    If shooting just RAW is there any reason to have in camera sharpening
    on? Seems sort of pointless to me.

    Most cameras record the camera settings and pass it along in the
    RAW-file as part of the EXIF Makernotes. If you use a RAW converter
    that understands this (the manufacturer's converter usually does),
    and ticks "As Shot", "Camera Defaults" (etc.) the camera's settings
    for things like sharpening will be used by default. You can of
    course override this, but I find it helpful as a starting point.

    Pointless it is. And the same is basically true of
    other adjustments to the JPEG. Do note that a JPEG is
    almost certainly still generated though, and is used
    both for viewing on the LCD and for generating a
    histogram. Gross changes to how the JPEG is generated
    might result in changes to the exposure metering.

    Better to have it off and a little more accurate histogram generated
    from the in-camera jpeg (even shooting raw).

    My camera will shoot RAW + jpg but I only shoot RAW. From what you are
    saying a jpg is still created for viewing and the histogram?

    For example, set white balance to 10000K (or the highest it goes) and
    take a shot, then take the same shot but with the WB to the lowest it
    goes. Compare the histograms.

    Yes a low quality full size jpeg is embedded in the RAW file. You can
    even extract those if you want.
