Are you using a dslr? If so, get an external light source to go over the tank, then up your shutter speed and switch to manual focus. Then focus on a spot the cb goes frequently, and just wait for it to swim by and start snapping. Helps if you have a tripod. I've had a 6 line wrasse for a while now, and could never get a good pic of it until I did that.
Nice looking tank. Is that a lawn mower blenny in that first pic? I love their personalities.
I use an old piece of crap point and shoot digital camera. I adjust my Kessil to the right spectrum and intensity for photo shoots. Then adjust it back. Then I open my photos in Photoshop and adjust them to match what my eyes see in person.
Do you lose any of the color in your corals when you do that?
By losing color in them, do you mean their appearance in the photos? Yes, it has to be adjusted in Photoshop a bit so you can see what I do. It has no effect on the corals themselves as the light is adjusted only for a few minutes while I take the pics and then it's adjusted back.
Not really any different than cloudy days or storms, etc. Light is never really a constant on a real reef.
Yes, I was only referring to the photos
You know its interesting that though I do lose some color in my corals when I adjust for shooting pics, I gain in other colors. Really, the only color I lose is that intensely insane "glow" of the greens under actinic lighting. But under that lighting I lost so much of the natural color of everything else that I prefer the more daylight spectrum for photos.
