I managed to get my hands on a roll of Shanghai GP3 100 B&W film and shot these in studio with Sarah. My Mamiya C220 is a fully manual TLR that doesn’t have a hotshoe. Instead it has a PC socket with a M-sync / X-sync switch. Using a cable, I can connect the Mamiya to the PC socket on my radio trigger and use it with studio strobes. I was rather pleased with the results.
