What problem do you see this solving?
I see a lot of dead pixels on Capture One Pro which is very bothering. If I zoom in, they are gone. Yes, I used single pixel noise reduction. I have no idea why it shows dead pixels but it's really bothering a lot as Capture One does NOT remove them when I zoom out. It should be a bug but I have no clues. I'm using GFX100S lossless files. It's not that visible from the screenshot but def too many dead pixels from my monitors.
When was the last time you were affected by this lack of functionality, or specific tool?

Current workaround
Are you using any workarounds or other solutions to achieve your goals in Capture One? Ignoring is the only solution. |
Hi 366733739077,
Will noise reduction be applied to that smaller preview image?
When exporting to a smaller image, my understaning is that you'd process to 100% then scale down. So, the preview will not allow you see accurately what the smaller files look alike.
(granted, the term "accurately" is only meaningful if you'd export to a size excatly matching your zoom level).
But I think a workaround (for the images where it really matters like the one from the OP or when unhandled noise is creating a color cast) is the softproof (recipe proof) function?
Create an export recipe with the intended scaling (e.g. 25%) for your preferred preview zoom level(s) and choose the preview zoom level 100%, then activate soft-proofing.
Question to Dennis:
Will this tell C1 to process the image to 100%, with all tools applied, and then scale down? It works only in zoom level 100% though, right? Or will the softproof activate all tools at all zoom levels?
At least with 100% zoom level and recipe scaling the softproofing allows you to see accurately what smaller files will look like, I think, I just cannot check it right now for the NR tool.
Btw, this also shows that performance is not a big problem as soft-proofing is slower than normal previewing but still fast.
So, an option in the preferences to switch accurate previewing on or off (OFF: like today, ON: scale to 100% then apply all tools, then scale down to zoom level) would give the user a good option (performance vs. accuracy), as it is more convienent and flexible (as far as zoom levels and switching between them is concerned but still having accurate rendering).
In Capture One you don't have fixed pixels, you have raw data that we scale and apply adjustments to after the scaling takes place.
We render directly from the raw file to the final output size, so the pixels don't exist until you generate an output file, which affects what details are present.
When you view at 100%, we are rendering the image as it will process at 100%. The same goes at 50% view and 33% view. At those smaller zoom levels, we are rendering that size file, not processing to 100% and scaling down. This allows you to see accurately what smaller files will look like.
When you are zoomed out, we are displaying a fixed size preview (you can choose the size in Preferences). This fixed size previews will have the details present when processing directly to that size.
This is done largely for performance. If we were to render the preview by processing to 100% and scaling down, performance would suffer dramatically.
Noise reduction is only applied at higher zoom levels, eg. 50% or higher. It is not clear to me if that zoom level is fixed or depend on variables like monitor resolution, performance of the system or others.
+1 but,
I would like to extend the scope of this request to allow the user to define at which zoom leve the whole noise reduction tool (not only the single pixels) is applied to the preview image. Especially interesting is the color noise as it can create a color cast if not enabled, with high noise images, in lower zoom levels.
