I have a D70s in an ikelite housing with two ikelite 125 strobes. The whole system works great when I have the strobes set on TTL, 1/2 or 1/4. But when I set the strobes to full power, the strobes fire but the light does not show up in the picture. I've tried several shutter speeds, etc. Do I have something set wroung? Thanks in advance for your help.
