Multiple Exposures

[IanG]

Quite a different technique



This is best described as a fragmented exposure (a fraggie) a technique pioneered by John Blakemore in the UK in the 70's or 80's. The whole exposure is made up of multiple exposures of varying lengths.

This was a long exposure using a green filter on quite a windy spring day, the total exposure was a few seconds at f22 or maybe f32 but I made that up with a number of shorter exposures some at 1/15. others slower down to about 1/2. It gives images that are quite different to the continuous blur a single long exposure would give in areas of movement.

Quite a different technique.

This had not occurred to me before. I suppose this approach is best suited to a self-cocking shutter to avoid any camera movement from manual re-cocking. My big Ilex No. 5 is self-cocking, so maybe I'll give it a try. Although, on a windy day like that keeping my old rickety 8x10 from moving between exposures--not the shutter--would be the problem.

5 exposures at 1/50th

the camera i have only has a 1/50th shutter speed and a T speed ..

It's not something I do very often but it's always been with a Copal #0 and a Sironar or Grandagon. It takes very little to recock the shutters.

Ian,

I suppose that's true. Lately I've been shooting with older Compurs and the force required to cock those would fractionally vibrate the camera out of alignment for the next shot, but my newer Copals require much less effort to reset.
