Like many of us who have been at photography for a while, I have lots of slides. I do not own a slide scanner because I work at a pro-level photo lab and can have them scanned at work. However, when I need something quick and dirty I have found this method works well. I just put the slide on my light table and photograph it with a macro lens. My tripod has a center column that swivels out to a horizontal position so that the camera can be pointed down. Here is one I just shot, as someone asked for it on a zoo forum I frequent. Taken with 5d3 and Canon 100 2_8 macro (pre-L version).
