i recently tried to use the Exposure bracketing and multiple exposure feature in my D700. I have the following queries.
1.) What is the difference between Exposure bracketing and Multiple exposure feature. isn't it basically the same. I read somewhere that in Bracketing u get multiple pictures which you can blend later on using other software's, and in Multiple exposure we get one imagine file which is made from multiple exposures to the same file. however when i tried the multiple exposure feature, it recorded multiple images and i couldn't see the composite image obtained after blending of the multiple exposures.
2.) Also while using exposure bracketing, i could see the changes in exposure while i clicked pictures; however i couldn't see the same when i selected 7 frames in Multiple exposure. All the shots were taken at the same exposure.
3.) Lastly- even though i set the number of frames to 7, i still get 5 frames in a burst !

Make sure that you haven't got both Bracketing and Multi Exposure ON at the same time.
With Exposure Bracketing OFF:
In Multi Exposure Menu - Set the number of exposures to 9.
Set AUTO GAIN ON.
You MUST click OK for DONE each time you wish to take a Multi Exposure.
Set RELEASE MODE to Cl or Ch and press release ONCE and HOLD.
9 exposures will be taken and the end result is a single blended exposure.
NOW, put camera on tripod in an area where there is movement (people, cars etc) and take the nine exposure multi exposure shot in Single Shot mode, allowing a time to elapse between exposures and you will have (should have) a single exposure where none of the cars or people have registered because they only take up a ninth of the exposure time for the image.
Make sure that you don't kick the tripod during the process as you don't get the opportunity to align the 9 images in PS afterwards.
Yes. I believe I read that one use is to take multiple shots at fractional exposure settings (1/2 for 2 shots, 1/3 for three shots, etc). This is reported to yield improved color.
Now wouldn't it be great if Nikon would to give us a feature they provide on the D700's "little sister," the P7000 (aka "the traveling D700.)"
It allows you to take your multiple exposures and then it selects the best shot and saves only that single shot! It's called BSS (Best Shot Selector) and I use more often than any other exposure mode. Great for hand-held, static shots.
If I knew how to upload a photo I could send a single-shot/BSS comparison. (Yes, I checked the faq's but do not see any preferred resolution or scaling for uploads.)
Image uploads have to be less than 150KB -- anything larger will fail during upload. It is suggested to keep them 900 pixels or less wide, but I don't think there is anything specifically checking/limiting the dimensions.
Here is a sample of the BSS mode on the P7000 -- which is lacking on the D700. I shot this at 1/15 for emphasis. Neither of the images were processed in Photoshop except to combine them. They are viewed here at 100% magnification. Actually, I had a fairly stable shooting position and tried to get the best possible result, hand-held to keep the comparison fair.
Why do you suppose Nikon did not include BSS on the D700? Given the terrific noise handling capability of the beast, I am tempted to shoot more frequently in lo-lite situations, which suggests a more frequent use of slow shutter speeds where BSS really helps.
>Why do you suppose Nikon did not include BSS on the D700?
It may be that Nikon think the intended user base for the D700 want more control over shot selection. When shooting action in continuous mode, I know that composition, timing and other factors that the camera cannot detect (at least with today's technology... ) all help me to select which shot to use from a sequence.

Thanks for the comment, Brian!
However, as you know, the multiple exposure mode does not save a sequence of shots to mull over (as does the continuous mode) It melds all the frames from the sequence into a single shot which is saved while all the other frames are discarded. It does not save the individual frames.
I should have been more explicit in stating that my presumed application for BSS is restricted to handheld, lo-lite, static situations. There, BSS takes a continuous sequence, then decides (presumably on the basis of best detail or resolution) which is the best shot and saves only that shot, discarding the rest.
BSS tries to compensate for both handshake and target shake.
It's kinda like you took a continuous sequence, then selected the best shot yourself in postproduction. I don't argue with those who may prefer to do their own work.
I would think that BSS would be a terrific complement to the D700's awesome noisy handling capability which invites handheld, lo-lite, static shooting. For me, it would be high on the list deal makers.
Wouldn't it be boring if we all had the same preferences...
I can see the value of BSS for "snapshots" (and I don't mean that in any derogatory way), which is perhaps why Nikon offers it on Coolpix cameras. Even in the situation you describe, I wouldn't use BSS myself, preferring to see all the images and select the "best" one afterwards. I just don't like the idea of the camera choosing to throw away an image that I may have preferred.
But we're getting away from the point, which was Exposure Bracketing vis-a-vis the Multiple Exposure feature
Yes, I respect those who are loathe to allow the camera to make any decisions.
I do confess that I frequently use the D700 in its 'Coolpix' mode, however, as my main focus these days is family album shots wherein I'm more concerned about the emotion conveyed than in the technical perfection of the shot.
Again, I have complete respect and admiration for those who reach for the ultimate and I wallow in the posts on this forum!

Hi Charlie, Thanks for the reply ! i had infact had both barcketing and Multiple exposure on and so encountered the issue. I followed the instructions given by you and Multiple exposure thinge worked, the camera exposed the frame for 9 shots and i got to see a composite shot.... HOWEVER there is one issue, in the view finder the exposure doesn't change which means , the camera is taking 9 frames all at the same exposure, which defeats the purpose of the Multiple exposure feature. i understand in multiple exposure the camera will record 9 shots all at different exposure and the composite shot will be a blend of those different exposures there by giving an image which has lot more details from the highlights and shadows. This didn't happen when i clicked in multiple exposure mode and all the 9 frames were shot at the same exposure.
could you throw some light on this as to why it happened?

If you read the manual (p198) it gives a good description of what Multiple Exposure does.
If you take a 9 shot multi it simply takes each shot at one ninth of the indicated shutter speed and combines all into a single frame. I'm not sure if the shutter speed is assessed individually for each shot in a sequence and then divided by nine. This would be the most logical way to do it. The manual states that the indicated shutter speed of the blended image is the value of the FIRST shot taken. If the lighting does not change between shots then the shutter speed will not change albeit that the ACTUAL speed is one ninth of the indicated speed. I'm assuming the use of Aperture Priority here.
The best use of it (in my experience) is to cancel out moving objects (people, moving cars etc) during an exposure. I don't think that its intended use was anything other than that. It can be combined with the intervalometer to produce an automatically blended (up to) 10 shot multi. What you are suggesting is an in-camera HDR system?
You could experiment by manually changing the Exposure Compensation during a sequence to see if that does what you want. The overrall exposure would probably be correct but movement of the camera due to handling might be a problem producing a blurred image.
that was an interesting point u made about the use of Multiple Exposure. however what i read about the feature and from discussions on other forums, it in fact is and serves as a In-camera HDR function. Also going by the name, the feature wont be that useful if all the 9 frames are exposed equally as it doesnt add much to the image apart from the movement removal from the picture.
i am wondering what if the Exposure bracketing and Multiple exposure thing are on at the same time .... will the bracketing feature overrule the Multiple exposure?
Still need to figure out about multiple exposure feature to be used as an in camera HDR
Exposure bracketing simply takes a series of separate pictures with various EVs. Some people use this to make sure they nail the exposure, but I believe the most common use is to take a set of bracketed images that are combined in post-processing with HDR software. Depending on the bracketing settings, you end up with 2, 3, 5, 7 or 9 images with different exposure settings.
The in-camera multiple exposure is not for HDR. As others have said, the shutter is fired multiple times and the camera combines all the exposures into a single image. I did this in high school with a film camera by resetting the shutter but not advancing the film.
Multiple-exposure is for creative effects like these:
I've seen a different very creative and interesting use of multiple exposure. I believe it was done with in-camera multiple exposure and not by combining images in post-processing. The picture is of an airplane cockpit where the same person is sitting at the different stations in the cockpit. There was some real creative light control going on to make sure the cockpit was properly exposed and the multiple images of the person were solid and not ghostlike. I wish I could remember where I saw that picture.
There is another function called image overlay that allows you to combine any two images in the camera to be combined into a single image. The camera allows you to control the gain between the two images and it combines the two overlaid images into a single image. Here's an example where I took one sharply focused image of a flower and then a defocused image and combined them using image overlay:
I've seen other people use this to place the moon from one image into an empty sky in another image in the camera instead of combining images in post-processing.

There is no way of setting Exposure Bracketing if the Multi Exposure is turned on.
It (the bracketing) has to be done manually.
Having just tried a three exposure (-2; 0; +2) multi where the zero exposure had NO blown highlights I can definitely see a remarkable difference between a straight zero shot and the three frame multi.
Much more detail in the shadows!
However, I still have the reservations about the (possible) camera movement between shots induced by the handling of the camera when setting the manual bracketing.
It is definitely worth pursuing!
P.S. The result, in my case, was the equivalent of having A-DL (High) set on the camera.
