light integrator – Koraks tinkers

Adding it up – A new multi-channel UV integrator

I have been using a (DIY) integrator for a while to get consistent exposures on my alt process prints. Recently, I grew unhappy with the buggy nature of the device I had built, so I made a new version using stuff from the parts box.
