Double exposes pictures?

Question

What is it? Also how do you do it, I know it creates great details to pictures such as this artists work http://inae.deviantart.com/.

I love the style a lot, tell me how I can do it in my own way :)

Answer 1

Nice link, 4mat.

First, you need to find out if your camera can take double or multiple exposures. Your Owner's Manual should tell you. Unfortunately, most film and digital cameras don't allow more than one exposure at a time. I currently own 2 film cameras with multiple exposure capability - the Minolta SRT-202 and the Minolta XE-7. With the 202 I have to change the ISO. The XE-7 has an EV dial so its my camera of choice for multiple exposures.

If you have a film camera that doesn't allow double or multiple exposures you can try this, called the "3 finger technique".

Make your first exposure.

First, depress and hold the film rewind button.

Second, hold pressure on the rewind knob.

Third, gently advance the film wind lever to set the shutter. If you feel pressure on the rewind knob, as though its trying to turn, stop. Continued pressure may damage your film.

Even when successful this technique does not guarantee perfect registration.

In the article referenced by 4mat you are told to use -1 EV for 2 exposures or -2 EV for 4 exposures Use -1.5 EV for a triple exposure. If your camera doesn't have an EV dial you'll need to change your ISO. If you're using ISO 200, double it for 2 exposures (400) triple it for 3 exposures (600) and if making 4 exposures quadruple it (800). Then compose, meter as you normally would, use the "3 finger technique" and take the next exposure.

NOTE: Don't forget to set the ISO back to its original value when you're finished with your double or multiple exposures.

If using a digital camera you'll have to check the Owner's Manual.

The wikipedia article also mentioned using an editing program to create the effect of multiple exposures.

A much better explanation can be found at AIRC-Adorama Imaging Resource Center. Click on SFX Photography. Elinor Shecker-Orel is an instructor at the New York Institute of Photography. Her explanations are clear and consise.

Answer 2

Now days, of course, this can be done much easier, and with greater control in applications such as Photoshop.

Photography "purists" will, however, rightly point out that this is not a true "double exposure," an appellation that they MIGHT extend to the process if done in a darkroom. (or maybe not) But "purists" often insist that the negative's image should NEVER be cropped.

Me? All I care is for the resultant image, and the process to reach this goal should be trasparent to the viewer.

Who's with me, on this?

Answer 3

double exposure is the exposure of a negative twice instead of once. This means that light affects the negative on the two separate occasions. Allowing for different images to be recorded on the negative. this can be done on certain cameras by not winding the negative forwards after an exposure. try this wikipedia link for more info
