DIGITAL PROJECTION
STUDIO 3D is attempting to set some standards for digital still projection (as an upgrade from the "old-fashioned" slide projection). Currently, "moderately" priced digital projectors run a native XGA (1024x768) resolution, so this is what we use for our image pairs (2xga). We recommend scanning images at 1500 pixel height, and scaling copies down appropriately.

NOTE: Some are moving to 2SXGA+ (dual 1400x1050). Same system, just more real estate!

Setup can also be used for stereo video

NEW!

The DEPTHQ® stereo video projector can project on to ANY surface (not restricted to silver or special rear screen) and can be run from almost any PC or laptop (with nVidia card). Hi-quality, wireless EYE3D shutter glasses are used with a long range IR emitter. 120hz for flicker-free performance! Studio 3D has projection systems for SALE.

Works with stills and video.

Some other DLP projectors will work, but most have a maximum refresh rate of 85hz.

2XGA LAPTOP PROJECTION

The DualHead2Go is the easiest way to run stereo slides from a laptop (check compatibility). Instant HORIZONTAL SPAN for your dual projectors, which allows for POWERPOINT or other slide show programs such as PROSHOW to run.

You can also use the Tritton Technologies SEE2 USB 2.0 adapter that allows a second video out for POWERPOINT shows... with the Tritton you'll need an "add-in" called POWERSHOW, which supports multiple monitors for stereo display. The VTbook pc card for Macs and pcs may be worth looking into, we've not tried it.

Laptops can also be used without 2nd monitor out by utilizing the DEPTHQ® stereo video projector.

2XGA COMPUTER PROJECTION

Projection of 2xga images from a (Windows) desktop or portable computer requires a dual head video card with a "HORIZONTAL SPAN" mode. The spanned monitors are set to 2xga (2048 x768) any slide show program should span the dual image exactly evenly.

We use PROSHOW with these attributes: Set SHOW OPTIONS/Custom Aspect Ratio to 2048x768. Also set CREATE EXECUTABLE/OUTPUT OPTIONS: Default window size to 2048x768 and START EXECUTABLE MAXIMIZED. Check "NO MENU" in MENUS option. In Gold uncheck "Include Intro Show" in SHOWS.

We also use POWERPOINT in speaker mode with Tritton adapter.

NOTE about MOVING your STILL IMAGES:
Using the techniques above will allow excellent stereo projection of NON MOVING still images (no pans or zooms). In order to do "Ken Burns style" panning and zooming, 2 separate video files must be created from 2 separate pictures files. We use Adobe Premiere, while some have used PROSHOW and outputting two separate video files. Projecting stereo video (especially HD) requires serious hard drives and CPU power! (Or dual DVD players with proper synchronizer.) Not for laptops... yet!

DIGITAL IMAGE ALIGNMENT
 using Photoshop

NOTE: Another EASY method for alignment (and many other stereo still processes) is to utilize STEREO PHOTO MAKER.
It's a wonderful FREE utility from Masuji SUTO of Japan.

2XGA images for digital projection

We call this format 2xga- it's basically 2 xga images attached as one... the images are crossed, with the left on the right side and the right on the left. This conforms to the .jps format set up by VREX, a leading stereoscopic company in NY, which is compatible with their Depthcharge interenet browser software (and other companies, like Canopus, are supporting this format as well). An advantage of the crossview is that any size image can be freeviewed. The Pokescope software will recognize this format with either the .jps or .jpg extension. (Note: though the images are crossed in the original file, most stereo software can show the pair as parallel or crossed- or anaglyph or interlaced for that matter!)
If an image does not fit the xga aspect ratio, the image pair should be set up with the same height (768 pixels) with black added to the sides to fill out the image to 1024 pixels per side.

STEREO SLIDE (transparency) PROJECTION 
In ancient times, people projected still images using 35mm transparencies called SLIDES (or "chromes"). The slide mounts were 2"x2" square, and the size of the image was 24mm high by up to 36mm wide. For stereo, images were often cropped to 32mm wide (making an image that was "TV" size, with a 3:4 aspect ratio). Two projectors for one stereo image, four projectors allows one stereo pair to dissolve to the other, and back again.

Stereo slide projection has most professionally been done using multiple 2x2 (35mm) projectors. STUDIO 3D has created a number of stereoscopic slide presentations for schools, museums and clubs. Equipment has included:

  • 4 Ektagraphic slide projectors with HotSpot bright lamp housings, on Chief stands
  • 4, 70-120mm or 4, 110-200mm zoom lenses with polarizers
  • Dataton dissolve unit and Trax digital program (via Mac computer)
  • Various size silver screens, from 5x7.5 to 10x14.5

All stereo pairs are set-up for cross-viewing.

STUDIO 3D stereo slide presentations include:

THE THIRD DIMENSION
an hour-long stereo slide production created especially for the college market, as an overview of the history of dimensional imaging. The show is in four parts:

ANTIQUE 1850-1938 / VIEWMASTER 1939- present / 3D BOOM 1950's / MODERN STEREO Contemporary

THE EYES HAVE IT
a 10 minute stereo slide production produced for The Liberty Science Center in Jersey City, NJ. After several successful years, another copy was generated for the Imaginarium in Ft. Myers, FL (still running!) and The Pacific Science Center in Seattle, WA

POWER OF PEOPLE
special 10 minute presentation for the National Association of Campus Activities

THE 3D SHOW
a 45 minute program designed by Aubrey Productions, Ltd., and toured to grammar schools by Ron Labbe from 1992-1996
