Shadow People

[Nugget]

 Historically, the idea of "demons"  caused so much suffering.

I think exalting one ethnic group of people above all others falls in the same catagory as demonic. It has certainly done the world a world of harm.

I was looking for information of the rods and cones and the parts of the light spectrum they "see". I was wondering if the rods can "see" into the ultraviolet and infra-red.

For example, the cones are colour-sensitive and according to the medical texts there are three types corresponding to red, green and blue. Orange light stimulates both red and green cones. That gives us the usual colour spectrum of red, orange, yellow, green, blue, indigo, and violet.

Whereas the consensus seems to be that the rods can only detect the amount of light hitting them. So, someone with only rods would see the world in black and white.

The question of do the rods "see" into the ultraviolet, is something I have no answer for. Perhaps someone who can answer the question might chime in?

That said, here is an interesting, for me at least, point to consider.

Ordinarily, our eyes are drawn to objects that are brighter than the background. For example, when we look at a tree in daylight, we habitually focus on the green leaves, and not the shadows between the leaves. We also focus on colour rather than the black and white in a landscape.

So we have to make an effort to train our vision to notice the shadows.

Now, most shadow people sightings are said to be seeing shadows out of the corner of the eye. That is the peripheral vision. So we need to take movement into account, as our peripheral vision is very sensitive to movement.

That said, I have one young lady who visits here who can see the shadow people by looking straight at them in daylight. The young lady doesn't like dark corridors and always sleeps with a bright night light. That suggests to me her eyes (rods) are more sensitive to movement than normal, or perhaps she simply never lost the ability to see the shadow folk from early childhood.

I should ask her if she is colour-blind. When she draws the shadow folk, she always draws them in black and white.

Which, I guess, brings us to the subject of dicyanin glasses . . .

Good stuff, thanks for the research.

I was hoping you'd look more into the ability of rods to see near-infrared light. Here are the quotes from the ATS thread.

"Here is some other information that claims flashes of light may allow humans to "see" infrared light.

'In some special conditions, the human eye can indeed detect infrared light according to scientists at Washington University School of Medicine in St. Louis. “We experimented with laser pulses of different durations that delivered the same total number of photons, and we found that the shorter the pulse, the more likely it was a person could see it,” Vinberg explained. “Although the length of time between pulses was so short that it couldn’t be noticed by the naked eye, the existence of those pulses was very important in allowing people to see this invisible light.” '

'“The visible spectrum includes waves of light that are 400-720 nanometers long,” explained Kefalov, an associate professor of ophthalmology and visual sciences. “But if a pigment molecule in the retina is hit in rapid succession by a pair of photons that are 1,000 nanometers long, those light particles will deliver the same amount of energy as a single hit from a 500-nanometer photon, which is well within the visible spectrum. That’s how we are able to see it.” '

So near-infrared light (1000 nm) under these conditions appears to the eye to be cyan light (500 nm), which is what the rod cells are most sensitive to. Perhaps paranormal ghostly images may be emitting near-infrared light that is being seen by rod cells as cyan light. A couple of questions that come to mind are how rapid are these photon pulses and do the infrared photons need to be aligned in a laser beam to be seen? Both of these aspects could somehow be factored into how a near-infrared camera may be used to capture these images and prove that they are not just figments of the imagination. "

I think I confused myself reading too much sciencey stuff looking into it.

I've been meaning to reread The Human Atmosphere by Walter J. Kilner. That is the textbook on dicyanin and seeing outside the normal visual range. From memory, Kilner says something similar.

For everyone, here is a link to a good, legible copy of the book in PDF format: The Human Atmosphere - Walter J Kilner. It is also free without signup to anything.


A quote from the book (footnote, page one):

The author considers that ninety-five per cent. of people with normal eyesight can see the aura. One gentleman states that only one person out of four hundred, to whom he had tried to show the aura, was unable to distinguish the phenomenon.

It is a good thing We are still a young site here at MPP, the threads are not fast moving. Since I am spending most of my time on my house roof repairing for repainting, I haven't been able to sit back and do some research at this point in time.

Nevertheless, I don't like to leave this thread hanging. So here is a picture I took of what it is like to look through the dicyanin glasses.

Thanks for the contribution!

Interesting.

You've jogged my memory about experiments in the 1970s here in Australia. This was back in the days of black and white TV. What they did was to broadcast an image in black and white and asked viewers to telephone a number if they saw colour on the black and white TVs. I saw one of these, and it was in green, magenta and maybe a purplish colour and, A rocket space ship and stars I think it may have been according to my old memory. The image was rather quick and unexpected. Everyone made fun of me explaining: you can't possibly see colour on black and white TVs : (

So I went searching and found something similar:

The Squirt Soft Drink Subjective Color Acid Test

On July 25, 1967, television viewers with black-and-white TV sets were startled to see flashes of color on their monochrome screens for about ten seconds during a 60-second soda-pop commercial. A letter to a columnist in the September 14, 1967 Detroit Free Press asked, "Before I see an eye doctor, let me ask Action Line: Is it possible to pick up color TV on a black and white set? I SWEAR I saw a Squirt soft-drink commercial in color. Not pink elephants Green Squirt!" The image was described in the newspaper column as a red, green and blue sign that had flashed on the screen.

A viewer in Chicago told Popular Photography magazine (July 1968), "I saw pink! It knocked me for a loop...the letters S-Q-U-I-R-T looked greenish or light turquoise...and it kept up for maybe 10 seconds." (Meanwhile a viewer in San Francisco claimed he didn't see anything colorful.)

It was the national debut of an experimental television commercial using a special production process that would give the optical illusion of color. The commercial first aired a few months earlier locally on KNXT, the CBS-owned television station in Los Angeles, and viewers there were just as stunned. Squirt and its advertising partner Color-Tel Corporation of Los Angeles, at the time decided to make no prior announcement of this experimental commercial, preferring to see just how viewers would respond. And respond they did. Within hours, thousands of viewers were asking if they really saw what they thought they did, color on their black-and-white TV screens, according to Popular Electronics magazine (October 1968).

In the article, they reference another article:

The burst of color was not "living color" (as NBC frequently touted in the 1960s), but something called "subjective color." The process was developed by James F. Butterfield of Color-Tel, a corporation founded in Los Angeles in early 1966. It gave the illusion of color by pulsating white light in a particular sequence for each color with a rotating device attached to a regular black and white TV camera lens.

This goes back to an article in an old Popular Mechanics magazine from 1968, that talks about the nerve codes.

Slightly over 15 years ago, Butterfield
reasoned that, if the frequencies of the
nerve codes for specific colors could be
mathematically analyzed, it would be
possible to feed the cortex synthetic
color data.

This could be accomplished
by stimulating the cones with flickering
pulses of white light, keyed to match the
known nerve frequency for a given hue.

If the theory was correct, such flickering
white light would then appear to the
viewer to have color.

I'll tidy up the article and post it here.

This kind of research has been going on for quite some time.
