I was hoping someone could point me in the right direction. I am trying to begin organization of a large collection of glass negatives. These range from images of space food, training, launch prep and in flight.

I'm trying to figure out how to build an easy lightbox so they can be viewable. I haven't had much time over the past several years to dedicate time but things have changed. If anyone knows of similar items please let me know. Thanks.

There are several backlit photo frame projects available online that use cheap, deep sided photo frames and LED strip lights.

I have previously done something similar that incorporated the thin film diffuser material sourced from an old LED TV. This material hides the shape of the back light.

I also found that different images need differing intensity light to best render detail. Some need very low light level, other need more. This can be achieved using dimmable lighting. There are many sources for this online, Ikea seems to be a popular global supplier.
