I am testing new photo tanks. The one that these photos were shot in is a little different than most that I make. Most have a painted black back and a frosted glass bottom to diffuse light. The biggest problem that I have is cutting down the amount of light that I throw on a tank. So this time I painted the back, sides and bottom first with frosted glass paint to give it a texture (less glare) then with white paint. The tank is 2 ½ gallons…about 12” across and eight inches high.
I used four Nikon SB-900 flash units on the tank. One
below, one on the back and two on the top.(picture attached) So I end up
shooting at 1/320th of a second at an extremely low ISO and very
high aperture (@f32). The amount of light that these four lights throw on that
small area is amazing. Any one of those flash units could illuminate a
subject twenty foot away.
If I have to cut even more light I made a couple
additional individual pieces of ¼” plexi that I painted in various
depths (white to grey) so I
can add that (one layer or more) to bottom or top to cut back light. If
you are familiar with photo terms, the effect is like that of a neutral
density filter.
I wanted the tank to be
versatile enough to shoot all kinds of fish. I have another piece of
glass cut to the inside dimensions of the tank and painted black. I can
move the back wall forward and position with some channels that I made
w/small
industrial suction cups. This just to keep some control over the
fish. If the fish goes too close to the back and hides, I adjust the
movable wall to keep them in front of the tank. I also cut two pieces
of stone tile that I can lay at a diagonal
from the front of the tank to the back…to photo catfish and the other
bottom
dwellers.
Next I filled the tank with two small Hogaboomorum
to test the lighting. Here's the set up. The small flashlight on the
top helps me to focus.
The results were OK. But the fish would hug and hide. So I went and got the larger male from the tank and added him. That got everyone moving. Here's two shots.
Next I added a net full of half inch P.
fredrichsthali "La Cieba" fry to try the macro. Wasn't sure what to
expect. One of the challenges of shooting macro is the depth of field.
Less light means you have to open the aperture. A wider aperture (lower
number ex. f3.5, f4, ) Whe you shoot something this small, a higher
aperture gives you bigger depth of field. Here's two tips. The farther
back you can get and shoot, the better the depth o field...the
closer...like with macro, the shorter (less of the area will be in
focus). The other tip is to "zone focus". In this case, rather than
focus on the exact part of the fish I wanted in focus, I would move down
the body a little. This assured me that I would get not only front,
but back in focus...in most cases...becasue of the DOF range.
Considering the bubble at the top of the tank.
Some portraits..remember, these fish are all 1/4 - 1/2" in size:
Here's a little guy that was so excited...he crapped himself.
Not wanting to stop here, I swapped out the Freddies for some P. managuense "Xiola" ...these 1/4 inch and smaller.
I put some decapsulated brine shrimp in with the fish. If you have ever used it, you know it's very very small. IN the photos they look like regular pellet. What I though interesting is that there is so little color on the fish that you can actually see the brine shrimp (color orange) that they are eating.
Couple other interesting observations...if you take a close look at the fish, it almost looks like their skin is comprised of dots. I am assuming that the color of the fish is still developing. Perhaps the chromatophores (pigment) of the fish is still developing. The other is that the eyes are disproportionally large to the rest of the body. Maybe natures was of giving the easily preyed on fry a better chance of seeing it coming. I back this up with seeing tanks full of scattered tiny fry coming together as a group when they see me approaching the tank...waiting for food. What they see, who knows...but without a doubt they react.
Hope you enjoyed this. If you have any specific questions about the setup, I'd be glad to answer what I can. I hope this translates well into Turkish

Yeni bir fotoğraflama tankı yapmış. Arkayı ve yanları boyayı alt camı buzlu cam yaparak yansımayı azaltmış. Özel makine ve ekipmanla yakın plan çekimler yapmış. Sonuçlarını da fotoğraflardan görüyorsunuz. Sondaki yavru balıkların boyları yaklaşık 0.5 cm ile 1.5 cm arasında değişiyor. Üstte yüzen yemlerse kabuksuz artemia ve minicik olmasına rağmen resimlerde kocaman çıkmış.
Makine ve balık isimlerini yazısını inceleyerek görebilirsiniz. Özet olduğu için uzun uzun yazmadım.

Dostum balıkların süperde ben videoyaya eklediğin parçaya daha fena takıldım... :)
