(non-commercial, using freeware) "Shade-Corrected, Parallel Pairs For Anaglyph" I also added this to my VirtualDub3D page: http://www.puppetkites.net/virtualdub3d.htm (Using a parallel pair as the source... AVI, MPEG 1 or numbered BMP) This method makes a parallel pair with the left image converted to grayscale and the right image left as a full color image, but with all the shade corrections, hue adjustments, etc, needed for a *perfect* anaglyph. This conversion has to be saved (you can use lossy compression, like MPEG 1 or DivX) and then opened in a 3D software viewer as a side-by-side (parallel) image and viewed as a "Color Anaglyph". Do not use a "half color" option, as that conversion has already been done. High resolution images are possible... basically as high as your computer can play smoothly. Of course upsampling (enlarging) is not recommended, as that degrades image quality. Basically, you use the same exact steps as in the field sequential anaglyph conversion, but you end the process by converting the anaglyph back to a parallel pair before rendering, and you delete the step that converts the image to anaglyph. The first 6 steps are basically identical to the "Red-Cyan, Shade-Corrected, Color Anaglyph - Field Sequential" method. 1) Add the "Hue/Saturation/Intensity" filter and desaturate only the colors that are possibly overwhelming in the images by 50%. (You can also adjust the "Hue" and "Intensity", and if needed, you can add multiple applications of this filter.) You can come back to this filter later, after you view the final anaglyph conversion, and change the settings. Even though this filter is applied first, you sometimes won't know what needs to be desaturated until you look at the final anaglyph conversion. 2) Add the "Deinterlace" filter and "Fold Side-By-Side Fields Together". 3) Add the "Interlaced RGB" filter. Under "Even Lines", put a check in the RGB2Y box. (Checking the RGB2Y box converts the left image to grayscale. Don't ignore this step!) 4) Open a second application of the "Interlaced RGB" filter. Under "Even Lines" and "Cancel", click on "G" and "B". Under "Odd Lines" and "Cancel", click on "R". 5) Add the "Resize" filter and change it to the size you want (half the height). Be sure to put a check in the "Interlaced" box in the resize filter. 6) Now, look at the finished anaglyph through the glasses. The red side usually needs to be brightened a bit, perhaps 5% or so. Do that with the "Color Equalizer" filter by increasing the amplification of the red or decreasing the amplification of the green and blue (equally). 7) Once you are happy with the anaglyph quality, go back and delete the "Interlaced RGB" filter in step #4. (Important! Leave the filter in step #3 alone! Do not delete that one!) 8) Go back to the Resize filter in step # 5, and change the size back to 100% (both width and height). 9) Add the "Deinterlace" filter and "Unfold Fields Side-By-Side". -- P.
