    Re: Which RGB Is Best For You?

    Good Morning Ron,
    I am slowly getting this, I think my confusion is my understanding of what RAW is.
    I thought RAW ment no WB and no RGB variables. You know RAW data, only ISO, shutter speed and f stop.
    Then you add all the other info in PP.

    What I am finding out is, the cameras settings for WB and RGB do effect your photo when shooting in RAW only.

    It looks like, I need a warm day to go out in the back yard with my camera, tripod and a notebook. Pick one colorful subject and just try each of these settings.

    I'm enjoying this discussion. Thanks for sticking with me.

    I think your original though was close to being correct. But the RAW does not contain ISO, shutter speed and f/stop, it has intensities that are the result of those settings. A RAW 'image' looks something like this (below) except that each pixel also has an intensity.



    Then based on the intensity/color of each pixel and of those around it, the converter renders this into an image using a mathematical transform (Bayer for the type shown). Your camera settings (WB, etc.) are used to initially view the image, because it has to use something.
