    Guy Kuo, (ovation software, AVIA etc.) posted this example of CR.

    Mr D what do you feel about this example, especially with regard to what you would consider in terms of intensity being important
    important. Eash shot shows a progressivly decreased black level.

    I feel representationally 300:1 is sufficient to show a video intensity scale. The only advantage to a greater contrast range is that you can spread these intensities out if you like. However as long as you've got enough room to avoid mapping them onto each other you would probably not feel disapointed if you viewed 300:1 in isolation. You will not see any more differentiation in the image compared to the one at 1000:1 or 3000:1 ( I reckon the 3000:1 looks a bit clipped or at least crushed in the blacks to be honest)
