Lens correction tool with lens movement
I use Rodenstock 32mm and 23mm lenses with shifts on technical cameras. These lenses greatly improve their view/look and need the lens correction tool/profile. The problem I run into continuously (in particular with the 32mm lens) is that the lens correction is not applied consistently between frames. The aim is to layer frames and it is here that I can see that the correction is not consistent. I can see that the lens profile differs between frames and often the crop registration is not consistently applied the same between frames. My workflow is as follows:
- I first do all my corrections and work on my "main" exposure
- assign lens profile and distortion slider to 100
- fill out the corresponding X and Y corrections that correspond with the shot
- copy/paste the lens corrections between frames. This with either within the lens correction tool tab itself or later in the tool tab bar and include additional corrections (like the crop).
Rarely is the first frame corrected the same as the subsequent frames that the corrections have been applied to. The subsequent frames are often the same but not the same as the original frame. Even when I reset all adjustments on the frames and copy in the corrections, will the lens correction be the same. I have tried this on multiple computers with no difference. I can send you two or more frames for you to test. This behavior has been going on through several versions of C1.I have a have an incorrect work flow do let me know. I would love to have this issue resolved. Thank you.

Thank you, I will send a request.

I might misunderstand you, but it appears that you apply same lens profile to all images regardless of lens shift position.

Hi Lukasz, yes correct. All three images have the same pov and lens corrections. Layer the three exposures on top of each other in PS and see if they line up. Best is to try your own resetting of the corrections and crop to check if you can get them to correct/line up the same. I hope you understand what I'm getting at.

As I understand all images have the same f stop and movement set in lens movement tab and are taken with the same shift. If so then definitely you should contact support as it appears a bug. I thought that problem is different lens position for each image. If you apply lens correction from primary variant to other variants all of them will have same lens correction applied, including mismatched shift position and f stop. For time being you can use ALPA correction plugin for Photoshop. I haven used it for years but it should still work.
Best regards,

Lukasz, you're correct—same images just different exposures. Communicating with you is not talking to support? Can you forward this link to support so I don't have to start this process over again? They should be able to get all the info through our conversations and sample images shared. So to be sure, you have been able to experience the same misalignments/correction with the lens correction tool? I used to work with the ALPA plugin before C1 was able to incorporate their plug-in into C1. Thanks for your help.

Sorry but I can’t see any link to sample images in your posts

Ah ok. I had made a case with C1 and Phase1. The images have been downloaded by Phase 1 under Case Number: CAS-00014228 CRM:0108000003819. Would that help? How should I proceed from here?

I would wait (reasonable amount of time of course) until they respond with some solution. If they don’t I would remind about your issue. So far I only had experience with handful of supports. Unfortunately I don’t have any experience with either Capture One or Phase One. From what I heard Phase One hardware support is excellent (cameras for 60k€ should have excellent support).

may i ask how this was resolved?

It never was resolved unfortunately since you/hardware support wasn't able to reproduce the misalignment. This keeps on happening and has been happening for many C1 versions. It mostly happens with the Rodenstock 32mm lens which does have barrel distortion and mustach distortions. It's hard to write about when you can't see it in person. This happens when several frames are layered on top of each other. The misalignment or lens correction does not copy over exactly the same.
