I have a use for a pellicle mirror, about 4" x 5" in size. It's to be used to shoot through at 45 degrees while also acting as a light reflector. I already Googled it, and got a hit on using food wrap as a replacement for the pellicle mirror in a Sony camera; where it worked quite well by all reports. I figure that its use in front of a sensor might be more demanding than simply pointing a lens through the stuff. Another suggestion was to use the protective film used for phone and tablet screens. But it seems to me that a thinner film would be better. So, has anyone tried shooting through clingfilm? Or any other readily-available thin plastic. BTW. I know this isn't strictly a beginner question, but I thought this forum might attract the most replies. There's also one-way mirror film sold for coating windows, but this might be too reflective for the above purpose. Could be useful for healing up the shooting hole in a light-tent though.
