1. Turn the rewind crank gently to take up any slack in the film.
2. Take your first photo. The 3800N has a special lens mask to help this process by blanking out one half or one quarter of the image, on other cameras a thin card mask over the lens achieves the same effect.
3. Hold the camera so that your thumb or finger is firmly on top of the rewind knob to stop it turning, whilst doing this press the rewind button on the base of the camera and then operate the film advance lever. By holding the rewind knob and pressing the rewind button, you allow the shutter to c0ck without advancing the film.
4. Turn the lens mask to cover the portion of the image which was just exposed.
5. Press the shutter using the same exposure value (EV) as previously used. Usually you'll use the same shutter speed and aperture, but by varying them and maintaining the same EV you can get some interesting effects.
6. If you're exposing more than two exposures on one frame then repeat as often as required.
7. Note that this is and always has been a bodge: the film frame often moves slightly between exposures except on a few specific SLRs which had a special multiple exposure setting. The V3800N is advertised as a multi exposure model but has no specific control for it, just the plastic lens mask.
