Default light falloff starting with fully corrected
Please give us the option to start with a fully corrected light falloff once imported.
At the moment every image starts with "0" light falloff which means that darker edges aren't corrected.
It seems thats it's not as simple as just creating a style with a value of "100" light falloff since the correction depends on the individual lens profile.
But I suppose starting at a corrected state should be possible if a lens profile is available. I think LR starts at a corrected point, too.
Thanks!

Lukas,
There are 4 types of Lens profile available in C1. Also LCC profiles.
2 of them are generic for use with lenses that have no profile available and/or are unable to identify themselves. So fo these all adjustments must be by user input and for each image in turn (unless a Preset is created and can be applied to multiple images at the same time.
If Capture One have developed a profile in their lab there will be a named file for the lens. This profile will take into account everything in the adjustment tool set that was considered to be necessary for correction at the time of assessment. It is likely that one or more sample lenses have been tested and that in some cases subsequent assessments have been performed on sample files as well.
Finally there are "Manufacturer" profiles which, for lenses that can deliver them, provide adjustment values as set by the lens manufacturer. These may or may not included light fall off correction depending on how the manufacturer understand the need for it.
In all cases, as I understand it, if there is no correction provided the slider will be set at 0. If there IS light fall off correction provided the slider will be set at 100.
I.E. 100% of the adjustment value provided has been applied (assuming default lens correction is active) but users have the opportunity to adjust that if they choose to.
So, basically, where there is a lens correction available for the light fall off (or indeed the application of the general corrections) the slider value will usually show at 100.
Which I think is what you are expecting. Perhaps it is the profiles for the specific lenses that need to be looked at?

"So, basically, where there is a lens correction available for the light fall off (or indeed the application of the general corrections) the slider value will usually show at 100."
This would be nice if it was like that but it isn't!
Here is one RAW file and the JPG for comparison: https://www.dropbox.com/sh/x42pclt30cpjifl/AAC1sWBN5NXh5S5wx0FMzfUGa?dl=0
Lens profile is available but after import light falloff is NOT at 100 but at 0 (with heavy vignette, wide open):
Does the RAW file show up with corrected light falloff when you import it?

Lukas,
If you change to the Manufacturer Profile for that lens do you see any difference?
The interpretation of the settings, as I understand them, is that there appears to be a Capture One generated profile for that lens BUT that profile does not include any adjustment for DIstortion, Sharpness Falloff or Light Fall off as applied to the image.
That is, perhaps, a surprise considering how your example screen grab presents. However the profile, if applied randomly to another image (non fuji, different lens of course) seems to offer very subtle adjustments suggesting it is not a profile that is having to do much work for correction. Maybe only the Chromatic Aberration setting was considered to be significant?
Also, for completeness, is it safe to assume that you do not have the Default Lens Correction function disabled?

You can download the original JPG+RAW from Fuji and JPG+RAW from Ricoh GR III here and see for yourself: https://www.dropbox.com/sh/x42pclt30cpjifl/AAC1sWBN5NXh5S5wx0FMzfUGa?dl=0
You should be able to see the heavy light falloff in the Fuji RAW as well as in the GR III RAW if you open it on your computer in C1. By the way, it's the same for my iPhone XS, too.
I don't know if there is a lens in which case light falloff is corrected but I've never had one.
On the other side I also own the Fuji 18mm F2 which has a pretty bad reputation. In that case at least the Distortion slider is at "100" but the light falloff still at "0".
From my experience Capture One has never corrected for light falloff automatically, even when a profile is available, and although the edges are far from fine.
As a matter of fact I've always had to pull the slider from "0" to correct the vignette. And no, I did not disable Default Lens Correction function.
Finally, I also found an old thread where the same problem was adressed:
There it is said:
"This is by design, as correcting it by default changes the look of the image considerably.
If you would like it changed, you are most welcome to file a Feature Request with our support team."I can only firmly state that starting with a RAW that is corrected for light falloff from the start would indeed be preferable!
