a quantaray QA 25 flash. I have the D90, and for the life of me, I cant figure out how to get it to fire. I put it on the hotshoe and the ready light comes on, but every time I put the flash on, the on-camera flash pops up and that one fires. I cant figure out how to see if the thing works..any ideas? I have to be doing something wrong, or just am not doing something I should be. I looked in the D90 manual, and I cant find anything. Mark And can I say...WOW! 600 posts!!!!
