    Just tested with Detail set to default. I have not seen any increase in crosshatch.

    I would Black shade if your ambient temperature changes more than 15 degrees Fahrenheit over the course of your shoot or between your current shoot and previous shoot. Up or down. I'd also let the camera warm up for at least 15-20min before blackshading.

    I don't work for BM obviously but this seems like generally good practice.

    I'd also do it for high speed work - 60Fps or higher... not sure if it cals all speeds with one blackshade, but generally if you are doing more than 2x standard frame rate it can't hurt (i.e. 48, 60, 120) if 24 timebase.

    Some RED operators black shade their camera every time they turn it on.

    At ISO 1600 perform black shading has less noticeable FPN at that setting than black shading at ISO 800 and increase to ISO 1600. Looks like this calibration might be needed everytime the ISO is changed.

    Only had time for some quick tests last night, but this looks very promising! The blue lift in the shadows is all but gone, and the crosshatching seems much less visible, to the point where I can actually consider using ISO 1600 now!

    And although most of my shooting tends to be ProRes, here are a couple DNGs:

    Firmware 4.0 - https://app.box.com/s/26ev814mg6vzc028sq5kmmxrs35jy0s7

    Firmware 4.2 (after single black shading calibration) - https://app.box.com/s/2e0xql6su1j8xqhh0la56jepow45uxu2
