Can someone clarify a point for me ?
Are double exposures allowed under basic editing rules?
My interpretation is that it is fine provided it is done within the camera..Is this correct ?
I was intending to submit a double exposure for the "zodiac" challenge but left things too late...plus the pic required some spot editing which ruled it out.

Thanks,
Gordon

How many digital cameras CAN do double exposures?

The best I can do is a 16 second exposure with two flashes.

a double exposure has nothing to do with the shutter speed.

its overlapping two different photos to produce a weird combination or effect.

like a house on top of a pond or something like that. i have done it in a darkroom, by modifying the negatives, and dodgeing and burning the exposure to get a clean transistion.

EDIT: i have also done it with the 35mm camera by marking the rewind dial and then shooting a shot, rewinding to my mark, and shooting again, this is difficult as you have to be careful not to over expose, and you cant see the results until you develope the film.

EDIT II: with a long exposure and a lense cap, i suppose you could change the subject while the cap is on, and then remove it, but you wouldnt get another chance to focus so they would have to be the same distance away or you would need a large f#

There is an option to do this on the Fuji 602z and I tried it for the first time last night...wasn`t too bad but I don`t think I`ll be using that option too often.

Some film based multiple exposures (9 per shot)

I understand this. I've done double exposure with film cameras many times. What I meant was that the only way I can approximate a double exposure with my digital camera is to have two seperate lighted incidents (separated by darkeness) within the time allowed by a single exposure (aximum of 16 seconds on my camera).

What I was wondering is, are there any digital cameras that will actually allow you to take two separate exposures over the same file? If so, does this fall outside of the DPC rules on a single picture?

my Fuji S602 does, so i'd imagine that the other fuji cams do as well.
