Unintentional Double Exposure

Yep, a double exposure, in camera on a digital point and shoot+.

I was taking a series of timed exposures of the city and decided to swing the camera around between shots, but mistimed it so the move was mid-shot, resulting in a transplant of the CBD onto South Bank ;)

Taken during the 30th Sept Brisbanites Flickr meet at Kangaroo Point Cliffs.

    marvelous! i never thought yu could take a double exposure with a digital, but yu have discovered the way.

    The image looks impressive. I didn't know you could do this.

    Seen in my contacts' photos. (?)

    Thanks Greg and Alexandra.

    It's got me intrigued now, I'm thinking of doing some experiments with long exposures and a piece of black card to cover the lens mid-exposure.

    the clever bit is being able to do it again !!!

    it is an excellent effect.

    Helen, I reckon that would be quite repeatable. :)

    Thanks Brian!

    it's basically fairly similar to open-flash photography. i used to do a lot of it in caves. you put your camera on a tripod, open the shutter and "paint" the subject with multiple flash shots over a period of several minutes. between flashes yu have someone cover the lens while yu walk around to your next position for flashing. we used to cover the lens by holding a caving helmet in front of it. black card would have been better but the flash-person(s) used dim lighting to get around so it was ok.

    i know good digital cameras have a B setting but usually they do not accept a cable release so i don;t know just how one locks the shutter open in a vibration-free manner. remote control perhaps?
  • David de Groot said:
    Greg, all the current release Canon dSLRs have a (buy separately) cable release, although there are plans on the interenet so one can make ones own. I believe several models also have an infrared remote too, but the infrared port is on the front of the camera, making it only useful if you're also in front of the camera.
  • The Central Scrutiniser said:
    the shutter buttons on dslr's are not suited to screwing a mechanical cable release into so i am presuming that the canon cable releases are electronic in nature, fitting into a socket somewhere...?
  • David de Groot said:
    Sure is Greg, here are a couple of DIY sites detailing the exact remote setup:



    When I can eventually afford a 400D I'll be making one of these little guys :)

    They don't have plans for DIY flash cords, do they? The flash cord for Canon digital is a design atrocity. Curly, like an old telephone cord, it stretches only to a metre or so, and the curl ensures the flash unit always pulls back towards the camera.

    I agree, double exposures with card should work fine.

    Ian, I haven't been able to track down DIY links for that, but this site provides show adapters and a 3m straight connecting cord, which might prove a better solution than the coiled cord.
