| In one of the pics on here I see a double exposure. Could someone in here tell me how you do this with a digital? |

basically you either mix two photos together in photoshop, or you have to blackout the camera in mid exposure and unblack it after you get the new setup completed.

Some digital cameras have the ability to combine two exposures into a single file completely internally.
It can also be done with a long exposure and either covering/uncovering the lens with a black card, or shooting in a darkened environment and firing off multiple flashes.
If you are in doubt about whether a photo was accomplished within the rules, you can request validation, but PLEASE vote assuming every photo is completely legal -- if it's not, we'll DQ it, but if it is legal, you should give it the vote it deserves. |

I believe some from the Nikon Coolpix series have this ability. |

A clip from this article:
Nikon Image Overlay - D2X
Image Overlay – Multiple Exposure
The D2X has the ability of doing multiple exposures and in fact, the D2X gives you two methods for doing double/multiple exposure. Image Overlay is a double exposure feature. Multiple Exposure permits you to take 2 – 10 exposures and combine them into 1. This is all being done in camera, Nikon Capture or some other program is not required to make this happen.
This is a semi complicated feature. You have the ability to change the gain between frames during the processing with Image Overlay or during the capture with Multiple Exposure. The resulting single image from this process is saved to the CF card as a new image.
Why might you want to use these new features when you have Photoshop? Being able to combine two photographs on the fly where 1 is over exposed for shadows and 1 is under exposed for highlights, you can see instantly while still shooting if it will work or not. There is of course the obvious, taking a photo of the moon and then doing a multiple exposure placing it where you want in the next shot. It's a pretty cool feature that has lots of creative potential.

Some of the Fujis, too. The 602 that I used to have had this feature. Used it quite a few times for some online challenges.

Yup, the Fujifilm 602 does it:
Heres one I made earlier...

| I would like to play with multiple exposures within the camera. This fits within the basic editing rules? |

There is a limit isn't there in how much a digital camera can take in terms of the sensors abaility to stay open and receiving data.
Didn't I read that after about 6 secs, you start to get major failures in the blue channel?

Longer exposures will begin to develop more noise, which can be minimized by lowering the temperature (astronomic cameras have cooling systems).
Many cameras in use by members here support exposures of 30 seconds or Bulb Mode (unlimited. manual shutter). |

Not necessarily. It really depends on the sensor and associated electronics. I've used exposures measured in minutes, in fact take a look at my most recent failure challenge entry, that's a single 8-minute exposure.

| If your camera does not support a duble exposure it is possible to do the trick with a long exposure, set up your shot open shutter, have someone move in frame then close shutter, or vice versa. Another way is to get a flash that does a strobe or a strobe light and have somthing move across the frame,the flash of light will make the movement freeze and depending on the rest of the lighting make spaces between movement look like streaks, did this a few times with my 4mth old in his swing, made one baby look like 4 :) Do this in a dark or dim room and you wont get as much motion streaking and can look like a multi exposure shot. |
