Multiple Exposures
The basic idea behind this approach is that the camera is set on a tripod and multiple shots are taken, each at a different exposure. A typical example would be where two shots are taken.

Multiple exposures can eliminate noise and also reveal more fine image details in the highlights and shadows. This will be most noticeable in the sharp specular highlights and pronounced textures.

Mix It Up with Multiple Exposures
With the E-P1's Multiple Exposure function available for still image capture you are free to tell a visual story your way, whether in a portrait, a landscape or a combination of both.
The combination of multiple exposures in Hand-held NightScene can result in ghosting caused by a moving subject while capturing the scene.
MULTIPLE EXPOSURES WITH ELECTRONIC FLASH Interesting multiple exposures can be made with only one or two electronic flash units. Multiple exposure pictures, besides being artistic and interesting, are often used to study subject motion and position.
There are several ways that you can create multiple exposures. Most cameras today offer multiple exposure capabilities.
In this mode the camera takes multiple exposures per second in a hope to capture that perfect moment. It is a good feature and it is helpful in most cases but not always.
Knowing that you can combine multiple exposures into a single image when working digitally, it becomes equally important to learn to see outside of the frame and beyond the proportions of the camera you're using.
Unlike multiple exposures with film you have complete control of how the blending occurs.
Helicon Focus is a Software product that lets you stack multiple exposures with different focal planes (or different areas that are in focus) to create a single image with increased DOF.
You can find it here.
As the term implies, multiple exposures involves exposing the same frame of film more than one time. Special effects shots can sometimes only be performed with the aid of multiple exposures.
It combines the dynamic range of multiple exposures into one image. Detail normally lost in shadows or washed out in overexposed areas are captured and revealed, better matching what we see with our own eyes. Well, that's the theory at least.
Because it reduces the number of steps needed to prepare to photograph, and it makes multiple exposures feasible. Multiple exposures aren't just for stunts, if you flash hasn't enough power, pop it off, twice, or even more times.
You can't bracket fast-moving subjects - a breaking news photo or sports action shot won't wait long enough for you to make multiple exposures.
Merging multiple exposures in Photoshop requires that nothing moves between when the constituent shots were made. If the wind is blowing and anything does move, it will register as a blur in the composite result.
Note that you can duplicate the effects of ND filters by making multiple exposures and combining them in software. However that means taking multiple images and if you have a moving subject that could lead to problems.
Technique: These stationary subjects also allow the framer photographer to approach and shoot multiple exposures. For those using a TTL automatic strobe with ISO 100 film, bracket down first to 50 ISO for a second shot, then up to 200 ISO for a third.
One makes longer exposures by making multiple exposures at 1/30. This is unique among rotating lens cameras; since you can make multiple exposures thanks to the electronic drive.
Next, it is ideal to use a tripod to shoot your multiple exposures because you don't want your hand to move the camera significantly between successive exposures, or there will be "ghosts" created in the final HDR image.
How to extend the dynamic range of digital cameras using multiple exposures. Results can even exceed the human eye.
Graduated Neutral Density (GND) Filters.
By simply referencing the index under Multiple Exposures, you’re directed to the pages to find the information. You read through that section and begin to think to yourself, “Now that wasn’t so bad! ...
The techniques they use to create surrealistic images combine multiple exposures to capture a wider range of value and color.
You can shoot multiple exposures a said above.
Or you shoot 1 pic with an overall good exposure and convert it later into 3 TIFF files.
In ACR or Appenture you set the single RAW file to +1 ev and save, set it to -1ev and save.
See how to use live view and picture controls; retouch images; use active d-lighting; create multiple exposures; use the interval timer; bracket exposure, flash, and white balance; use My Menu and the setup, custom settings and playback menus.

It requires shooting multiple exposures of the sky, often with a tracking mount on a tripod, and then combining the images for the final composition.
Special effects include slide sandwiches, multiple exposures, using wind to help create an "impressionist" look, and photographing through a textured surface.
Stroboscopic or Repeating Flash is a 'mode' available on some flashguns where under certain lighting conditions it can produce multiple exposures in a single frame.
Multi-Sensor Balanced Fill-Flash A type of automatic balanced fill-flash that provides flash output control while the camera's exposure control system determines the background exposure. Multiple Exposures A technique that involves taking or ...
It is easy to make multiple exposures with the Diana; the shutter on most Diana's can be fired as many times as wanted. Diana's have three aperture settings: sunny (f-16), cloudy (f-6.3), and dull (f-4.5).
Multiple exposure switch. Probably near the wind on lever, if you have one. Allows you to make multiple exposures on to one frame.
It is also useful for intermediate photographers who want to learn a few neat tricks for sharpening their skills. For example, it explains how to shoot multiple exposures, or how to set your camera's exposure when using neutral-density filters.
Unlike the green mode you can often adjust exposure compensation, AF, film winding and metering modes in addition to supporting AE lock, exposure bracketing and multiple exposures, depending on the model.
Shutter priority AE mode (Tv).
Continuous shutter - A feature found on more expensive digital cameras that enables you to take several images in quick succession; the images are saved to the memory card after the multiple exposures have been taken.
Double Exposure:
Two pictures taken on one frame of film, or two images merged in during post processing. Some cameras can have double exposure level depressed with multiple exposures and even with a motor drive
E ...
You could go the whole hog and take a toy film camera such as a Holga or a Lomo. Their cheap crappy lenses create a unique effect and you can also mess with multiple exposures by not winding the film on a full frame or even cross process your film ...
Along the way to reading this beautiful books, there is information concerning polarizing filters, double and multiple exposures.
