Just sent the Jesus image question to someone I know who works electro optics and detectors for digital imagery to see if he knows...Retaining information doesn't always equate with the ability to think, wisdom or understanding. I can look up most any information someone else has learned, on the internet but I can't replicate experience. I guess we all have some unique combination of knowledge and insight that others may not. Like my profession was based in optics and I'm not sure how that Jesus illusion works. Something probably to do with the rods and cones of the retina and latent light stimulation on the optic nerve, causing the high contrast negative image to reverse into a positive. I know you can figure which eye you have is dominant by poking a hole through a piece of paper, then line up an object at some distance (20 ft) with both eyes open looking thru the hole. Now with the hole still lined up on the object close each eye one at a time. Whatever eye still sees the object is your dominant eye and the one you used to see the object with first. Though we have two eyes, one eye transmits the image to the brain first, while the other lays a separate image over the first to give the brain depth of vision and binocular sight. The retina actually sees images upside down like a mirror in a camera but the brain turns them right side up. Boring for others fascinating too me,, lol.
I have wondered from time to time... but being out of the country for so long now? They could never find me. Not that I had a bunch of one-nighters, but a enough.One of my fears,, knock-knock-knock.. who's there? Hi daddy you never knew me.
