I have been asked to take some product photos of various scientific lasers.
Most of them will just be simple shots of the boxes on a white background but I will also have to do an 'action' shot a bit like the one below. The laser produces a white beam that can be split into the full colour spectrum when it goes through a special prism.
I have never photographed anything remotely like this before and I want to get it right. For example it would be nice to minimise the amount of reflection on the laser 'box' itself. I will have to do this in an empty laboratory as I will not be allowed to take the laser off site.
In terms of gear I've got a nikon d300, a selection of dx lenses (35mm, 18-200mm, 14-24mm) and a decent tripod.
How should I approach something like this?
