being a tetrachromat means your eyes read color differently, especially reds...leading you to believe tetrachromats have a fondness for b&w infrared because of it.
I believe a lot of post processing allows an image to be viewed by others as a tetrachromat does, increasing intensity and ranges...
almost all tetrachromats are females, to varying degrees.
these images, one deepened saturation and warmth and the other converted to infrared, are a great example of the many shades of red in color shown through tonal range in black and white.
after quite a bit of research...in my little mind I believe there is a relationship of some kind between tetrachromats, the color indigo, the eye's cone shape....and a small island in the south pacific, guam...the island of the colorblind (by oliver sacks).
ps: I use picnik.com a lot for post processing.
here are some great links if you're interested - especially note this one from nikon:
