View Full Version : Double exposure?

Do any of the "G series" have an option of double exposure? I'm 99.9% sure they don't, but would be cool if they did.

No. I don't know of any digital camera that has that option. Its so easily done with software these days that its not even worth putting it in new cameras.

I've been messing around with a really long exposure at night and manually triggering a flash multiple times, I haven't nailed it yet, but it seems like it could work

How does one "manually trigger" the flash, (with remote) if possable. G2. And I'll prsute this new window of opertunity.

you press the button on it that says "ready/test" as you stumble around in the dark with the flash in your hand, your camera on a tripod and your shutter wide open for 15 seconds. : )
It's lame, and I haven't perfected it yet, but it sorta works. Next time I have time to mess around with it I'll post a sample. My last bunch of tests were lame and I chucked them to save disc space. Maybe I'll try it sober this time.

Far simplier to achieve with perfection using software like imagestacker.

Well, yeah, but what fun is that?
I could use photoshop to make a photo of Alan Arkin and Lindsey Lohan in wetsuits flying the millenium falcon over Cleveland (next Speed Challenge?), but it'd be much more exciting/interesting to get it in one shot, live.

Well then buy a a DSLR with double or multiple exposure features.
If you think post processing isnt part of digital photography, youve got a lot coming your way my friend.
In anycase, you do actually catch it live, because you have to be there firing multiple shots over extended periods of time, and then combine them either additively, averaging or whatever you choose to achieve your desired or intended look.
Fact is, G series cameras do not have double expose features built in, so find another way, and as my old school of engineering taught me, keep things simple.

You say "tomato," I say "where's your sense of adventure?" I said it was a weak idea, but it's fun to mess around with.
You're an engineer? I'd never have guessed!

To each their own,
Just a quicky though, you would be rather restricted with firing your flash more than twice consequetively (manually triggered or other method).Especially with long exposures, as the more flash you fire, the closer you get to overexposing. The way i see it, you would have to set up your shot for underexposure and look at bringing flash on relevant number of times to result in a correct exposure.. Extremely difficult to do without getting into numbers (flashguides, manually setting FEC etc).
Have fun,
Let me know if you perfect this, i wouldnt mind giving it a go.

When you press the test / fire button it is usually a full power shot that is not metered. This makes it almost unusable to start with without covering it up, bouncing, extremely guess work in my opinion

I have a shot of a guitarist where I was taking a slow sync shot, and two other P&Sers snapped shots. It froze the scene three time. Very wierd effect. Luckily I shot in raw, and was able to stop the exposure down. I had seen this type image created by others, but that was a first for me.

About Double Exposure on the G series: I was wondering the same thing a few weeks ago. Seems like it has to be done in software, although I took this picture by placing a piece of card in front of the lens (on a long exposure) and just moved the card away from the lens twice to capture some detail:

....it is not the greatest way to achieve the result, but can be interesting. I know some photographers use this technique when taking photos of fireworks in the sky at night to selectively capture just the nice BIG explosions, and not all the wee little pangs in between. They just set the focus up manually, and then move the card away from the lens when the BIG explosions appear. Something I have yet to try...

In theory, it sounds great.. and ive seen some great results of this method ) and in practise, it would work on any camera with 30 - bulb features... but on a G series, 15sec really limits your application.
