Untoned salt print from calotype.
Printed 31 October.

Stain in upper left corner appeared on the back of the paper before printing. It came through the paper and caused some fogging in the unexposed area. Possibly there was some contamination on the plastic board I sensitized the paper on.

This paper was originally prepared in June 2019 with rice starch and salt. Strathmore 500 plate finish drawing paper.
