p.1 #1 · Day two with the stopshot


This has to be one of the most difficult shots I have ever tried. There are so many variables that come into play but I am learning a lot so that makes it worth it!
Going to go take images of the set up now.....





Worlds smallest aquarium

  Canon EOS-1D Mark IV    1/125s    800 ISO    0.0 EV

Here is the setup. Sorry about the lousy quality of this shot but I am working in a small space and it was hard finding a spot to shoot from where I could get everything in.

A single 550EX flash at 1/128 power fired through a diffusion gel directly at the image of the tang. 1DMKIV with a 120mm Mamiya macro lens, f/11, 1/125(shutter speed doesn't matter for this) A stopshot controller for the timing of the drops, shutter, and flash. Timing is everything with this and there are several variables that all come into play. Getting the drops sized and spaced consistently with the amount of time the valve is open and the time it is shut between drops. The amount of time between the drops falling through the sensor and the shutter opening and then the amount of delay before the flash fires. Adjusting any one of these effects all the other timing. I also figured out that the only way to catch the drop with the image inside sharp is to use a single flash unit. There is just enough delay between two of them to cause the drop to streak some. I'm sure I could probably work that out with more testing so I would be able to shoot at lower iso's.

Just think of the variables if you were trying to get a live fish's reflection!

THe problem with shooting a live fish is the glare off the glass! I had to shoot this tang with a rubber lens hood pressed up against the aquarium to control the glare and reflections. But, if there were a way to do it, I would love to try it out!

Ideally, fish in an aquarium should be lit from above i.e. from inside the lid. If that is not possible, the flash should aimed be from a position about 45 degree to the axis of the camera. Flash from the camera position will always give a sharpish refected image of the flashgun firing, such that masking it out may be essential, although a long enough focal length (telemacro) might work by framing to exclude the reflection.

Great catch Ron. Techy looking setup... Bet it makes life easier though
