MULTIPLE EXPOSURESMIRROR LOCKUP
Intentional multiple exposures for creative effects can be made with the Nikon F2SB Photomic camera. To take a mUltiple exposure, perform the following: Make the in- itial exposure, depress and hold the rewind button on the camera's baseplate, and stroke the film-advance lever to cock the shu tter for the nex t exposure on the same frame; for each additional exposure on the frame, repeat the same procedure. At the completion of multiple ex- posure operation, stroke the film-advance lever once more to release the rewind button, cover the lens and make one blank exposure, and then resume normal operation. Note that during mUltiple exposure opera- tion, the camera's shutter speed can be changed to any setting for the desired shooting effect. Also, throughout the multiple exposure operation, the camera's frame counter will remain at the same setting as long as the rewind button is held depressed while stroking the film - advance lever.
The reflex mirror must be locked in the up position when using either the Fish eye-N ikkor 6mm f/5.6 or the OP Fisheye-Nikkor lOmm f/5.6 lenses, since their rear clements protrude into the camera body and interFere with mirror movement. Locking-up the mirror is a lso necessary when shooting with a motor drive unit at its top speed sett ing. To lock up the mirror, depress and hold the depth-oF-field button a nd turn the mirror lock- up lever downward until the white dot is aligned with the white index line. The mirror will remain in the up position until the lever is returned to the normal posi- tion.
