The red is due to poor light balance in the original, which I had to compensate for with the white balance adjustment in the RAW conversion program. My new strobe wasn't synching properly, and the Oly strobe has a very narrow beam and tends to be too hot in the center. When I adjust the WB during conversion, I have to choose between a dark blue picture with a very small area well lit, or a red foreground with some balance. I swapped the new D2000s for a Z240 with a hardwire and a Heinrichs/Weikamp ttl board, but I'm waiting while they're ordered. Hopefully, that will let me chuck the FL-20 and solve the hotspot problem. I've about had it with fiber optic links.
