In this season's finale of Tin Questions, I get to sit down with a chemist turned wetplater turned wetplate chemical supplier, Brian Cuyler. Starting out in collodion at the beginning of the recent renaissance period, Brian used his background in chemistry to investigate some of the historical recipes that we all use and tweak them to produce collodions specialized for different situations. Seeing a gap in the market for these craft collodions, Brian started his own wetplate chemical supply business, UV Photographics. Listen in and hear why you should always "Respect the Chemistry!"
