Processing black & white film at home is easy. You just need a changing bag to load the film into a tank in darkness, and the rest can be done in the bathroom with the light turned on. The chemicals for black & white are normally used at 20°C but can be used at roomContinue reading “Processing colour C-41 films at home”

Baby, it’s cold outside
I posted a few months ago to say that my server wasn’t a massive fan of the high temperature in my loft. Well, now it’s too cold. The UK has had a bit of a cold snap lately.

I eventually found the blog of Tollef Fog Heen, who had managed to get his TEMPer to work. Unfortunately hisContinue reading “TEMPer USB thermometer on Linux”
