What do you mean when you say that the rewind crank need to be turn till very tied. how do i do that ? i am using a SLR dynax5 can i achieve that ? is it possible to explain in simpler term or more details cos i am really new thanks.
If there is no multiple exposure button on the dynax 5, then I don't think you can do it.
You will require a full manual camera to do it, i.e. You will require to do winding after every frame, and then manually rewind the film after the roll has finished. Not even with winding motor.
With reference to the FM2 body parts in mir site:
http://www.mir.com.my/rb/photography/hardwares/classics/nikonfmseries/fm2n/fm2manual/map.htm, you will see the Film Rewind Crank at the top left of the camera. Here is where you will rewind the film manually at the end of the film. To take a photo, you will need to wind the film and engage the shutter using the Film Advance Level. At the end of the roll, you will need to depress Film Rewind Button at the bottom of the camera. This button is to release the film takeup spool so that you can rewind the film back.
Therefore, in order to take multiple exposure, you will need to ensure that the film do not move. How do we achieve it?
1) Rewind the film until very tied, i.e. you are using Film Rewind Crank to wind back the loose film in the canister. Don't worry, the film will not move back as it is still engage in the film takeup spool.
2) After rewind the film to the maximum,
a) press the Film Rewind Button, which will release the film takeup spool, so turning the Film Advance Level will not move the film.
b) Turn the Film Advance Level, holding the Film Rewind Crank in same position (to ensure that the film does not follow), until the shutter is engaged.
3) Take your photo.
The multiple exposure button will take care of the above steps (except 3), and hence make our life easier.
A bit lengthy, but hope this explanation helps you in trying out multiple exposures on the same film.
