I like to eliminate as many variables as possible and make the processes repeatable
Years ago I bought a light table from GEPE in 4x5 format for a project of measuring the color of foods in real time during processing
After the project was over the equipment became surplus and I kept the light table
That has been a good light source, since it is constant in color and luminosity (when using a 9V adapter ) and is the one I used for copying my grandfather's glass plates. BUT it is showing signs of age, and some areas are darker than others.
However, while preparing for that I got a
LED light source from Amazon (it was less than $10) which was not good for the glass plates because it iluminates in "stripes". These days I tried a heavy paper diffuser (i.e. a cardstock sheet) over it to even out the light and it works fine as illumination for the slide copier
Exposures are in the order of 1/8 to 1/2" @EI200 depending on the density of the slide but since it's all static that is no problem
