AV News 179 - February 2010 The positioning tools allow you to adjust their relative positions to increase or decrease the 3D effect. When viewing through red/cyan anaglyph glasses, each eye will only see the filtered version as taken from the "left" and "right" viewpoints, allowing the brain to re-assemble the scene into 3D. 4. Open the image in Photoshop or similar and crop to your required size. Because the anaglyph is composed of two overlapping images, there will always be a need to tidy-up the result into the final version. 5. Assemble your sequence as normal - except that this time you also need to be wary of using two adjacent images that have a large shift of perceived depth, as this can cause the audience to go cross-eyed during the dissolve! The image quality is never going to be anything like as good as the original, as the colours will have been compromised during the anaglyph process. In particular anything that is naturally red or cyan will appear as a totally false colour. The result is more of a novelty than anything else, and if you do make a sequence keep it nice and short! Anaglyph glasses can be bought from various places (eBay is always a good source) and depending on quantity can be found for 30p - 50p each. They are often available as free giveaways from time to time, so its worth watching out for them.
