I have a box of the white film sitting on top of my printer right now... I have yet to open it because when I emailed pictorico, they told me that the film is opaque and will not shine light through. Are they telling me misinformation? Also for the price, a roll of 100' of the Epson trans is about double the price of 20 13*19 sheets of pictorico
It's opaque, but bright lights behind it will illuminate. I've used it for digital negs when printing lith (although it wasn't worth the extra exposure time vs. OHP).
