A3 paper seems a little flimsy in terms of its ability to withstand humidity etc, so I'm going to try a custom cut piece of flat acrylic light diffuser near to the objective of my C9.25 instead (probably with a small handle or something on it to make it easy to put on / remove). I have some on order from eBay and will cut it to size on my scroll saw if it ever arrives  I'm hoping that it'll diffuse the led panel light nice and evenly, and be long lasting. Fingers crossed! It's an ongoing experiment |
that's a great idea and the same thought crossed my mind about using acrylic after some of the paper I had got wet due to dew.
You can also get ND gel film that video folks use in their movie making. 0.9 or 1.2 is fine.
That's a wonderful diffuser.
