I don’t post my work from my volunteering for theatre photography with a school, but I can show you our test set up. The goal when working with the tech crew is to make others realize that while the subject may be young, they are trained in a skill that is a bit more complex than normal skill and deserve the respect that comes with knowing that complex skill. You can train a chicken to play tic tac toe, you can’t train a chicken to operate stage lights and effects.
Part of it involves a little trickery, as I know we can’t get access to the tech crew equipment, but I do have access to my equipment, and they do have access to some easy to grab items, so I mix and match everything. For starters, for this year’s set up, I plan on using one of my strobes that conveniently had the stickers fall off, but it sure does look like a stage light to the untrained (or basically everyone who has never actually seen a stage light up close). I plan to also have the tech crew bring any headsets, clipboards, or scripts they may need with their job with them. It adds to the professional look and having a tool of your trade, even if it may seem insignificant to you, makes it easier to relax and do the photo.
For the shot itself I go with a speedlight up high in back pointed down as a hair light, a strobe just off to front with a square softbox and a grid on as the key light, and a strobe just off to the side with a long softbox and a grid as a fill light. I throw in the previously started strobe and a step ladder for props/seating and the rest sort of works itself out. A lot of poses can be pulled out of this set up which is good because tech crews tend to be somewhere between 5 and 10 people.
