Nikon D70 -- What are the actual color points for the sensor?

Discussion in 'Digital Photography' started by Chuck McDevitt, Aug 8, 2004.

  1. Maybe somebody out there can answer this. I'm trying to find out what the
    actual R, G, and B values are for the sensor in the Nikon D70. i.e. What's
    it's native gamut?

    A closely related question is: Does setting the camera's color mode to
    "II - Adobe 1998" actually record any increased information, or is it simply
    converting from a native sRGB to Adobe colorspace as a convenience for those
    who want to manipulate the image in photoshop?

    If the camera's native gamut is sRGB (or something smaller) there is no
    benefit in changing the colorspace in the camera, since you can change it
    after the fact. But if the native gamut is larger than sRGB, using sRGB
    would cause some color information to be lost.

    Given that the camera defaults to sRGB, I would guess that the sensor is
    aligned to that, but does anyone really know the truth?

    Good questions thanks for asking, I have benefited from your thought
    process, by doing a simple test I now know the answers.

    The native color space is specific to the camera; it is converted to sRGB
    or Adobe 1998 from that. The native color space is much wider than sRGB.

    Udie,

    Maybe not every one has the same experiment loving / exploring mind as
    you do. Would you like to share your thoughts on your experiments and
    maybe even you results?

    I would also be intertested to see if you did the same experiments as I
    did...

  6. Have you asked Nikon?
    Ask for the typical CIE primaries and whitepoint of the sensor used in
    the D70, and see if they will tell you. Do share if they do tell
    you...
