<p><b>Anaglyph 3D</b> is the <a href="/wiki/Stereoscopy" title="Stereoscopy">stereoscopic</a> 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically <a href="/wiki/Red" title="Red">red</a> and <a href="/wiki/Cyan" title="Cyan">cyan</a>. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated <a href="/wiki/Stereoscopy" title="Stereoscopy">stereoscopic image</a>. The <a href="/wiki/Visual_cortex" title="Visual cortex">visual cortex</a> of the brain fuses this into the perception of a three-dimensional scene or composition.
</p><p>Anaglyph images have seen a recent resurgence due to the presentation of images and video on the <a href="/wiki/World_Wide_Web" title="World Wide Web">Web</a>, <a href="/wiki/Blu-ray_Disc" class="mw-redirect" title="Blu-ray Disc">Blu-ray Discs</a>, CDs, and even in print. Low cost paper frames or plastic-framed <a href="/wiki/Glasses" title="Glasses">glasses</a> hold accurate color filters that typically, after 2002, make use of all 3 primary colors. The current norm is red and cyan, with red being used for the left channel. The cheaper filter material used in the monochromatic past dictated red and blue for convenience and cost. There is a material improvement of full color images with the cyan filter, especially for accurate skin tones.
</p><p>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 <a href="/wiki/NASA" title="NASA">NASA</a> include <a href="/wiki/Mars_rover" title="Mars rover">Mars rover</a> imaging, and the solar investigation, called <a href="/wiki/STEREO" title="STEREO">STEREO</a>, which uses two orbital vehicles to obtain the 3D images of the sun. Other applications include geological illustrations by the <a href="/wiki/United_States_Geological_Survey" title="United States Geological Survey">United States Geological Survey</a>, and various online museum objects. A recent application is for stereo imaging of the heart using 3D ultra-sound with plastic red/cyan glasses.
</p><p>Anaglyph images are much easier to view than either parallel (diverging) or crossed-view pairs <a href="/wiki/Stereoscopy" title="Stereoscopy">stereograms</a>. However, these side-by-side types offer bright and accurate color rendering, not easily achieved with anaglyphs. Also, extended use of the "color-coded" "anaglyph glasses" can cause discomfort, and the <a href="/wiki/Afterimage" title="Afterimage">afterimage</a> caused by the colors of the glasses may temporarily affect the viewer's visual perception of real life objects. Recently, cross-view prismatic glasses with adjustable masking have appeared, that offer a wider image on the new HD video and computer monitors.

<p>The oldest known description of anaglyph images was written in August 1853 by W. Rollmann in <a href="/wiki/Stargard" title="Stargard">Stargard</a> about his "Farbenstereoscope" (color stereoscope). He had the best results viewing a yellow/blue drawing with red/blue glasses. Rollmann found that with a red/blue drawing the red lines were not as distinct as yellow lines through the blue glass.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1">[1]</a></sup>
</p><p>In 1858, in France, <a href="/w/index.php?title=Joseph_D%27Almeida&action=edit&redlink=1" class="new" title="Joseph D'Almeida (page does not exist)">Joseph D'Almeida</a><sup class="noprint" style="font-style: normal;"> [<a href="https://fr.wikipedia.org/wiki/Joseph-Charles_d%27Almeida" class="extiw" title="fr:Joseph-Charles d'Almeida">fr</a>]</sup> delivered a report to l'Académie des sciences describing how to project three-dimensional magic lantern slide shows using red and green filters to an audience wearing red and green goggles.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2">[2]</a></sup> Subsequently, he was chronicled as being responsible for the first realisation of 3D images using anaglyphs.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3">[3]</a></sup>
</p><p><a href="/wiki/Louis_Ducos_du_Hauron" class="mw-redirect" title="Louis Ducos du Hauron">Louis Ducos du Hauron</a> produced the first printed anaglyphs in 1891.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4">[4]</a></sup> This process consisted of printing the two negatives which form a stereoscopic photograph on to the same paper, one in blue (or green), one in red. The viewer would then use colored glasses with red (for the left eye) and blue or green (right eye). The left eye would see the blue image which would appear black, whilst it would not see the red; similarly the right eye would see the red image, this registering as black. Thus a three dimensional image would result.
</p><p>William Friese-Green created the first three-dimensional anaglyphic motion pictures in 1889, which had public exhibition in 1893.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5">[5]</a></sup> 3-D films enjoyed something of a boom in the 1920s. <sup id="cite_ref-6" class="reference"><a href="#cite_note-6">[6]</a></sup> As late as 1954, films such as <i><a href="/wiki/Creature_from_the_Black_Lagoon" title="Creature from the Black Lagoon">Creature from the Black Lagoon</a></i> remained very successful. Originally shot and exhibited using the Polaroid system, <i>Creature from the Black Lagoon</i> was successfully reissued much later in an anaglyph format so it could be shown in cinemas without the need for special equipment. Although not anaglyphic, <i><a href="/wiki/Jaws_3" class="mw-redirect" title="Jaws 3">Jaws 3-D</a></i> was a box-office success in 1983. At present the excellent quality of computer displays and user-friendly stereo-editing programs offer new and exciting possibilities for experimenting with anaglyph stereo.
</p><p>The term "3-D" was coined in the 1950s.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

<p>A stereo pair is a pair of images from slightly different perspectives at the same time. Objects closer to the camera(s) have greater differences in appearance and position within the image frames than objects further from the camera.
</p><p>Historically cameras captured two color filtered images from the perspective of the left and right eyes which were projected or printed together as a single image, one side through a <a href="/wiki/Red" title="Red">red</a> filter and the other side through a contrasting color such as <a href="/wiki/Blue" title="Blue">blue</a> or <a href="/wiki/Green" title="Green">green</a> or mixed <a href="/wiki/Cyan" title="Cyan">cyan</a>. As outlined below, one may now, typically, use an <a href="/wiki/Digital_image_processing" title="Digital image processing">image processing computer program</a> to simulate the effect of using color filters, using as a source image a pair of either color or monochrome images. This is called mosaicking or <a href="/wiki/Image_stitching" title="Image stitching">image stitching</a>.
</p><p>In the 1970s filmmaker Stephen Gibson filmed direct anaglyph <a href="/wiki/Blaxploitation" title="Blaxploitation">blaxploitation</a> and <a href="/wiki/Adult_movies" class="mw-redirect" title="Adult movies">adult movies</a>. His "Deep Vision" system replaced the original camera lens with two color-filtered lenses focused on the same film frame.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7">[7]</a></sup> In the 1980s, Gibson patented his mechanism.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8">[8]</a></sup>
</p><p>Many computer graphics programs provide the basic tools (typically layering and adjustments to individual color channels to filter colors) required to prepare anaglyphs from stereo pairs. In simple practice, the left eye image is filtered to remove blue & green. The right eye image is filtered to remove red. The two images are usually positioned in the compositing phase in close overlay registration (of the main subject). Plugins for some of these programs as well as programs dedicated to anaglyph preparation are available which automate the process and require the user to choose only a few basic settings.

<p>There also exist methods for making anaglyphs using only one image, a process called <a href="/wiki/Stereo_conversion" class="mw-redirect" title="Stereo conversion">stereo conversion</a>. In one, individual elements of a picture are horizontally offset in one layer by differing amounts with elements offset further having greater apparent changes in depth (either forward or back depending on whether the offset is to the left or right). This produces images that tend to look like elements are flat standees arranged at various distances from the viewer similar to cartoon images in a <a href="/wiki/View-Master" title="View-Master">View-Master</a>.
</p><p>A more sophisticated method involves use of a <a href="/wiki/Depth_map" title="Depth map">depth map</a> (a false color image where color indicates distance, for example, a grayscale depth map could have lighter indicate an object closer to the viewer and darker indicate an object further away).<sup id="cite_ref-9" class="reference"><a href="#cite_note-9">[9]</a></sup> As for preparing anaglyphs from stereo pairs, stand-alone software and plug-ins for some graphics apps exist which automate production of anaglyphs (and stereograms) from a single image or from an image and its corresponding depth map.
</p><p>As well as fully automatic methods of calculating depth maps (which may be more or less successful), depth maps can be drawn entirely by hand. Also developed are methods of producing depth maps from sparse or less accurate depth maps.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10">[10]</a></sup> A sparse depth map is a depth map consisting of only a relatively few lines or areas which guides the production of the full depth map. Use of a sparse depth map can help overcome auto-generation limitations. For example, if a depth finding algorithm takes cues from image brightness an area of shadow in the foreground may be incorrectly assigned as background. This misassignment is overcome by assigning the shaded area a close value in the sparse depth map.

<p>Viewing anaglyphs through spectrally opposed glasses or gel filters enables each eye to see independent left and right images from within a single anaglyphic image. Red-cyan filters can be employed because our vision processing systems use red and cyan comparisons, as well as blue and yellow, to determine the color and contours of objects.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11">[11]</a></sup>
</p><p>In a red-cyan anaglyph, the eye viewing through the red filter sees red within the anaglyph as "white", and the cyan within the anaglyph as "black". The eye viewing through the cyan filter perceives the opposite.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12">[12]</a></sup>
</p><p>Actual black or white in the anaglyph display, being void of color, are perceived the same by each eye. The brain blends together the red and cyan channeled images as in regular viewing but only green and blue are perceived. Red is not perceived because red equates with white through red gel and is black through cyan gel. Green and blue, however, are perceived through cyan gel.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

<p>Complementary color anaglyphs employ one of a pair of complementary color filters for each eye. The most common color filters used are red and cyan. Employing <a href="/wiki/Tristimulus" class="mw-redirect" title="Tristimulus">tristimulus</a> theory, the eye is sensitive to three primary colors, red, green, and blue. The red filter admits only red, while the cyan filter blocks red, passing blue and green (the combination of blue and green is perceived as cyan). If a paper viewer containing red and cyan filters is folded so that light passes through both, the image will appear black. Another recently introduced form employs blue and yellow filters. (Yellow is the color perceived when both red and green light passes through the filter.)
</p><p>Anaglyph images have seen a recent resurgence because of the presentation of images on the Internet. Where traditionally, this has been a largely black & white format, recent digital camera and processing advances have brought very acceptable color images to the internet and DVD field. With the online availability of low cost paper glasses with improved red-cyan filters, and plastic framed glasses of increasing quality, the field of 3D imaging is growing quickly. Scientific images where depth perception is useful include, for instance, the presentation of complex multi-dimensional data sets and stereographic images of the surface of <a href="/wiki/Mars" title="Mars">Mars</a>. With the recent release of 3D DVDs, they are more commonly being used for entertainment. Anaglyph images are much easier to view than either parallel sighting or crossed eye stereograms, although these types do offer more bright and accurate color rendering, most particularly in the red component, which is commonly muted or desaturated with even the best color anaglyphs. A compensating technique, commonly known as Anachrome, uses a slightly more transparent cyan filter in the patented glasses associated with the technique. Processing reconfigures the typical anaglyph image to have less parallax to obtain a more useful image when viewed without filters.

<p>Simple sheet or uncorrected molded glasses do not compensate for the 250 nanometer difference in the wavelengths of the red-cyan filters. With simple glasses the red filter image can be blurry when viewing a close computer screen or printed image since the retinal focus differs from the cyan filtered image, which dominates the eyes' focusing. Better quality molded plastic glasses employ a compensating differential diopter power to equalize the red filter focus shift relative to the cyan. The direct view focus on computer monitors has been recently improved by manufacturers providing secondary paired lenses, fitted and attached inside the red-cyan primary filters of some high-end anaglyph glasses. They are used where very high resolution is required, including science, stereo macros, and animation studio applications. They use carefully balanced cyan (blue-green) acrylic lenses, which pass a minute percentage of red to improve skin tone perception. Simple red/blue glasses work well with black and white, but the blue filter is unsuitable for human skin in color. U.S. Patent No. 6,561,646 was issued to the inventor in 2003. In the trade,
the label "www.anachrome" is used to label diopter corrected 3D glasses covered by this patent.

<p>(ACB) 'Anaglyphic Contrast Balance' is a patented anaglyphic production method by Studio 555.<sup id="cite_ref-NZ_Patent_505513,_AUS_Patent_785021,_UK_Patent_GB_2366114,_Canada_2352272_13-0" class="reference"><a href="#cite_note-NZ_Patent_505513,_AUS_Patent_785021,_UK_Patent_GB_2366114,_Canada_2352272-13">[13]</a></sup> Retinal Rivalry of color contrasts within the color channels of anaglyph images is addressed.
</p><p>Contrasts and details from the stereo pair are maintained and re-presented for view within the anaglyph image. The (ACB) method of balancing the color contrasts within the stereo pair enables a stable view of contrast details, thus eliminating retinal rivalry. The process is available for red/cyan color channels but may use any of the opposing color channel combinations. As with all stereoscopic anaglyphic systems, screen or print, the display color should be RGB accurate and the viewing gels should match the color channels to prevent double imaging. The basic (ACB) method adjusts red, green and blue, but adjusting all six color primaries is preferred.
</p><p>The effectiveness of the (ACB) process is proven with the inclusion of primary color charts within a stereo pair. A contrast-balanced view of the stereo pair and color charts is evident in the resulting (ACB) processed anaglyph image. The (ACB) process also enables black and white (monochromatic) anaglyphs with contrast balance.
</p><p>Where full color to each eye is enabled via alternating color channels and color-alternating viewing filters, (ACB) prevents shimmer from pure-colored objects within the modulating image. Vertical and diagonal parallax is enabled with concurrent use of a horizontally oriented lenticular or parallax barrier screen. This enables a Quadrascopic full color holographic effect from a monitor.

<p><a href="/wiki/ColorCode_3-D" title="ColorCode 3-D">ColorCode 3-D</a> was deployed in the 2000s and uses amber and blue filters. It is intended to provide the perception of nearly full color viewing (particularly within the <a href="/wiki/RG_color_space" class="mw-redirect" title="RG color space">RG color space</a>) with existing television and paint mediums. One eye (left, amber filter) receives the cross-spectrum color information and one eye (right, blue filter) sees a monochrome image designed to give the depth effect. The human brain ties both images together.
</p><p>Images viewed without filters will tend to exhibit light-blue and yellow horizontal fringing. The backwards compatible 2D viewing experience for viewers not wearing glasses is improved, generally being better than previous red and green anaglyph imaging systems, and further improved by the use of digital post-processing to minimize fringing. The displayed hues and intensity can be subtly adjusted to further improve the perceived 2D image, with problems only generally found in the case of extreme blue.
</p><p>The blue filter is centered around 450 nm and the amber filter lets in light at wavelengths at above 500 nm. Wide spectrum color is possible because the amber filter lets through light across most wavelengths in spectrum and even has a small leakage of the blue color spectrum. When presented the original left and right images are run through the ColorCode 3-D encoding process to generate one single ColorCode 3-D encoded image.

<p>A variation on the anaglyph technique from the early 2000s is called "Anachrome method". This approach is an attempt to provide images that look nearly normal, without glasses, for small images, either 2D or 3D, with most of the negative qualities being masked innately by the small display. Being "compatible" for small size posting in conventional websites or magazines. Usually a larger file can be selected that will fully present the 3D with the dramatic definition. The 3D (Z axis) depth effect is generally more subtle than simple anaglyph images, which are usually made from wider spaced stereo pairs. Anachrome images are shot with a typically narrower stereo base, (the distance between the camera lenses). Pains are taken to adjust for a better overlay fit of the two images, which are layered one on top of another. Only a few pixels of non-registration give the depth cues. The range of color perceived, is noticeably wider in Anachrome image, when viewed with the intended filters. This is due to the deliberate passage of a small (1 to 2%) of the red information through the cyan filter. Warmer tones can be boosted, because each eye sees some color reference to red. The brain responds in the mental blending process and usual perception. It is claimed to provide warmer and more complex perceived skin tones and vividness.

<p>This technique uses specific wavelengths of red, green, and blue for the right eye, and different wavelengths of red, green, and blue for the left eye. Eyeglasses which filter out the very specific wavelengths allow the wearer to see a full color 3D image. Special interference filters (dichromatic filters) in the glasses and in the projector form the main item of technology and have given the system this name. It is also known as spectral comb filtering or wavelength multiplex visualization. Sometimes this technique is described as a "super-anaglyph" because it is an advanced form of spectral-multiplexing which is at the heart of the conventional anaglyph technique. This technology eliminates the expensive silver screens required for polarized systems such as <a href="/wiki/RealD" title="RealD">RealD</a>, which is the most common 3D display system in theaters. It does, however, require much more expensive glasses than the polarized systems.
</p><p><a href="/wiki/Dolby_3D" title="Dolby 3D">Dolby 3D</a> uses this principle. The filters divide the visible color spectrum into six narrow bands – two in the red region, two in the green region, and two in the blue region (called R1, R2, G1, G2, B1 and B2 for purposes of this description). The R1, G1 and B1 bands are used for one eye image, and R2, G2, B2 for the other eye. The human eye is largely insensitive to such fine spectral differences so this technique is able to generate full-color 3D images with only slight color differences between the two eyes.<sup id="cite_ref-25" class="reference"><a href="#cite_note-25">[25]</a></sup>
</p><p>The Omega 3D/<a href="/wiki/Panavision_3D" class="mw-redirect" title="Panavision 3D">Panavision 3D</a> system also used this technology, though with a wider spectrum and more "teeth" to the "comb" (5 for each eye in the Omega/Panavision system). The use of more spectral bands per eye eliminates the need to color process the image, required by the Dolby system. Evenly dividing the visible spectrum between the eyes gives the viewer a more relaxed "feel" as the light energy and color balance is nearly 50-50. Like the Dolby system, the Omega system can be used with white or silver screens. But it can be used with either film or digital projectors, unlike the Dolby filters that are only used on a digital system with a color correcting processor provided by Dolby. The Omega/Panavision system also claims that their glasses are cheaper to manufacture than those used by Dolby.<sup id="cite_ref-26" class="reference"><a href="#cite_note-26">[26]</a></sup> In June 2012 the Omega 3D/Panavision 3D system was discontinued by DPVO Theatrical, who marketed it on behalf of Panavision, citing "challenging global economic and 3D market conditions".<sup id="cite_ref-27" class="reference"><a href="#cite_note-27">[27]</a></sup>
Although DPVO dissolved its business operations, Omega Optical continues promoting and selling 3D systems to non-theatrical markets. Omega Optical's 3D system contains projection filters and 3D glasses. In addition to the passive stereoscopic 3D system, Omega Optical has produced enhanced anaglyph 3D glasses. The Omega's red/cyan anaglyph glasses use complex metal oxide thin film coatings and high quality annealed glass optics.

<p>A pair of glasses, with filters of opposing colors, is worn to view an anaglyphic photo image. A red filter lens over the left eye allows graduations of red to cyan from within the anaglyph to be perceived as graduations of bright to dark. The cyan (blue/green) filter over the right eye conversely allows graduations of cyan to red from within the anaglyph to be perceived as graduations of bright to dark. Red and cyan color fringes in the anaglyph display represent the red and cyan color channels of the parallax-displaced left and right images. The viewing filters each cancel out opposing colored areas, including graduations of less pure opposing colored areas, to each reveal an image from within its color channel. Thus the filters enable each eye to see only its intended view from color channels within the single anaglyphic image. <a href="/wiki/RG_color_models" title="RG color models">Red-green</a> glasses are also usable, but may give the viewer a more strongly colored view, since red and green are not <a href="/wiki/Complementary_colors" title="Complementary colors">complementary colors</a>.

<p>Simple paper uncorrected gel glasses, cannot compensate for the 250 nanometer difference in the wavelengths of the red-cyan filters. With simple glasses, the red filtered image is somewhat blurry, when viewing a close computer screen or printed image. The red retinal focus differs from the image through the cyan filter, which dominates the eyes' focusing. Better-quality molded acrylic glasses frequently employ a compensating differential <a href="/wiki/Diopter" class="mw-redirect" title="Diopter">diopter</a> power (a <a href="/wiki/Eyeglass_prescription#Spherical_lenses_and_spherical_correction" title="Eyeglass prescription">spherical correction</a>) to balance the red filter focus shift relative to the cyan, which reduces the innate softness and diffraction of red filtered light. Low-power reading glasses worn along with the paper glasses also sharpen the image noticeably.
</p><p>The correction is only about 1/2 + diopter on the red lens. However, some people with corrective glasses are bothered by difference in lens diopters, as one image is a slightly larger magnification than the other. Though endorsed by many 3D websites, the diopter "fix" effect is still somewhat controversial. Some, especially the nearsighted, find it uncomfortable. There is about a 400% improvement in acuity with a molded diopter filter, and a noticeable improvement of contrast and blackness. The American <a href="/wiki/Amblyopia" title="Amblyopia">Amblyopia</a> Foundation uses this feature in their plastic glasses for school screening of children's vision, judging the greater clarity as a significant plus factor.

<p>Plastic glasses, developed in recent years, provide both the diopter "fix" noted above, and a change in the cyan filter. The formula provides intentional "leakage" of a minimal (2%) percentage of red light with the conventional range of the filter. This assigns two-eyed "redness cues" to objects and details, such as lip color and red clothing, that are fused in the brain. Care must be taken, however, to closely overlay the red areas into near-perfect registration, or "ghosting" can occur. Anachrome formula lenses work well with black and white, but can provide excellent results when the glasses are used with conforming "anachrome friendly" images. The <a href="/wiki/United_States_Geological_Survey" title="United States Geological Survey">US Geological Survey</a> has thousands of these "conforming" full-color images, which depict the geology and scenic features of the <a href="/wiki/National_Park_Service" title="National Park Service">U.S. National Park system</a>. By convention, anachrome images try to avoid excess separation of the cameras and <a href="/wiki/Parallax" title="Parallax">parallax</a>, thereby reducing the ghosting that the extra color bandwidth introduces to the images.

Note that the distant mountain images are aligned, placing them at the screen, and the confusing appearance in the lower right corner. <a href="/wiki/File:3d_glasses_red_cyan.svg" class="image"><img alt="3d glasses red cyan.svg" src="//upload.wikimedia.org/wikipedia/commons/thumb/a/a0/3d_glasses_red_cyan.svg/37px-3d_glasses_red_cyan.svg.png" decoding="async" width="37" height="10" class="noviewer" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/a0/3d_glasses_red_cyan.svg/56px-3d_glasses_red_cyan.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/a0/3d_glasses_red_cyan.svg/74px-3d_glasses_red_cyan.svg.png 2x" data-file-width="270" data-file-height="70" /></a> <small><a class="mw-selflink selflink">3D red cyan</a> glasses are recommended to view this image correctly.</small></div></div></div><div class="trow"><div class="tsingle" style="width:390px;max-width:390px"><div class="thumbimage" style="height:82px;overflow:hidden"><a href="/wiki/File:TwinPeaksDepthAdjusted.jpg" class="image"><img alt="" src="//upload.wikimedia.org/wikipedia/commons/thumb/7/73/TwinPeaksDepthAdjusted.jpg/388px-TwinPeaksDepthAdjusted.jpg" decoding="async" width="388" height="83" srcset="//upload.wikimedia.org/wikipedia/commons/7/73/TwinPeaksDepthAdjusted.jpg 1.5x" data-file-width="520" data-file-height="111" /></a></div><div class="thumbcaption">Image adjusted so that most objects appear to be beyond the frame.

<p>The adjustment suggested in this section is applicable to any type of stereogram but is particularly appropriate when anaglyphed images are to be viewed on a computer screen or on printed matter.
</p><p>Those portions of the left and right images that are coincident will appear to be at the surface of the screen. Depending upon the subject matter and the composition of the image it may be appropriate to make this align to something slightly behind the nearest point of the principal subject (as when imaging a portrait). This will cause the near points of the subject to "pop out" from the screen. For best effect, any portions of a figure to be imaged forward of the screen surface should not intercept the image boundary, as this can lead to a discomforting "amputated" appearance. It is of course possible to create a three-dimensional "pop out" frame surrounding the subject in order to avoid this condition.
</p><p>If the subject matter is a landscape, you may consider putting the frontmost object at or slightly behind the surface of the screen. This will cause the subject to be framed by the window boundary and recede into the distance. Once the adjustment is made, trim the picture to contain only the portions containing both left and right images. In the example shown above, the upper image appears (in a visually disruptive manner) to spill out from the screen, with the distant mountains appearing at the surface of the screen. In the lower modification of this image the red channel has been translated horizontally to bring the images of the nearest rocks into coincidence (and thus appearing at the surface of the screen) and the distant mountains now appear to recede into the image. This latter adjusted image appears more natural, appearing as a view through a window onto the landscape.

<p>Since the advent of the Internet, a variant technique has developed where the images are specially processed to minimize visible mis-registration of the two layers. This technique is known by various names, the most common, associated with diopter glasses, and warmer skin tones, is Anachrome. The technique allows most images to be used as large thumbnails, while the 3D information is encoded into the image with less parallax than conventional anaglyphs.

<p>Anaglyphic images made with cameras used to be constructed by having the lens covered with the appropriate coloured filter. Modern video/image rendering programs use a similar technique to achieve the anaglyph effect. Modern anaglyphic rendering programs used to use simulated filters over the virtual cameras, for Red/Cyan anaglyphs the left camera blocking all but red light being perceived and the right blocking all but the blue and green light being received. This worked okay for creating colourful anaglyph images but the results were prone to <a href="/wiki/Binocular_rivalry" title="Binocular rivalry">retinal rivalry</a>
</p><p>In 2001 Eric Dubois<sup id="cite_ref-28" class="reference"><a href="#cite_note-28">[28]</a></sup> released a paper titled 'A projection method to generate anaglyph stereo images'.<sup id="cite_ref-29" class="reference"><a href="#cite_note-29">[29]</a></sup> This paper described a method of filtering for anaglyph images that retained much of the colour and reduced ghosting and retinal rivalry The algorithm used to create this effect is called the least-squares algorithm. The result is a matrix that is applied over each virtual camera and forms a filter. His Matrix has been incorporated into many anaglyph programs such as StereoPhoto Maker<sup id="cite_ref-30" class="reference"><a href="#cite_note-30">[30]</a></sup> and threeJs's anaglyph effect.<sup id="cite_ref-31" class="reference"><a href="#cite_note-31">[31]</a></sup><sup id="cite_ref-32" class="reference"><a href="#cite_note-32">[32]</a></sup>

<p>Anaglyph images may use any combination of color channels. However, if a stereoscopic image is to be pursued, the colors should be diametrically opposed. Impurities of color channel display, or of the viewing filters, allow some of the image meant for the other channel to be seen. This results in stereoscopic double imaging, also called ghosting. Color channels may be left-right reversed. Red/cyan is most common. magenta/green and blue/yellow are also popular. Red/green and red/blue enable monochromatic images, especially red/green. Many anaglyph makers purposely integrate impure color channels and viewing filters to enable better color perception, but this results in a corresponding degree of double imaging. Color channel brightness % of white: red-30/cyan-70, magenta-41/green-59 or especially blue-11/yellow-89), the lighter display channel may be darkened or the brighter viewing filter may be darkened to allow both eyes a balanced view. However the <a href="/wiki/Pulfrich_effect" title="Pulfrich effect">Pulfrich effect</a> can be obtained from a light/dark filter arrangement. The color channels of an anaglyphic image require pure color display fidelity and corresponding viewing filter gels. The choice of ideal viewing filters is dictated by the color channels of the anaglyph to be viewed. Ghosting can be eliminated by ensuring a pure color display and viewing filters that match the display. <a href="/wiki/Binocular_rivalry" title="Binocular rivalry">Retinal rivalry</a> can be eliminated by the (ACB) 3-D <i>Anaglyphic Contrast Balance</i> method patented by<sup class="noprint Inline-Template" style="margin-left:0.1em; white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Please_clarify" title="Wikipedia:Please clarify"><span title="Patented by who?
