Back Lit Tracing Screen

I’ve been taking pictures of devices for a course that I’m writing. I’ve been fretting about the way that it is hard to avoid shadows underneath components and wires. I wondered if a tracing screen would be any good at eliminating dark areas on the background. You can pick them up for not much money nowadays, so I bought one.

It’s not quite what I want, as you can see above the light is a lot of points rather than even. I’m trying to find a diffusor that give a nice even spread. However, this does mean that if I ever want to trace some pictures I’ve now got the perfect device.
