What's retinal rivalry?

Put simply in a 3D picture your brain is seeing 2 images but is attempting to overlay them into a single image, this however causes some problems with reds and blues.

Each eye is seeing a different picture which is masked by either a red or a blue lens, when the brain puts them into a single image it trying to merge 2 completely different colours into a single colour and it isn't really very good at it so what it causes is "retinal rivalry"

Put your 3D glasses on and look at this picture, the blues and oranges appear to flouresce.

However thanks to a guy by the name of Ernst Dubois this issue has been solved, he came up with a very clever algorythm which turns the offending colours into sort of muddy shades.

See the difference? but look again, your brain is being very colour and is making the colours look right even though if you view it without glasses  they look wrong, clever old brain eh?

How do you do this?, well once again SMM comes to help, when you go the anaglyph button, you will see several option "colour red cyan"  "half colour red cyan " "Dubois red cyan"

Just select the dubois option and the retinal rivalry vanishes
