Just curious, is the white balance off on 3,4, and 5, or you used some other sort of lighting combo? Based on the lights i see, that's one bright ass tank. Pic 3,4,5 looks like a sundown pic. Are there any moonlight on the tank? I really like the way they look, gives it a feel of peacefulness. But the color is throwing me off, based on the overall look of the tank.
Can't speak to the camera issues, but the lighting is 4 250 DE Phoenix 14K lamps on Icecap ballasts and in Icecap pendants. Nothing changed from shot to shot other than BC's machinations.
SE Reeflux 10K w/ actinic VHO. Quite liked them too. I think ambient room light plays a big role in how we perceive these lamps. The same setup on my 125 in another room closer to the windows looks really different and not as nice IMO.
