tom lavin Posted August 31, 2005 Share Posted August 31, 2005 I've never seen this topic addressed, and I don't know of a digital camera that can make a double exposure. I'm just curious as to why not. I can only surmise that noise could be a problem with a bad exposure (and a good double exposure is just two bad exposures sandwiched together). It just seems to me that a digital camera can do nearly everything you can imagine - except that............Tom Link to comment Share on other sites More sharing options...
alexdi Posted August 31, 2005 Share Posted August 31, 2005 None will do double exposures. It wouldn't be technically impossible, but nor would it have much point. Any decent image editor can combine two pictures with far more flexibility. DI Link to comment Share on other sites More sharing options...
bellavance Posted August 31, 2005 Share Posted August 31, 2005 Quite easy to do in Photoshop, and you control everything. Pierre Link to comment Share on other sites More sharing options...
ole_hjalmar_kristensen Posted August 31, 2005 Share Posted August 31, 2005 What would be the point? You can easily create a double exposure in an image editing program such as Photoshop or Gimp. Link to comment Share on other sites More sharing options...
jayhai Posted August 31, 2005 Share Posted August 31, 2005 using the right settings and multiple flashs you can create a "digital double exposure", but it is not like film. Link to comment Share on other sites More sharing options...
jayhai Posted August 31, 2005 Share Posted August 31, 2005 does this count?, this was done in a dark room with two flashes.<div></div> Link to comment Share on other sites More sharing options...
tom lavin Posted August 31, 2005 Author Share Posted August 31, 2005 I understand this can be done in Photoshop - I've done it many times. However, there's a completely different mind set in doing it in Photoshop than doing it in the field. The experimental and unknown output that is fun to do with film it not an option with Photoshop. I was more curious about the technical reasons why is isn't or can't be done..........Tom Link to comment Share on other sites More sharing options...
jhall Posted August 31, 2005 Share Posted August 31, 2005 Well, technically still one exposure... But PS has all but eliminated the 'need' for double exposures. Link to comment Share on other sites More sharing options...

jayhai Posted August 31, 2005 Share Posted August 31, 2005 It cant be done in the tradional sense because, there is no way to work on the same film exposure in a digital camera, other than the example I gave above. Photoshop was only used to adjust the curves in that photo. The multiple images of the subject were done in the same exposure. 15 seconds a darkroom and a flash.

ralph_jensen Posted August 31, 2005 Share Posted August 31, 2005 . A FIRST! This is the first time I've ever seen three simultaneous responses to a post on photo.net (all at 8:46 p.m.). Wow. Sorry about the OT nature of my response; I do agree with Tom about the unpredictability and spontaneity of doing it "in-camera," not knowing exactly what the effect would be.

dmitriyk Posted August 31, 2005 Share Posted August 31, 2005 The Nikon D2x can be used to create multiple-exposure images in-camera. Link to comment Share on other sites More sharing options...
kaden_n Posted September 1, 2005 Share Posted September 1, 2005 I may be wrong, But I believe the Fuji S2 can do double exposures... Link to comment Share on other sites More sharing options...
ky2 Posted September 1, 2005 Share Posted September 1, 2005 Kaden you are right. The S2 can do more than double exposures. Link to comment Share on other sites More sharing options...
conrad_fischer1 Posted September 1, 2005 Share Posted September 1, 2005 Notwithstanding the answers that say that the Fuji and the Nikon can do double exposures, here is my take on the subject. In film the "sensor" is a chemical reaction that is cumulative, or analog if you will. Teh more light that you add the darker the spot becomes. And the process is additive, if I open the shutter once, the light reacts with the film, if I open it again, it adds to that reaction. In the digital world the sensor reports, as a numeric value the intensity of the light that strikes the sensor and then it resets for the next exposure. To get the double exposure the sensor would have to "remember" the last shot and add the value to the new shot. Entirely possible I suppose, but a bit of a problem for the programmer. All of this comes from someone with just enough knowledge on the subject to get in trouble with.I do appreciate the question, I have some rather old photos of my family that were accidentally double exposed and they are priceless. They accidently juxtapose people in time and space that would be impossible to compose. Link to comment Share on other sites More sharing options...
mormegil Posted September 1, 2005 Share Posted September 1, 2005 You can emulate a double exposure in Photoshop most correctly by overlaying images with the layer set to screen. It's additive, just like a real double exposure. That means your background will still have to be half exposed each (best to do at least one with a black background).

phule Posted September 1, 2005 Share Posted September 1, 2005 << None will do double exposures. >> Not correct. Fuji S3 Nikon D2X Pentax *ist D All three do multiple exposures in-camera. Link to comment Share on other sites More sharing options...
alexdi Posted September 1, 2005 Share Posted September 1, 2005 I stand corrected. But then, I considered it so trivial either way I didn't bother fact-checking that one. DI Link to comment Share on other sites More sharing options...
