Hi guys, I'm new to the forum and pretty new to photography. Glimpsed this sub-forum and realized I had such a question. After seeing some pictures using this technique I've grown interested in it and was just wondering how its achieved. I use a canon EOS 450D and a minolta 404si film slr (which is out of production). Is the technique the same for both film and digital or does it differ?

Would appreciate any help, thanks in advance!
 
I don't think that you can do a double exposure with most digital cameras. I say "most" because I'm pretty sure that I read that it was a feature on one model but I can't remember the details.

I never tried it with film but I assume that if you're going to expose the film twice you'd have to share the light between the exposures, for example, if the shot should take 200/sec to be correctly metered you'd expose the film twice at 400/sec each?

I think that with a digital camera you'd have to do it in photoshop rather than in camera?
 
My d700 has a multiple exposure setting, I presume that's the same thing?? I'm sure some of my other nikons had it too, but I never used it.

It overlays the next shot on top of the new one, maybe even more than 2 shots, I'm not sure??
 
Ok thanks guys, I was wondering if it was achieved by using the continuous shot mode that you guys have mentioned but I think that just takes separate shots in quick succession? MWHCVT, thanks for the recommentdation, so is it purely a software thing or can it be done when you are out taking pictures by doing something with your camera?

edit: I seem to have misunderstood you TCR, that seems like just the thing I'm talking about. So my canon eos 450d would not have such a feature as its not a nikon?

The camera I was thinking about was a Nikon so maybe they're the only digital's to offer it in camera?
 
I dont know about the canon, but the D700 has a setting in the custom menu called multiple exposure. It allows you to shoot up to 10 shots on the same "frame".

Continous shooting as you said is for high speed shots.
Im pretty sure my D90 had it too, so it might ust be a Nikon thing. Not something Ive ever used so dont take much notice of it.

Yes, the D700 can combine from 2 to 10 shots into one image.

Not yet tried it, myself, but it is probably less trouble than doing it with Photoshop etc.
 
Nope, no option on the 450D. It really depends on the picture you are taking, if its a dark scene theres afew ways of doing it but only if you are taking one pic after another, ND filter, long exposure and a piece of card :) also read up on second curtain flash but simplest way would be photoshop.
What would the picture(s) be of and what effect are you trying to achieve?
 
Aren't we talking about HDR here? A number of identical shots with slightly different exposures, automatically combined in the camera?
 
Most multiple exposure shots you will see on the web, the sort where there are multiple images of the same person in the shot, will have been done in software and not in camera, as there are very few cameras that offer this facility.

If you are talking HDR, where multiple shots at differing exposures are blended to take the correctly exposed bits of the scene from each exposure, then again these will be merged in software.
 
Ok guys, I guess the way I'm going to achieve this is through software. Because buying a d700 or HDR isn't available to me as I haven't worn the lottery recently and am currently unemployed having only just graduated. Maybe in the future. Thanks for the info people!
 
The 450d does HDR :) I know cos mine does, its not a property of the camera, well a little but more so of the processing, all you need to do is take 3 or more bracketed shots and then play about with them in post processing, your manual will tell you how do take bracketed shots, you will need tripod/stand/beanbag etc and a non moving object, basically you press the shutter once, the camera takes 3 pics, a slightly underexposed, a normal and slightly overexposed one, then with software you combine the 3 to make a shot where the dark areas are not so dark and the bright areas are not too bright and bingo, HDR
 
HDR and multiple exposures are different things, let's not get confused here.

For digital multiple exposures take two (or more) separate photos and layer one over the other in software of your choice. Play with the layer blending mode and other settings until you're happy with it.
GIMP can do this and it's completely free.
 
Pentax K20s can do multiple exposure.

I think it's important to establish what type of image the OP want to create

If you want to describe the image you want to create or better yet post an example/link to an example and I'm sure either one of us or another member will be able to guide you on achieving the image
