Multiple exposure lets you combine two or more exposures into one image without using any post processing software like Photoshop. This option is only available in P, S, A and M mode. Sometimes it’s fun to do an experiment with your camera settings and if you are planning for fun shooting, trying multiple exposure is one good option. Nikon offers a feature called "Multiple Exposure" which combines two or more images inside the camera using the RAW data from the sensor, producing images that are blended together smoothly. If you are interested to try this feature on your camera, let’s go and see how to setup the camera to blend multiple exposure shots in a single frame.
Camera settings for Multiple Exposure
1. Go to the Shooting menu by pressing the Menu button on the back of your camera.
2. Choose Multiple Exposure from the Shooting menu.
3. Select the Number of shots you want to combine into a single frame. Nikon D90 allows you to select up to 3 shots.
4. Choose Auto Gain and select either ON or OFF. When ON is selected, Nikon D90 will divide the total exposure of the image by number of shots specified above. For example if you specified number of shots 2 and Gain is ON, each shot will get ½ of the total exposure. If Gain is OFF, total exposure is applied to an individual shot.
5. Press OK to set the Gain.
6. After you are done with these settings, scroll up to the Done and hit OK. Upon completion, you will see the Multiple Exposure icon (overlapping rectangle) on the LCD screen.
7. Now you are ready for the shot. When you take the first shot, Multiple Exposure icon on the LCD screen starts blinking until you finished shooting all the series (no of shots you specified). If you are in a continuous shooting mode, all the series will be shot in single burst shot. When you have taken all the series, blinking icon disappears and camera will turn off Multiple Exposure feature automatically.
Here are the couple of shots I took today to try out the Multiple Exposure. I set the number of shots 2 and shot couple of pictures with the Gain OFF and again I took another couple pictures with the Gain ON. I took all the series of the pictures with the exact same exposure settings. I didn’t use a tripod for these shots and that is why you can see little overlapping between the two frames when combined to a single shot. When you take two shots, camera will process itself and combine them into a single shot giving you the Multiple Exposure effects in a single image. I have seen people creating ghost effects using this technique which looks pretty cool.

I used only one teddy bear to get this shot. What I did is, first I put the teddy bear on the left side and took a shot. Then, I put the same teddy bear on the right side and adjust a frame so that both can fit into a single frame after camera combines two images into one and took the second shot. After camera combined both shots, this is what I got as a result. It's not a perfect shot as I didn't use a tripod and didn't align the pictures properly but you can get an amazing effects using this technique if applied properly. Nice thing about this feature is that you don't have to use any software to get the effect, your camera will do it for you automatically.
