Inquiring about in camera effects

[pinealfilms]

I am a inquiring about how one would expose for a triple images on one negative, and to do it in camera. If anyone may have some input let me know I am shooting this this weekend 5-6 & 5-7.

The exposures will accumulate. So if you are exposing three times, you need to reduce each exposure by about 1 1/2 stops or 1 2/3stops.

 

That's if you have a normally lit background or areas that will accumulate. If it's a subject against a dark or black ground, that will be in a different place in the frame for each exposure, then you need to expose it normally.

Not sure if you mean three seperate exposures on your original neg or three seperate images (triptych)?

If the first applies, Dominics suggestions are sensible, if it's 3 *panels*, then you are looking for a series of 3 way aperture mattes - probably a little difficult to track down or have fabricated on short notice -that are inserted into the aperture plate on some 35mm cine cameras.

 

Another way depending on your shot, is to set it up using strategically placed strips of mirror to block your locked off shot- this can be very fiddly to execute in one go. I have also got the grip dept. one time to construct a *jumbo* matte box out of heavy black card and gaffer tape with flap down panels at the front. Works ok, but a W/A lens set at f/16+ helps for sharp edges and you hope the wind isn't too strong on location.

 

cheers,
