Dig out and dust off your old light table and put it to use as backlighting for macro subjects. When I started in photography in 2001 I bought a few nature magazines and noticed all the pros were using Velvia slide film, so I used slide film which required me to buy a light table to view the slides.
I only shot film for three years and then made the change to digital. The light tables has been dark until I found a use for it. It works great for backlighting which creates a special look to your images. You need subjects that are somewhat transparent for the best results.
Above is a group of Beech leaves I arranged on the light table and below is a Turkey feather I found in my local park. I added a drop of water to the feather to add a little interest.
