barrel lens

[Robert Choi]

I have read about people using barrel lens in cameras like speed graphic or sinar that has an auto shutter.Iwonder if there is other method to use barrrel lens. Any input will be greatly appreciated.

for longer exposures (a few seconds and more) you just remove the lens cap and replace it. long exposures are really not that uncommon in large format photography. if you look for example at john sexton's work you'll see that almost all his exposures are several seconds to several minutes long. even in daylight with slow film and a nd filter it's easy to get there.

for studio work with flash you could make sure the scene is dark enough, remove the lens cap and fire the flash manually.

I used barrel mount lenses exclusively on my 8 x 10 Deardorff. I installed a Pac kard shutter inside the camera and routed the air pipe out the side, well lightp roofed. The shutter had a pin that would operate at 1/25th when pushed in. Pulle d out it was "B" there was also a set of sync contacts for X sync. Worked fine.
