Thread: sharpening drum scans

    sharpening drum scans

    i need to apply some selective sharpening (photoshop cs - mac os 10) to some recent drum scans, i need to work carefully as the original negs are colour 400 asa and prone to get some nasty grain effect when applied in excess.

    does anyone have any favorite sharpening actions that work well?

    thanks again

    Convert to Lab, sharpen only the L channel, then convert back to RGB. In RGB you can try sharpening per channel but the problem is that it often creates some color artefacts; sharpen more the channel that has less grain. Also apply different sharpening to highlights, mid tones and shadows. Check your photo carefully after sharpening, you never know what it can cause.

    I'd buy Real World Photoshop for whatever version of the program you're using. A whole chapter on nothing but sharpening and it's all been useful to me for getting great, natural looking results. Most of it's a lot more sophisticated than what I'd been doing in the past.

    sharpening drum scans

    The DigiCam action produces allot of haloing. Something that I find unacceptable. I have a High Pass Sharpen Action that works in an adjustment layer. HPS to me works best with LF scanned images, because it sharpens the detail without introducing allot of artifacts. The sharpening can then be almost infinitely adjusted with the Opacity slider and by changing the Blend mode from Softlight to Hardlight. There is virtually no halo with this approach and the smoothness of LF tonality and edges are preserved even on very close inspection with a loupe. I usually do HPSA at my maximum print size. This usually 16x20 with 50% opacity in the Softlight Blend mode and let the Imageprint RIP downsample for smaller prints with no change in the settings (you do not have flatten layers for Imageprint).
    Thanks,
