Grant Campos question re ImageTrack

Grant asks what an ImageTrack is and if he can just move the camera to
build up a lenticular image. Dealing with the second question first, the
answer is no, if you want any control over what you're doing. When
constructing a table top lenticular, there is a mathematical relationship
between camera movement, focal length of the lens, and the distance
between the three principal elements in the image and the camera (distance
from aperture point to foreground object, key object, and background). The
Imagetrack is a precision machined rail with a set of crosshairs that
target on a grid structure etched into the rail. In addition, it has a
set of calculation wheels for different distance ranges. Once all the
locations for the elements have been identified and calculated, you set
the ImageTrack on the correct grid range, and begin the exposure sequence.
Now, it *is* possible to build a multiple exposure camera so you can take
lenticular images of objects in motion. Burder is probably the expert on
this, but these cameras are beyond the price range, and the fabrication
skills of most people. Burder has build multi-lens cameras with many lens
configurations. If you have a pile of junk Nimslo cameras and want to
play, go for it, but be prepared for a serious investment in time and
experimentation.
If you're willing to live with tabletop (or you have a model who can
remain extremely still!) you can do pro quality work with the Imagetrack.
I've heard that NimsTec will process up to 9 image lenticulars before the
custom set-up pricing (which you need to negotiate in advance, I assume)
kick in.
Anyway, the $23 price for working in full frame 35mm and getting a single
8x10, or 10x8, using a 7 image lenticular negative is a real deal, IMHO.
