Good day. While reading another topic and following some posted old reference links I came across the use of zinc metal, when inserted into a batch of too old, too red collodion to decolorize it. This was found in "Notes and Queries", the "Restoration of old Collodion". This note provided by a Mr. Hautes Pyrenes Luz, which appears to be more likely a nom de plume. It is a direct reactio

Hello. I am new to the forum and only a bit more familiar with wet plate photography. My question is this?
