The traditional method of preparing high quality projection slides of one's best electron micrographs was to “print” negatives onto Kodak 2″ x 2″ emulsified glass slides using a standard enlarger fitted with a reduction lens and then to tray develop the slide to the desired contrast. As A. Kent Christensen pointed out in the June/July 1994 issue of this publication, the cost of 2″ x 2″ slides has become prohibitive. In any event, I always found adjusting the reduction lens on the enlarger to be a major hassle and searching for the correct exposure and developing times to be a ffustratingly inexact experience with much plate wastage.
