Can you tell what type of photos these are?
A tintype (left) can be tested with a magnet. A daguerreotype (right) can be viewed as a negative image in the right lighting conditions. Some photos require lighting and 10x up to 120x magnification to be identified. Monica Mull, owner of Art CPR, gained expertise in dating and preserving old photos from Alice and Jae of the Image Permanence Institute's September class, hosted by the Chicago History Museum. Located at the Rochester Institute of Technology, New York, the IPI has created a new website tool to help identify photo processes. See if you can use the site to identify some of your old family photos! Or make an appointment with Art CPR to identify and conserve your family heirlooms.
