A couple days ago I posted an image of some lamp batteries. This image shows the charging unit that was used for those batteries. It is in the lamphouse of the Nordegg Mine Site. I don't understand much beyond basic wiring, so I'm not sure exactly how this unit functioned. It appears that there were means to control the voltage and duration of the charge.
This photograph was taken on a sheet of Kodak T-Max 100, 4" x 5", rated at 80 iso and developed in 510 Pyro. This sheet was in a batch of 20 sheets that I developed on December 19th. I gave the batch normal development, which was 1:100 dilution for 8:00 minutes at 24C.
I shot this image on July 29th 2025 at about 1:15 in the afternoon, during one of my many private tours of the historic site. I used my Ebony SV45Ti view camera and a Fujinon 180mm lens. Due to the very low light levels in the old lamphouse, the exposure was very long; 60 seconds at F20.0.
