Re: 40cm Iwagumi I use my 3x24w T5 luminaire, placed straight on top of the tank. It's about 1cm from the water. I'm using 2 8000k tubes and 1 6400k. The tank light gets turned to illuminate the white card background.
The camera is a Canon 350d, and I use the standard lens to get the wide angle (I don't have a wide angle lens yet). Camera was set to manual, ISO 200, Focal length around 25mm, aperture around f8, shutter around 1/50-1/60.
Then I balanced the hairdryer so it gives decent ripples, while juggling a black blanket to stop reflections and trying to take a photo! |
