    Re: Phase one Profiles

    Barry here are some brief descriptions along with a white paper on how to use them.

    (excerpts from white paper by Walter Borchenko)

    Flash easy gray-This breakthrough technology
    profile neutralizes near neutral colors.

    Flash easy black -In dark materials like leather, subtle
    shades of black are visible to the eye but are unintended.

    Portrait natural - Processing files using the new Portrait natural profile will result in more accurate color, better saturation,better tone in skin transitions and better contrast for hair.

    Lance does this apply to the Plus backs

    Lance,
    Is there a link to this White Paper?
    If all I photograph is people, should I than only use the Portrait natural profile?

    Shame there isn't a profile that does all 3, they all sound like good things to have, especially as they seems to be targeting different parts of the histogram anyway.

    Re: Phase one Profiles

    That would be very difficult Ben. When you get into camera profiles, you usually battle between generating perfect color and generating perfectly neutral grays. The fact that differing light sources alter these relationships makes this a continually moving target. IOW, getting both at the same time is almost impossible, so you need to pick your poison so to speak. The good news is you can get them to be very close at the same time, at least under known or stable lighting; the bad news is if you need one to be "perfect" the other likely won't be, so you need to choose.

    The other part to a profile is the response curve. This determines total DR as well as overall and local contrasts in addition to the look to or balance of the total range of tones. Hence the need for different profiles specifically targeted to different results.

    If you open an image image in C1 then cycle through these profile options, you will see only subtle differences --- IOW they are all very good, just optimized toward one goal or another. Moreover, some of the differences are so subtle as they'll go unseen in an sRGB web jpeg...

    Cheers,
