Wide-eyed Wonder: an artist's musings on three-dimensional vision

Some are color blind. I am stereo blind.

SIGHTINGS in 2012

Dr. Leonard Press, in his blog Vision Helps states that

“stereopsis is a quale of binocular vision that immeasurably enriches our daily lives.”

Throughout 2012, I recorded my own 3D qualia in scribbles in notebooks and texts to my iPhone and iPad, and on my homesteading album:

January 29
“I delight over the extruding branches of the two, snow covered honeysuckles in the evening light. I am so entranced I walk around each bush two times.”

February 5th
On my homesteading album, I wrote “I appreciate how I can use the balance board while doing dishes. It combines a core work-out with vision-therapy-enhanced ability to see 3D, as both sides of my brain are working at balance and therefore work more readily at bringing both eyes into play. Yes, I’m still leaving flatland. I never saw the hollow insides of soap bubbles before!

February 8th
Felt my eyes coming together on an apricot as I held it about 8″ from my nose. It was highly defined and inhabiting space. Later, as I rinsed a pan, the front edge appeared to be 3D.”

March 21st
In my homesteading album, I wrote “A very 3D bramble reaches out to me this morning.”

April 4th
I practiced physiological diplopia with the doorstop that is in the middle of the bathroom wall at Hennis, and “while looking at my fully extended finger, I continued to see two doorstops.

“Then, as I was washing my hands, I almost fell into the sink— it was so deep and the faucet so high!”

May 11th in my garden
“I bend to smell dames rocket. Then the onions pop!

September 2nd
“In the Hennis bathroom, I discover I can ‘hold’ the door bumper double image and track my finger with both eyes from 6” to arm’s length at intervals and see the distance between the double doorstop image widen and narrow. Then … I did it smoothly, like a trombone! No big stereo faucet pop after, probably because I was consciously looking for it.”

September 7th with one of our dogs
“Onslo’s nose becomes very long and 3D while we are relaxing on the couch.”

September 28th at Paint Oglebay
“After painting and lunch I tiredly hike up the hill feeling brain-drained and empty-headed, and thought ‘This is how I feel when I see 3D.’ Suddenly all the dead leaves popped out in sculpted beauty and the fronds of undergrowth along the path were moving independently and dancing in their individual spaces as I walked through, very very slowly, like a queen in fairy land.

December 30th
“While in the kitchen pouring, it feels like two eyes see. This is happening more often with space-intensive kitchen tasks.

Later, the folds of the shower curtain fill the space in front of me while I am seated as usual. This is the second or third time the curtain has taken on volume in the semi darkness of the light from an electric candle, just before bedtime.”

December 31st
“In the morning, as I approach the seating area around the wood burner, the angles of the furniture look strange and abnormal. Patrick seems further away and his feet appear larger … Foreshortened more.”

As an artist trained to draw the human figure, foreshortening of arms or legs is rather formulaic for me:closer is drawn bigger and farther away is rendered smaller than the way I see it. However, two or three times this last year, I actually SAW it. When viewed with two eyes, the approaching hand becomes much larger and the receding feet much much smaller.

It’s an apparent exaggeration of what I consider to be reality, from my normal, monocular point of view.

It could be that these sightings are merely “monocular depth perception cues.” I have described many monocular cues here, and even more cues and an excellent post on how they contribute to the “quale” of stereopsis can be discovered at Vision Helps with an awesome link to a computer rendition of kinetic depth cues added to a 2D image here:

However, the fact that these brief glimpses stop me in my tracks and cause me to grope for words to describe what I am seeing is evidence enough that something exceptional is going on, something beyond my normal monocular depth perception cues, something extraordinary, however esoteric it may be.

“… to experience a quale is to know one experiences a quale, and to know all there is to know about that quale.” —wiki
