210mm f/45; 13.7 seconds

The last b&w 4x5 sheet film to be exposed and processed at a commercial lab in the US? Apparently Dodge-Chrome - who has developed my sheet film for years - has ceased doing chemical processing. What now, Brown Cow? We're on a septic system, and the internet says don't dispose of film effluent into one. I believe it. Let the liquid evaporate, dispose of solids at the appropriate waste authority?
