Default sharpening and noise reduction
Hi everybody,
I can't understand the reason why Capture One applies default sharpening (130 for my camera body) and noise reduction (luminance, details, color at 50, regardless of the ISO sensitivity) when opening any file ? It would be more logical to set them at zero and let the user chose the more convenient values.
I agree that it is always possible to get rid of these default values by creating presets or a user style (what I have done), but anyway....
Is there anybody who knows why ?
Thanks,
Robert

All is not quite as it seems, if I understand it right. You correctly say that for example the noise reduction is always set at 50. But my understanding is that C1 actually applies an amount of noise reduction based on the ISO, the camera model and so on, to achieve an "out of the box" result that may be about right. It calls the amount it has set 50 so that the amount the software has set is in the middle of the scale and you can go up and down from there. But the "50" midpoint of the scale on one image may not in fact be the same as on another image. It's just a label for the behind the scenes default noise reduction that C1 has applied to that particular image.
Sharpening I am less sure about, but I hope that helps.

Appearances can be deceptive: in fact, although the values on the sliders are the same, the amount of NR (and - less sure about this - sharpening) is in fact ISO dependent.It would be more logical to set them at zero and let the user chose the more convenient values.
Nothing illogical about Capture One doing it the way it curently does it, though: and given how good the defaults are, I actually think there's a lot to be said for the current approach.
Furthermore, Capture One always applies some NR, even when the slider is set to zero, and I doubt Phase One will change that, so zero NR is a meaningless construct in Phase One's view of the world.
Not saying I agree with the approach, but it does generally make for a better first impression of Capture One's image quality potential...0 -

Thanks Ian. I have had a look at the noise reduction applied to pictures at 200 and 3200 ISO (the highest nominal value on my body), and the values are the same : 50, 50, 50.
But,
@Keith
Thanks Keith, I didn't know that. Does it mean that the same noise reduction values depend upon the ISO sensitivity of the image ? And I didn't know that event at zero, some NR is applied. This means that we don't know exactly where we are and what we do ❓
And, so, I understand that Phase One prefers the users not to change the default values, as they give a better looking result in Capture One,..... for commercial purposes as opposed to a better control of the settings and adjustments 🙄
I would greatly appreciate more information about that from the Phase One staff.0 -
So if I set default noise reduction for my camera at say 40, will it always be 10 less than than what C1 has decided the required noise reduction for whatever ISO the file is. Or have I overridden C1's background calculation. 0 -

Yes it will always say 50, 50, 50, but my point was that 50 is just a label for the middle of the scale for that image. For a high ISO image, Capture One will have applied more NR than for a low ISO one, but it will still call the amount it has applied 50, so that you can adjust up and down from that.

Yes Ian, I should have read the online user guide prior to ask : what you say is written in all words 🤭 Except that it is not written that C1 applies NR even when the amount cursor is set to zero.
As far as sharpening is concerned, it seems to be more complicated that what we are used to with, for instance, Lightroom, as C1 applies an INPUT sharpening. I have read it in Sascha Erni's book. I have to digest a little this feature before going forward 😊0 -

I have been wondering about getting the book. Did you find it helpful?

Hmmmhhh.... Not really, I must say. There are indeed some "tricks" and information, but when you know Capture One and master it, it's not really helpful.0 -

Thanks. I had wondered whether that might be the case for me too as I have been using Capture One since version 4.

I've made my own NR settings for my D810's for each ISO value up from 64 up to 6400 and find that they produce far better results than C1's default settings and the same goes for sharpening, my own settings look better than what C1 automatically applies. 0 -
I am using specific settings provided through a German fine art printing magazine for my D4s, D5 and D810.
They have done lots of testing for Capture One and I feel pretty confident about their work.

From a week or two, I have chosen a preset for which sharpening and noise reduction are both set to zero. And I adjust them for each picture depending on what I see on the screen. I admit that it is not valid when you have batches of hundreds of files..... 0 -
@tenmangu81
I do exactly same choice, 0 for all and I adjust if necessary (often for my Sony A600, rarely for the Leica-Q)0
