SP-8x10+: bad news, good news and patent pending.

What's been happening?We've shot more 8x10 film in the last few weeks than most people do in a year! Unfortunately, most of it was the same boring shot of our building's door. The freshly painted, light gray door faces south and is evenly lit by the Colorado sun. It is one of the most challenging subjects we've ever found. We've learned a lot.

People have asked about using a water bath and the SP-445.  Bear in mind that the SP-445 is molded out of rather thick plastic. This is a much better insulator than a highly conductive steel tank or even the comparatively thin walls of most other plastic tanks. (Some of which are surprisingly thin.) But how much better? Here's an exciting chart that describes the thermodynamic characteristics of the SP-445: The temperature in the SP-445 will shift by less than 3 degrees over...
