FB prints can be prevented from curling by soaking them in a dilute solution of glycerin or similar humectant before drying. Try 2 ounces of glycerin and 30 ounces of water. Depending on your average local humidity the amount of glycerin can be altered.
A question: The altering, would it be more glycerin for areas of less humidity or less glycerin? Will try this as soon as I can find glycerin, maybe the drugstore.
I photograph things to see what things look like photographed.
