HDR - Lens Correction profile not picked up in merged image
Merge to HDR, and the HDR image will not have the specific lens profile in it (in Lens Correction), even though this is there for the individual images being merged. It will of course always be the same lens. Seems to be a bug.

I just came here to check, if only I have this problem. I thought to myself, "I will just export jpgs and merge them". No. HDR merge doesn't work with non-RAW. I upgraded to 22 mainly for HDR and panoramas for drone photos, so I'm looking forward to update sorting this out.

The work-around until it is fixed is to look at the profile in one of the original images you are merging. Then in the HDR file Lens Correction profile, pick your camera and lens combination from the drop down list. A bit of a pain, but at least it will let you use this until there is a proper fix. Hope that helps.

Just Copy/Apply the lens corrections from a base image to the HDR dng.

The User Guide Help specifically mentions that Lens corrections are not currently applied.
In theory the merged files will almost always be using the same lens and so the same correction would apply BUT some of the corrections for the lens may vary according to f-stop, etc. and so it may not be entirely appropriate to always apply corrections automatically without reference to the photographer seek their approval.
On that point and as an observation for Wiktor 3 posts above, taking into account the apparent objectives of this development I am not at all sure that working with non -"RAW" files is a part of the current objective for this development. That seems to be a mature market that is already well saturated with processing tools and it is not clear how much more Capture One could bring to that party.

My current DJI drone is not supported by Capture One, so I had to create LCC profiles for my photos and I'm forced to use them because of huge light falloff and discoloration. I'm wondering how much using those LCC profiles after merge makes a difference. Maybe I'll never find out. ;-)

Wiktor,
That is indeed a tricky question.
In the absence of support for the drone lens you do not even have much of a starting point to experiment from. Your problem is probably not something that developers might expect to address and resolve as part of an initial release of the functionality.
How did you create the LCC profiles?

SFA,
I created LCC profiles taking pictures of translucent white plain mat plexi using sunlight for backlit. Had to repeat this to all build in resolutions and ratios to provide profiles to all taken pictures. Than I took those white pictures, analyzed them in C1 and saved every resolution and ratio as new LCC profile - done and working.
Before that I was trying to add masks and stuff and I was trying to create preset or style - it didn't work well enough.

I have really bad distortion in my merged DNG image. The lens I'm using is not supported but there is some type of correction baked into my raw file. If I merge the images it loses this corrections. Generic distortion correction does not fix the problem.

Boudewijn Boer,
can't you Copy/Apply the lens corrections from a base image to the HDR?0 -
Hi GB, no you can't. I tried copy/paste the lens profile / adjustments but this does not solve the issue. I use Panasonic S1 and the lens profiles are baked into the raw files. I things go wrong after exporting the file to DNG (which is what CaptureOne does for making the HDR).

Same problem with Nikon Z6..

Sort of 'happy' to hear you have the same issue with a Nikon. The support for Nikon Z6 is better than for Lumix S1 camera so hopefully this will be fixed in future updates.

Yes I hope so.. but I liked the HDR merging.. but without the lens corrections it's impossible to work with..0 -
Boudewijn Boer, S1 files should bring up the Manufactures profile in the C1 lens tool.
To get any correction the C1 sliders have to be at a non zero value with full distortion correction happening at 100%.
Just checking what you mean by "some type of correction baked into my raw file".0 -
@Ronald Zijlstra
Agree completely.
@GB
In an HDR, Capture One exports the original .RW2 raw files to a .DNG file. By doing so the raw file loses its embedded lens corrections. You can however select a lens profile afterwards, if there were any for Panasonic Lumix cameras. Capture One doesn't make lens profiles for these cameras because ... ironically ... the lens profiles are embedded in the raw files. Hence the problem. I can use the generic sliders but unfortunately it does not suffice to correct my Lumix S-Pro 16-35 F/4. Trust me; I tried...

"... the lens profiles are embedded in the raw files" yes, but they are not applied to the image in C1 unless you have set a value on the C1 sliders. So I am just checking first that you have set 100 on the distortion slider if you want full embedded correction that can be copied/applied later ?
I don't have the S1 myself but I downloaded a RW2 S1 RAW from the net and with the Manufactures profile and the distortion slider set to 100 I was able to copy the S1 lens distortion correction from that RW2 to a HDR dng I had created form Sony files, just to see if it can be done.
So I don't see why it is not happening with you.0 -
With the DJI Air2S, there is strong vignetting in the RAW files. I have used the PhaseOne LCC plate to create a preset that corrects this. I apply it during import of the DNGs.
I am happy to share this with anyone who would like it.
