On 8th February, our 3D Extravaganza Training evening started with Graeme Mitchell setting out the history of 3D imaging stretching back to the mid-1800s. Apparently an  evening round the fire with the stereoscope was the late Victorians' equivalent of television.

That technique was based on taking pairs of images and viewing them side-by-side through a stereoscope. Methods developed over the years and the anaglyph method with two superimposed tinted images being viewed through tinted glasses is the current favourite. This involves taking two images from camera positions spaced horizontally equivalent to the space between human eyes.

Thanks to digital photography and some effective but inexpensive post-processing software this is now easy to do. Graeme showed us examples of his work and provided the glasses to view them. He also produced some impressive images both using a camera and using his mobile phone before our very eyes!

The anaglyph method lends itself to static subjects as you need to move the camera. After tea Victor Prystaj revealed his rig for producing the old-style stereo pairs.

Since the images are taken at the same time, the subject can be moving. He displayed some of his work and provided the stereo-viewer glasses to get the 3D effect. Victor's interest in 3D was originally sparked by an earlier talk by Graeme at BPS some years ago. I think a good few of tonight's audience will be having a go too!

First away is Tony Kilcoyne with the two anaglyphs shown above taken on the night. Now all you need are the glasses!
