today I decided to play a little bit with chanel based saturation. And for this I decided to annoy lindsay fish 'diablo" a little bit which is by now 33 cm long.

So we put on flash to the right site of the tank, one flash on top of the tank and taking 10 - 20 picture to find the right exposure for this job.

Sadly I was not able to use autofocus, cause the water was playing havoc with the system from my D50. If you look at the picture, specially close to the Fin you can clearly see the scratch, which I still need to correct in photoshop, but this will take a little bit. The fish is fairly complex with all his scales.

now about these specific look,

this is actually very easy to accomplish you just need to reduce the saturation of each color channel. In this case it was green/yellow to remove the color from the plant and blue/aqua to remove the water color.

did I mention I love light room? It is so simple todo these kinds of things. And like always we have trouble with the blown highlights. Because the scales are so reflective. I tried to compensate for it, but it doesn't always work as i want and these where the only usable shots out of 100 pictures or so.

oh last, but not least use a circular polarizer to remove reflections from the fishtank. This can be even improved if you turn off all lights in the room. The used aperture was around F/8 and the used shutter speed around 500 to get rid of the ambient light. The flash's where triggered over pc cord or an optical trigger. And the pccord is just frustrating, you need to check the connections all 2 minutes

ok now after trying a couple of hours to remove the 'scratch' in the picture I gave up. i'm just not able to remove it and all what happens is that the picture looks fake. i tried dodging and cloning.
