About 3 years ago fellow film photography enthusiast but also wedding and wet plate photographer James Pearson described how to fire a modern-ish flash using the weird 2 pin flash poles on a classic Crown or Speed Graphic large format press camera.
I had always meant to do this (3 years ago) but I finally gave it a go and it was actually pretty easy. All you need to do is grab one of these wee double wire connecting brick things (it has a name I’m sure) and attach each Crown/Speed Graphic flash-sync pole into it, strip a PC flash cord and screw the wires into the other end (not sure if it matters which way round) and hook the PC cord into a flash gun that has a PC port and you’re done.
All that’s left is to make sure the flash mode on the shutter is set to X, if your shutter doesn’t support X-Sync then you’ll need to create a module that’ll delay the signal reaching the flash but that’s way above my pay-grade that’s for sure.
My next step is to buy or fashion a plate to sit my flash on using the tripod screw threads under the camera.
Here’s a wee video to hopefully make it clear.
