ya we havn't quit figured that out yet, I am leaning towards the snorkel is too close to the flash and its not letting light into that side ;-( but not really sure, I was hoping that it was because maybe some of the flash gasket was hanging a little over (didn't have the right tool for cutting the holes in flash gasket) but I don't know cause I changed it over to video yesterday to see how that works out, so will have to test the flash part next time to see if I fixed it or not by peeling some of the flash gasket off the left side
