Multiple and double exposures: creating them

are they just talking about bracketing?

that will take multiple pictures of different exposures... It doesn't automatically merge the images for you though.

 

oh okay I think I found it, I just assumed those were single pictures.

here's an excerpt from olympus

MULTIPLE EXPOSURE

A Multiple Exposure function enables you to be creative right in the camera. Multiple images can be captured and combined to create one unique image. The creative possibilities are endless.

so basically it's just taking 2 pictures and overlaying them on top of each other. I originally though this thread was taking multiple pictures of the same thing and overlaying their pixels to get HDR or something.

 

I love doing multiple exposures, and it was one of the E-P2's selling points for me. If you're looking for the setting, it's on the second tab of the menu. Alas, you can't combine it with the art filters, but it's available under most of the other settings, I think. From the multiple exposure menu, you can set number of exposures (2 or not) auto gain, and overlay.

Auto gain I leave set to off. I think it adjusts the exposure value in anticipation of stacked exposures, and you'd probably want to use it if you were doing a shot where say only the subject's arms moved, and the rest of the scene was unchanged.

I find overlay useful and turn it on. It lets you see a "ghost" of your first exposure as you are composing your second. I'm used to doing doubles with film (where I often don't even remember what the first exposure was!) so this is a really nice enhancement.

When composing for multi-exposure, the most important thing to remember is that light, bright areas will dominate darker areas. I almost always want to do some adjustment in Photoshop on my doubles, too -- usually I just use "Curves" to improve the contrast, as doubles can be a little washed-out looking straight out of camera. Sometimes I play with color balance or saturation, too, but that's about the extent of my Photoshop skillz.
