I used my Canon 5D and the Canon 100mm Macro lens to copy the 35mm negatives in this gallery.
The light is a full spectrum compact fluorescent with a diffuser glass between the light and negative. The light probably does not need to be a full spectrum because a lot of color adjustment is needed anyway. I use it in low light conditions to eliminate any reflection off of the negative.

The original photos were taken with a Canon FTb or AE-1

Comments or suggestions on the process are welcome.
