Digital Stereo Photographs
By accessing the links below you will find samples of my stereographic photographs; these can be printed or viewed on your computer screen to create remarkable 3D effects.
The basic principle behind stereo photography is quite simple: two "normal" photographs are taken that correspond to the view seen by the left and right eyes. To replicate the binocular view of the human eye, the photographs are taken about 2.5 inches (ca. 6.5 cm) apart. The individual photographs may be taken closer together (for macrophotography) or farther apart (to enhance the binocular effect of more distant subjects). To maximize effect the cameras are spaced apart 1/30 of the distance between the lens and the subject (thus for a subject only 30 inches (ca. 76.5 cm) from the camera lens, the spacing need only be 1 inch/2.6cm).
The individual photos can be taken with a single digital camera mounted on a "slidebar," or by a pair of digital cameras that are set on a bracket and triggered simultaneously (I use a Lanc Shepherd Pro controller
). One can still purchase used film stereo cameras, special "splitter" lenses, etc. All of the work presented here has been captured with digital cameras. For more on the process see John Hart's informative
How to view the paired images
The images accessible through the links below are paired parallel images. They can be viewed either as physical prints or on your computer screen. You will need either prisms
(good for traditional hard-copy prints) or a "pokescope
" (good for viewing stereopairs in any format) to view the images. Other methods of viewing that require additional hardware and/or projection equipment include shutterglasses or a dual-projector system. I hope to add some anaglyphs soon; these can be viewed with red/blue (red/cyan) glasses
New views are added on a regular basis!

Through the sample links on this page I offer images of Roman artifacts and sites that I have photographed or drawn myself over the past 25 years. These may be used freely and without charge for educational or scholarly purposes (please acknowledge the source). High-resolution images are also available, either by download (if available) or by emailing me (email@example.com). Images used for educational publications (journals, monographs, university presses, etc.) should be credited as: "copyright R. B. Ulrich"; if I've posted the image from a open domain source then the original source should be cited. Images of artifacts taken in museums should be reproduced by permission of the museum, which generally holds the rights to images of its collection. Those who wish to use my images for commercial purposes should inquire about fees.

Many of my parallel stereographic images are also located on Flickr. Samples can be accessed here, with instruction on how to view them.
