Kodak SHO & GEM Plugins for Photoshop

Discussion in 'Digital Darkroom' started by davebecker, Apr 6, 2004.

  1. Recently installed both of these PS plugins on my PC using PS 7. I
    work with both digital camera and film based images and the problem I
    have is that when processing 35mm scanned slide images in PS
    the 'Kodak' name under filters is not highlighted meaning neither of
    these plugins can be utilized to process film based files (Tiffs).
    They work fine when working with digital camera based images which
    have been converted to Tiff. Any idea why this is the case?
    Appreciate your comments.
  2. image->mode->8bit
  3. Chris,
    Thanks for the quick response. So should I be scanning in 8 rather than 14 bit? My Nikon scanner provides both options, or simply make the adjustment to 8 bitin PS as you are suggesting?
    Thank you.
  4. I think the answer is to scan in 16 bit, do any photoshop operations such as curves or
    levels in 16 bit, where possible - I think Photoshop CS gives you more choices here - then
    only drop down to 8 bit when you have to. This does mean doing the SHO and GEM things
    relatively late in the workflow, but assuming you're not doing any really radical corrections
    with them this won't be a problem.

    The practical differences will be minimal in the long run - output devices are essentially
    only eight bit per channel - but the edge that 16 bit gives you in colour and tone
    adjustment is probably worth it, speaking as a slightly jealous Photoshop Elements 2
  5. Oops. substitute '14 bit' for '16 bit' in my last post and I'll make more sense and look less
    like a moron who can't read. :)
  6. image->adjustments->shadow/highlight

    This will do some of the same things and it works on 16 bit color images (your 14-bit scans).
