Diffuser for DIY scan light source

[Gihl_220328_0001] This is the lighting setup I use when capturing 4x5 black and white negatives. (1x2 multiple captures). I use a 3mm thick acrylic plastic sheet. Although you can’t see it in this photo, I put a rubber pad between the acrylic plastic sheet and the LED panel. I use 2 pieces of Tru Vue museum glass. When I scan, I turn off all lights in the room. Also, I scan 4x5 films with a large black mask.
