Re Lenticular animation

[P3D Peter Homer <P.J.Homer@xxxxxxxxxxxxxxxxx>]

Jim Ferguson enquired about doing lenticular animations . Some time ago I
tried some experiments myself in doing these to produce both 3D and moving
lenticulars (4D?). I filed down the edjes of the rectangular lens surround
of my first Nimslo and fitted "L" pieces over the top and bottom . This
enabled me to slide in various atatchments that I made . One of these was a
long strip with a single hole in it which was pushed across against an
elastic band . The cameras button was then pressed on a B setting (
obtained by reversing the batteries with a Japanese model) and held for a
moment while the strip was released followed by releasing the shutter. The
strip then was the shutter and exposed in sequence the film was sent for
normal 4 frame lenticular development . The two best examples were of a
waterfall which unortuneately of course seemed to run up hill if the print
was tilted the wrong way . And a shot of birds fluttering at a feeder where
it did not matter if the motion reversed. For a studio set up you could
just push the slider across each lens in turn and make exposures the normal
way of posed sequences of movement. The shutter cocking bar can be
disconected and brought through the bottom of the camera to allow it be
cocked without advancing the film. Some of the profesional lenticular
stereo cameras use a scanning arangment rather than multiple lenses so if
the subject moves during exposure that movement will be recorded as well.
Others just record movement but I have a comercialy produced example in my
collection called " Christmas Wink" A young woman dressed as father
christmas winks at the viewer as the card is turned and all in lenticular
3D.
