    Either would do just fine but I suggested red flowers because they're easier to find and DXOMark indicates that the red channel is weaker than the blue channel in the A6300. Donald is already avoiding the request, so I wouldn't hold my breath.

    It isn't, see how the red channel peaks in highlights for JPEG and in midtones for raw.

    Beautiful photos Jim.

    I'll take looking at good photos over discussing theory all day long. :)

    Mid tones? That's a strange claim, but it doesn't matter what "tones" they are in the image as long as they're a significant presence in the scene so it's easy to identify where they are showing up in the histogram(s). I guarantee you will learn something useful if you follow through on the test and post your results.

    116k .0035 accuracy im happy with that.

    I suggested blue because of its weighting for the luminance histo and the zebras.

    Your quote : Or even better, deep blue flowers.

    ive never seen a deep blue flower and apparently nether has google.

    Perhaps, but your skill as a flower photographer isn't the dispute. It's your claim that the A6300's in-camera live histogram is based on the raw data, rather than the RGB/JPEG data, that's being questioned.

    OK, but I picked red flowers (aside from the accessibility issue) because of the relative difference in WB co-efficients. Blue flowers will have a bigger visible impact on the luminance histogram but won't red flowers have a bigger visible impact on the raw and RGB histograms? Or am I missing something?

    ive already posted my comparisons. You have a camera do the test yourself, why take my word.

    what difference does it make when there is a scene surrounding the subject. there would be no usefulness of the histogram other than the 2 ends in these situations.

    i shoot all those they are not deep blue to me. light them with off camera fill flash fire across the surface is the way to pull texture detail from them.

    One more thing on which we disagree.

    Ok, I think we've done this to death. I fold and am out of this.
