Fish

Taking photos through an aquarium is difficult. The lens must be directly parallel on the “glass” to prevent “fringing”, or the rainbow effect you get from different frequencies of light refracting at different angles. Additionally, there is spillover from the flashes themselves. On old plastic (as seen here), every scratch or imperfection glows. You can get around this with little things by placing the lens and/or flashes directly against the glass and shooting such that no light spills onto the surface you’re surfing through. This is harder with bigger animals like this fish. Here, I had to set the flashes to a fairly tight field of view and hope the fish didn’t move too much as I set up and took the shot. As you can see, it could have worked better. It also helps to clean the glass. The older it is, though, the less well that works. What I need to do it better is some sort of angled “snoot” that allows for better light blocking. I have started some experiments with ThinkingPutty to make some of my own in the field. They’re working well, but as you can see, I need more practice.
