    Q.G., I believe You can be a bit more kind to fellow APUG members
    I can indeed.
    So can quite a few other APUG members, George.


    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.

    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.

    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.
    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.


    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.
    Well, yeah. Hence tri-color filtration.

    See also why insisting on talking about tri-colour when a B&W emulsion is concerned is nonsense?
    Eh?
    I do use a digital device in my photographic pursuits when necessary.
    When someone rags on me for using film, I use a middle digit, upraised.

    So if Boticelli chooses two colour to go together, it shows that he understands tri-colour theory?
    If RafaŽl 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.

    Q.G, there is a color aesthetics or if You like harmony of colors that is a confirmation.
    Boticelli, RafaŽl and other folks possessed the knowing how to do it. They weren't pulling it out of empty air...

    I was writing in the generality, but my comment stands as a "hot air-o-meter". Even if someone fancies himself as some kind of research scientist it is still helpful to give examples, and properly worked through logic etc. However the purpose of photographic technology is somewhat limited without a practical or artistic expression.

    You would think so. But... That's what this is all (the different threads this has surfaced in) about.

    Completely irrelevant it is here too.
    And when pushed despite of that, misleading and incorrect also.

    Duh...

    So you do not see what's going on.

    You don't see how yellow is not a mix of whatever two colours, but the colour a photon can have. A photon an emulsion shows a response to, despite it not being a tri-colour emulsion.
    You don't see that the tri-colour trickery has to be employed to differentiate between the colours, so you can use panchromatic B&W emulsions to create something you can perceive as separate colours.
    You don't see that it is all irrelevant, because we were not talking about anything like this. Until someone brought it up to give some 'relevance' to completely irrelevant comments.

    Round and round and round and round and...
    The going is remarkably tough on APUG today.

    Photons can have colors?

    Yes. They understood perfectly well how to use colour.
    So if you show me how to use colour, i don't have to study physics books to know what colour is?
