I'm new to off camera flash and I can't figure out what I'm doing wrong with FEC. (Or if there is a problem with the Pixel Kings.) Basically, it seems to have no effect when I dial in FEC - I'm getting the same exposure no matter what I use for FEC. I'm using my T2i with a 430ex II speedlite (and obviously the Pixel Kings).
In the pictures below, the first has no FEC set. I wanted to bring down the exposure a little, so I hit the Q button and bumped the flash exposure compensation down a little. It didn't seem to make a difference, so as a test, I dialed it down to -2. No difference.
So I don't know if I'm doing something wrong or if I'm not understanding what FEC should be doing. I'm at a loss - any ideas? Is there some setting I'm missing or should be checking? Also, can someone else with the Pixel Kings confirm that FEC works with these triggers? I did check the flash menu and the mode was set to ETTL and I had it set to 2nd curtain flash if that matters.
