  • Sharpness

    Hi!
    I noticed that the majority of pictures were more sharper with Capture One than with Acdsee (default settings).
    I tried to obtain the same result, and I think I was able to do it, with the following parameters (for landscape, machine, building...). See the screen shot.

    100% seems to be excessive, but I have the feeling that the Acdsee sliders are not so "effective".

    What do you think ? What about your (default) settings ?
    Thank you.

    ACDSee's sharpening sliders do not behave like the similar ones in photoshop or Capture One. I have never been able to figure out a direct equivalence. For instance the Rayon setting are integers, in photoshop they can be small fractions. So by experimenting, depending on the camera, the ISO etc, I START with

    Quantite: 45
    Rayon: 4
    Masque: 5
    Details: 50
    Seuil: 5.

    For noise reduction my defaults are
    Luminance: 8
    Intensite: 8
    Couleur: 8
    Conserve les informations: 0
    Seuil de Conservation des informations: 85

    These are for an Olympus OM-D Em-1 usually at ISO 200 RAW files. For most files I don't need to do anything more.

    I think your noise reduction is very aggressive which is why you feel that the sharpening isn't doing much. I approach noise reduction by moving BOTH Luminance and Intensity to 100%. Then I adjust the Couleur to remove some colour noise, usually I need no more than 30%. THEN I back off the Luminance slider until I just begin to see noise again in the image - usually less than 30, the back off the Intensite to about the same level or less. Play with this as a technique and you'll find what works best for your particular camera.

      It's a funny coincidence : I have just bought this Em1 - M2 ( alternative to the cumbersome D810...), and it's with this camera (+12-100mm) I tested sharpness...

      I agree that your parameters are very good... except for "couleur" : 8 is (for me) often not sufficiently. But, strangely "your" image has un greater impact : undoubtely, my "luminance" at 30 is too high, and that ruins the 100 of the sharpness.

      Anyway, your parameters are more reasonable. I was aware something was wrong in mine...

      Thank you for your advice.

        My current workflow is to first set the mask on sharpening while holding the alt key so its only applied to desired areas. Next I'll do the same for preserve detail/preserve detail threshold. Then I'll zoom in to 400% to see the effects of changes at the pixel level and start by adjusting sharpening amount, beginning at 25% and moving up until the image becomes clearer. Then I'll adjust the radius to increase contrast to the point that it appears sharpened but without introducing haloing. Finally I'll adjust the detail slider which only affects the brightest pixels; I find this is the setting that can really help a photo pop without appearing overs-sharpened. I rarely use threshold, but there are certain times that it can be helpful to avoid over-sharpening. Next I'll work the noise reduction sliders, starting by increasing the luminance to the point that it begins to smooth out noise but still retains sufficient detail. Then I'll adjust the strength upward if the image is particularly noisy, but generally leave it at 0-5 and rarely push it much past 15. From there it's a balancing act, making small adjustments to sharpening/noise reduction and viewing different parts of the image to make sure the desired effects are uniformly applied. When I finally zoom back to 100% I find that I'm usually very happy with the results and my images are sharp without overdoing it.

          Thank you for sharing your workflows - it will help me to be more consistent I think, and I will see if this helps me.

          Do you mean that you use the Develop Brush in Develop Mode, or are you talking about a Sharpen layer in Edit mode? What does the Alt key do? I tried it but couldn't see what it does.

            in Develop Mode, section "Details" - "Sharpen". If you click onto the "Mask"-slider und push and hold the "Alt"-key, you will see a high-contrast bw-mask which shows you the areas sharpening will afford. By sliding "Mask" you can vary these areas.
            Same effect at "Noise reduction" - "Preserve Details".

              Thanks Uwe - I had accidentally seen the mask before, and assumed it was a bug in ACDsee or my graphics drivers!

              Being able to see the mask will make it a lot more intuitive to understand adjustment effects now

                May I suggest a rather radical solution?
                Switch both sharpness and noise reduction off (for low ISO files)! Compare your results to your prior results and ask yourself if you can't live with the little less perceived sharpness. Actually sharpness adds something to your file that wasn't there in the first place, noise reduction takes something away from your file. I usually only sharpen before printing and apply that in my prinitng app (Qimage Ultimate). A little sahrpening may also be needed when resizing for web usage. But I think the so called capture sharpening with today's cameras and lenses is way, way overrated.

                  Sharpness at zero... Why not ? You are right in the sense that, yes, the image often is more nice to look at, because more soft. That does not show stair step artifacts. Of course, it depends on the image type, it depends how far away you look at the picture... This « value » must not be overlooked.

                    Capture One is fantastic on details. I'm not sure, it is just sharpening, but the results are great. I still prefer ACDSee Pro overall, but details are not as good on default.

                    Your setting is surprisingly good. No artefacts and very good sharpness and details. A problem is the 100% on colour noise reduction, because it causes heavy desaturation on some parts of the image (see picture). And some small structures could be lost with the noise reduction as well. I would suggest smaller numbers on the noise reduction. I will safe a preset and try your setting next time I develop images.

                      OK SCX. I look forward to your comments with interest.
                      For «colours», so far, I was never very receptive to the effects. I will look at the matter...

                        In Acdsee 2018, I find that Detail / sharpen action (+1) works fine, particularly for landscape and architecture.
