The ideal slide or negative copying environment for ShotCopy is a shaded light source in a dark room. In many cases this is not a practical environment. Here is a method to help eliminate your reflection problem.

In the photograph to the upper right you will notice that you can create a light tunnel between the slide/negative holder and your camera lens. This is done by setting up the proper distance for the image to be focused and copied. Then cut a strip of flat black construction paper that spans the distance between the slide or negative and the lens. Fold the sides of the strip into a rectangular box that matches the outer dimensions of the slide/negative holder as shown in the picture.

Also, you hand can come in handy as a light shield if you find a light leak just before you take the picture.
