There is one other point of interest, which concerns the overlaying of a blurred difference image onto the original left image. This relates to the accepted maximum differential range of 3D depth discussed on pages 2 & 3 of 'Naked Eye 3D perception from conventional 2D displays.pdf'. This is that, if the range of depth is excessive, together with a plain local background and very high edge contrast, there will be a substantial ghosting visible. However, in the case of a similar extreme depth range in the presence of a high local structural scene content, there is rarely any observable ghosting at all. On the other hand the combination of very high contrast, plain background and extreme depth range doesn't occur very often - and it is likely that, in such circumstances, perception is concentrating on the structured parts of the scene anyway! All the foregoing have been discussed in depth in the latest report on 3D viewing (‘Recent new studies concerning NE3D and other methods of viewing 3D.pdf’), together with illustrations of the effects when viewing with simple & structured scenes.
