Jasper Engineering: Photo Tools


A Slide Bar enables you to take a pair of photos for stereo viewing, of still life scenes, with a single camera. If you are new to 3D-Photography, I recommend the well written and easy to understand book "Photographing in 3D" by David Burder FRPS & Pat Whitehouse FRPS. It explains all the basic 3D photo procedures and is beautifully illustrated with lots of colorful 3D photos. It is listed in the "Reel 3-D" catalog.

The Slide Bar is attached mounted on a tripod. The Roller Block is attached to your camera, then slipped onto the Bar. A pair of photos is taken, one on the left of center, one on the right. After processing, the slides are viewed using any of the hand-held viewers or projector set-ups that will take regular 2"x2" slides or hand mounted full-frame slides.

We offer Slide bars in two convenient lengths: 8" (20.32 cm) and 16" (40.64 cm). A special Single Vertical Mount is available to mount cameras vertically instead of horizontally.

Slide Bars for Medium Format, Large SLR's and Heavy Duty Work are Now available in the following lengths: 18" - 28" with Twin Roller Blocks, Bubble Levels and End Safety Stops.
