Our eyes are about 65mm apart, so they send slightly different images to our brains, which interpret the images and we see in 3 dimensions every day. In order to reproduce the 3d effect with photography, we need to obtain 2 images taken with a similar separation to that of our eyes; see My Cameras below.
Viewing 3D Images
The images on this web site are side-by-side 3D images, which can be viewed by a number of means, mainly depending on the width of the image.
Free-viewing 3D images is the simplest way for images up to 120mm wide; try to defocus your eyes, like when viewing Magic Eye images. If you see 3 images, concentrate on the center image and it will jump into 3D.
For images up to 175mm wide, I use the Loreo Lite viewer obtainable from https://www.widescreen-centre.co.uk/loreo-lite-fold-flat-3d-viewer-one.html, or the Lite Owl viewer designed by Brian May; https://shop.londonstereo.com/LITE.html.
For larger images I use prismatic spectacles, obtained from http://nvp3d.com/en/prism-glasses.
Some images are red/cyan anaglyphs, which may be familiar to most people from cinemas. Unfortunately, no anaglyph system yet made can reproduce colour properly; for example, pink orchids come out a pretty blue colour when viewed by red/cyan glasses. However, since anaglyph glasses are fairly common, I have included some images to be viewed by this technique.
My cameras
Most of the images on this website were taken with a Fuji W3 twin lens pocket 3D camera. It takes wonderful 3D images and has a glasses-free screen so I can compose the image in 3D as I take the shot. The camera has HD video capability. I have a Recsea WHF-3DW3 underwater housing for this camera, which enables all of the features to be accessed underwater.
I also use some single lens cameras, which are twinned and linked together via their USB ports, to make 3D rigs. I have a pair of Canon SX200IS cameras paired in this way, which have X12 zoom capability, and also a pair of more modern Samsung NX1000 cameras, linked similarly. The Canon pair are controlled by a free software download called StereoData Maker from http://sdm.camera/index.htm. Both rigs have video capability.
I use a Panasonic Lumix GX7 camera, fitted with the 3D lens attachment, for close-ups, particularly time lapse and for bird table photography.
My latest addition is a pair of GoPro 3+ Black cameras, complete with a coupling for 3D photography and an underwater housing. Synchronization of the shutters is excellent and I am very pleased with the results I obtained.
I use the free software StereoPhoto Maker obtained from https://stereo.jpn.org/index.html to align the stereo pairs of images and do some further processing.
