Artifact 01
Colour Anaglyph
COLOUR ANAGLYPH ARTIFACT 01
The purpose of this series of artifacts originates in my will to incorporate 3d parts in the film that I will present as my final project for this year. The reason that I elected to experiment with 3d techniques was not just the recent surge in 3d films in cinemas around the world, but also the amazing progress of the 3d technology over these last few years, culminating in the “Avatar” phenomenon.
The first artifact of this series was created using the first ever created 3d technique, the colour anaglyph method. Anaglyph images are used to provide a stereoscopic 3D effect, when viewed with 2 color glasses (each lens a chromatically opposite color, usually red and cyan). Images are made up of two color layers, superimposed, but offset with respect to each other to produce a depth effect. Usually the main subject is in the center, while the foreground and background are shifted laterally in opposite directions. The picture contains two differently filtered colored images, one for each eye. When viewed through the "color coded" "anaglyph glasses", they reveal an integrated stereoscopic image. The visual cortex of the brain fuses this into perception of a three dimensional scene or composition.
Anaglyph images have seen a recent resurgence due to the presentation of images and video on the internet, Blu-ray HD disks, CDs, and even in print. Low cost paper frames or plastic-framed glasses hold accurate color filters, which typically, after 2002 make use of all 3 primary colors. The current norm is red for one channel (usually the left) and a combination of both blue and green in the other filter. That equal combination is called cyan in technical circles, or blue-green.
The reason that I chose this particular scene from my film was that I wanted to see how the different 3d techniques would respond to a moving person (in the scene the actress is running at a high speed). At the end of this particular experiment, I believe that even the low-tech option of anaglyph images can provide a very satisfactory result as far as image and aesthetics are concerned.

Artifact 02
Grey Anaglyph
GREY ANAGLYPH ARTIFACT 02
The Three Dimensional Cinema (or the term 3-D for short) is used to describe any visual presentation system that attempts to maintain or recreate moving images of the third dimension, the illusion of depth as seen by the viewer. The technique usually involves filming two images simultaneously, with two cameras positioned side by side, generally facing each other and filming at a 90 degree angle via mirrors, in perfect synchronization and with identical technical characteristics. When viewed in such a way that each eye sees its photographed counterpart, the viewer's visual cortex will interpret the pair of images as a single three-dimensional image. Modern computer technology also allows for the production of 3D films without dual cameras.
During this particular experiment, I utilized the scene from artifact 01 (colour anaglyph artifact), using a grey anaglyph 3d technique instead. The reason behind the choice of the grey anaglyph is the fact that the film is shot in black and white, and thus a grey background will resonate more in terms of shade and depth.
Video games, theatrical films, and DVDs can be shown in the anaglyph 3D process. Practical images, for science or design, where depth perception is useful, include the presentation of full scale and microscopic stereographic images. Examples from NASA include Mars Rover imaging, and the solar investigation, called STEREO, which uses two orbital vehicles to obtain the 3D images of the sun. Other applications include geological illustrations by the USGS, and various online museum objects. A recent application is for stereo imaging of the heart using costly 3D ultra-sound with plastic red/cyan glasses.
Anaglyph images are much easier to view than either parallel (diverging) or crossed-view pairs stereograms. However, these side-by-side types offer bright and accurate color rendering, not easily achieved with anaglyphs. Recently, cross-view prismatic glasses with adjustable masking have appeared, that offer a wider image on the new HD video and computer monitors.
In conlusion the results that the grey anaglyph 3d technique produces are much more satisfactory, particularly in a black and white shot film.
