I was asked to do an exhibition of some of my latest photos. So far, no problem, but as a highlight I would like to present one photo in a backlit frame. The output size should be something around 2m x 1.5m.
What material is best to print on so one can't see the backlight? Glass or some kind of slide?
Should a slide be glued on an opal glass pane? Such a pane could help to transmit the backlight in a more areal fashion, I think.
What is the best backlight for this? White neon tube or white or even blue LED?
All this seems quite similar to what one knows from bus shelters or those big ads, although in this case the printed picture will be presented indoors.
