[photo-3d] Lenticulars, etc...

["John Billingham" <narjan@xxxxxxxxxxxx>]

 In a recent post, Dr. Monte Ramstad inquires whether anyone has 
produced "reasonable" lenticulars using consumer printers. I believe 
I have, although my personal preference for interlaced images like 
this is the "autostereoscopic barrier" image , which although much 
fussier with regard to viewing position, yields a much higher quality 
image given the same material size. I did begin my interlacing 
experiments assuming I was going to be making lenticulars, and I got 
acceptable results using 50 to 60 LPI material with images printed on 
an Epson 600  (720-1440 dpi) of course with paper-based media, 
differential expansion and contraction of the materials is a big 
problem, moreso as size increases and/or the pitch gets finer. 
The "barriers" I print with this printer, and I use a clear plastic 
inkjet transparency for the barrier "grid" and a plastic- 
based "backlight" material for the image. ( for display on a light 
box). Any of you who have attended a New York Stereoscopic Society 
meeting or a Tom Deering's Third Friday Stereo dinner may have seen 
some of these displayed.
