PhotoShop CS Trial and Nikon RAW files

    I've been using PhotoShop 7.0 for some time and had no problems
    converting RAW files (NEF) from my Nikon D2H camera to TIFFs. Recently
    I got a trial version of Photoshop CS to see if I thought it worth
    upgrading to, and while CS opens and converts the NEF files to TIFFs,
    I find that the converted files from CS show artifacts rather like
    high-compression jpegs. This doesn't happen in PS 7.

    The effect is obvious on screen at 100%, and very ugly at 200%. It
    looks as if CS is applying some sharpening algorithm at an extreme
    level. Even if I don't use unsharp masking at all, the artifacts show
    up (they're not there in PS 7 even with unsharp masking applied

    Is there perhaps a buried default setting I haven't noticed?

    Any suggestions welcomed

  2. I just had a look, I must say I have s2pro RAF files, not sure whether your
    raw import screen is the same.
    If you click the small arrow right beside the Settings label and pulldown
    (it reads Camera Default here) and select preferences you get the option:
    Apply sharpness to All images/ Preview only. Is this what you are looking
    for perhaps ?

  3. Have you looked at the second tab (called 'Detail') in the CameraRAW
    dialog? That is where you can set sharpening. Perhaps this is set to
    some silly high value.

    Thanks to both responders.

    Yes, there was sharpening set by default - although not super-high. I
    reduced this to zero. Processing with that setting still curiously
    leaves a hint of artifacts compared to PS 7, but is certainly a much
    better result.

    Probably time I got Nikon Capture - when the Australian importer gets
    around to supplying it again (currently quoted as maybe available
    again in mid-August!).

    I've seen the same effect on some photos from my Canon. Try increasing
    the "Luminance Smoothing" in the "Detail" tab.
