What is saturation in terms of wavelength?

Click For Summary

Discussion Overview

The discussion revolves around the concept of color saturation in relation to wavelengths and the potential for creating materials or devices that could enhance color saturation in visual perception. Participants explore theoretical ideas about lenses or glasses that could amplify color saturation without relying on electronic means.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests the possibility of a lens or glasses that could enhance color saturation by altering the texture or color of the lens.
  • Another participant proposes that a material would need to amplify light intensity while passing through it, but expresses skepticism about the feasibility of such a material.
  • There is a discussion about how increasing light intensity affects brightness but does not necessarily enhance saturation, as saturation involves the mixing of additional wavelengths.
  • A participant mentions the need to obtain separate RGB images to manipulate saturation through a process of subtracting luminance signals.
  • Some participants express a desire for "saturation glasses" that could improve visual experience in gloomy environments.
  • There is a debate about the definitions of electronic versus electric devices, with participants providing differing perspectives on the terminology.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility of saturation-enhancing devices, and there are differing opinions on the definitions of electronic and electric devices. The discussion remains unresolved regarding the practical implementation of the proposed ideas.

Contextual Notes

Some claims about the physiological effects of certain glasses are mentioned, but specifics are not provided. The discussion includes assumptions about the nature of light and color perception that are not fully explored.

could it be possible, to make a, for example, and lens that has a special texture, or colour and putting it on would make the pictures more saturated?
or maybe make a pair of glasses for people who can't produce as much cones as others?

my questions is because i can't really think of it, but what is colour saturation in terms of wavelengths, and is there a way to increase it in real life

no monitors or anything electronic(electric is fine), just physics
i'm interested

You would need a material which can amplify the intensity of light while it is passing through the material, before the light travels onward to be received by the eye.
A fascinating idea, but I think highly improbable material.
It would need to be supplied with an external power source since it is effectively acting as a power amplifier.

i have thought of that, and therefore i said "not electronic (but electric is fine)" but, i thought increasing the intensity of the light just changes the brightness of the image...

and that just makes everything look whiter, which is an opposite to increasing the saturation...
 
More light intensity equally across the spectrum would certainly result in the perception of everything seeming brighter.
However, the light at every wavelength would still be proportionally the same as before going through the device.
Red objects still would still be seen as red, and distinct from blue objects, though both red and blue objects would appear brighter.
Increased brightness would not result in both red and blue objects tending to become white, that would require additional wavelengths being mixed into the original light.

I think you would need to obtain separate RGB pictures first, then create a luminance signal by adding them in fixed proportions. Then to increase saturation, this luminance signal must be subtracted from the original image, presumably by out-phasing. Subtracting images used to be done in photography by placing a negative over a positive, and enabled image processing, such as edge crispening, to be obtained. So you could perhaps place a weak black and white negative over a full colour positive.

actually, the reason i wanted to ask, was to see if "saturationg contacts/glasses" would exist in the world, where you wear them, and things are simply more saturated, and look better
 
So everything looks like the photos in glossy celebrity gossip magazines.
Think I'll pass on that one.

as in, there are places in the world that are most of the time having overcast (namingly england), and as such, it's all gloomy, colours are tony grey, psychologically bad, so, here we add some lens, and it cheers you up

or just plain, easier version of dark vision, turn up the saturation
 
Or move to Portugal.

that's a nice contradiction ... by definition anything electronic = electric

Come to think of it, I think I remember reading about some kind of specs that had this kind of physiological effect. But I can't remember what it was called, or where I found it. I don't think it actually made colors more saturated. Just felt that way, for some colors.

I like weed too, but it's not this is not that kind of forum.

electronic is more of a sub-set of electric things,

ie, a solenoid is electric, but it is not electronic, but a IC controlled oscillation electromagnet is electronic
you get it? electronic=electric, but electric not equals to electronic

its an electronic device !stop fooling yourself and be prepared to learn some real information
There's a lot of outstanding guys on this forum that have been at electronics for many years

listen to them and learn some real world stuffDave
