Linear Set
No longer made or sold by Cokin
This is all I could find and know about these filters.
For use in manual cameras only. You expose the whole roll of film like a filmstrip through the narrow strip and then clip out the strange and deformed image you like.
Linear Set B 354 is a kit with both the B 351 and B 352
No longer made by Cokin, for use with manual SLR cameras
The linear shutter B 351 is for wide angel lens 20 -35 mm
.
1. Choose a wide angle lens, such as a 24 mm.
2. Place the lens cap over the lens, trigger and wind until the film is completely wound on the
camera terminal spool (as though you have finished your roll but have not re-wound).
3. Place your camera on a tripod, remove the lens cap, place the linear shutter in the filter
holder: Set your camera on B (lens open).
4. As the subject (in movement) passes through your field, rewind the film onto its spool (as though you were re-winding after having finished your roll). !
Hints: The re-winding speed should be as regular as possible, the ideal being to attach a slow
speed electric motor, so as to ensure a constant and regular re-winding speed. The relation
between the movement of the subject and the re-winding speed will determine the final result,
compressed, normal or elongated. With experience, you will be able to "follow" the subject and,
depending upon the irregularity of the movement, obtain unexpected and fascinating effects.
The exposition depends upon the re-winding speed, however as an indication, in bright sunlight,
set the camera at F8.
The linear shutter B 352 is for long lens 85 -200 mm
Important: Since the exposition is continuous along the length of film you rewind, do remember to tell your processing laboratory to leave the film in a strip, and not mount it as they normally would. It is for you to choose those parts of the film which interest you, to cut and mount them in 24 X 36 slide mounts. You can obtain "safe" and reasonable photographs by using the N02 slit-shutter, which will impart an impression of movement to a still subject, due to a blurring of the background. ~
Hints: Use a long lens, above 85 mm, as full aperture. The main subject must always be paced in the foreground., In fact the further away the background is, the greater the effect will become. The rotating filter holder allows you to orientate the effect as you wish.
