I believe somebody's colour photographs says a lot.
Absence of such tells a lot.. as well
Q.G., I believe You can be a bit more kind to fellow APUG members
I would love to hear your explanation why someone making colour photos equates to understanding the 'underlying mechanism'.
But let us turn this thread back to that other colour, Big Yellow.
But the person who designed that emulsion does.And what you and PE are not understanding is that an emulsion doesn't care about how you might see colour when it responds to a stimulus produced by being hit by a photon from the 'yellow' region of the spectrum.
As I've said, PE was explaining it as it relates to color photography. Where has he said it explains all color phenomena?The tri-colour colour theory is all well and fine. If and when it is relevant and appropriate.
Insisting on explaining all colour-phenomena by reverting to some tri-colour mumbo jumbo is silly and a show of real ignorance.
Well, yeah. Hence tri-color filtration.If you want it to make a difference between the different colours, you will have to devise a way to make that emulsion or sensor "sense" only those colours you want it to.
Eh?See also why insisting on talking about tri-colour when a B&W emulsion is concerned is nonsense?
Because showing you can apply whatever understanding you think you may have to a real-world photographic situation gives some degree of insight into the thought processes and motivations of the individual.

When will you begin to truly get a grasp of this thing called colour?
Q.G, there is a color aesthetics or if You like harmony of colors that is a confirmation.So if Boticelli chooses two colour to go together, it shows that he understands tri-colour theory?
If Rafaël has a different palette, that shows his understanding of the physics of colour is different too?
Can you spot the problem with such a believe? I know i can.

As I've said, PE was explaining it as it relates to color photography. Where has he said it explains all color phenomena? "Tri-colour mumbo-jumbo"? First, it's not mumbo-jumbo. It's very easy to understand. Second, look at the spec. sheet for any color film and you will see the tri-color method applied. As you know, I'm sure.
Well, yeah. Hence tri-color filtration.

Boticelli, Rafaël and other folks possessed the knowing how to do it. They weren't pulling it out of empty air...
Photons can have colors?
You don't see how yellow is not a mix of whatever two colours, but the colour a photon can have.
True.
But so what?
Pain too is just product of our minds. Yet you sure know what will happen if you hit your thumb with a ten pound sledgehammer. Even though pain is not being hit on your thumb with a ten pound sledgehammer, but entirely a product of our minds.
We can play this realist vs idealist game all day, and it doesn't make one iota of a difference.
There is a correlation between our perception of colour and wavelengths of light.
Just as there is between that hammer landing on your thumb and the pain your mind produces.
This is something I was deliberating over when I was setting up my tri-colour LED light source.
I was trying to work out if the light output when I use the red and green LEDs is actually yellow or if it is still red and green (separately) but our eyes perceive them as a single yellow source.
Oh, so the color of a photon depends on the detector sensing it?
Otherwise they just have an energy/wavelength/frequency, depending on how you want to think about it.
Go away a few minutes and see what happens?
Actually, yellow in film capture consists of 2 photons with a Green energy level and a Red energy level, or one photon with an intermediate energy level between Red and Green captured in 2 layers. No photons with the Blue energy level are allowed. They are filtered out.
The same is pretty much true with the eye and in nature.
Who said that?
It's that correlation between their energy and how colour sensitive thingies treat them again.
That's 'anything goes' talk.
What's energy then, apart from whatever you want it to be?
Then let me present you with that same question i have put to you a number of times before. The question you have avoided answering:
How do you explain the fact that emulsions are not blind to sodium light?
Blatant nonsense, your two photon/tri-colour theory.

Blatant nonsense, your two photon/tri-colour theory.
If you look here: http://en.wikipedia.org/wiki/Sodium-vapor_lamp you see the spectrum of Sodium vapor at 600 nm. If you look at Kodak's web site here: http://www.kodak.com/global/en/professional/support/techPubs/e4050/e4050.pdf you will see that film typically has sensitivity at 600 nm. That is how a film can see the light of a Sodium lamp.
