The idea behind the light table is simple. Things look really great if the light is passing through them. As opposed to light being reflected off them. This is why slides look so good, this is why we love vitrage windows in churches.
A light table is the perfect way to inspect slides, negs and to do some really interesting art.
This project by Felix uses an old desktop (from when desktops were actually made from wood and did not have any chips in them), however, a similar project can be made with more temporary means which are great for a weekend project. I’ll discuss this towards the end.
