Anyone shooting Aquatica 5000 19mm Dome in Photography Gear and Technique Posted December 19, 2002 Davephdv: Do you use TTL with your the WC-E68 and Aquatica dome port? I seem to consistently get overexposed shots with TTL and the dome port, especially with macro shots. The instruction manual seems to suggest that TTL can't be used since the sensor is blocked by the domeport. But, it seems that the dome doesn't obviously block that sensor. What's been your experience.
