C1P 15.1: HDR creation unnecessarily bakes in default crop

Already opened an issue for this but haven't received any response yet in a week, so I'm posting this here as well for added exposure…

As of the latest update, Capture One Pro unnecessarily bakes in a default crop when creating an HDR composite.

What I mean by this is that if you have an image that, due to lens corrections and/or raw overhead (?), has a “spare” margin around the (soft?) crop C1P applies by default (that you can expand the crop into when manually cropping), creating an HDR bakes in this default crop when creating an HDR image as of the update, ignoring any explicit crop set on the source images. This is to say, the resulting HDR image has a smaller canvas than the source image; specifically, it fixedly is what the default crop of the source images was.

This wasn't the case previously, is completely unnecessary and unnecessarily reduces the canvas compared to what you could get out of a single source image (of course depending on image attributes such as focal length vs. lens corrections — for my Olympus images, this is most noticeable with wide-angle shots (12-40 f/2.8 lens towards the lower end)).

I could live with C1P “baking” a crop manually applied to the source images into the resulting HDR (the way it now does with lens corrections), but not with the crop applied being the default crop with no way to change that.

I completely agree. Cropping the HDR DNG files is a big problem. Where C1 normally has an advantage over Lightroom, as more of the image data can be used when fixing the perspective and cropping – i.e. a bigger crop is possible – now it has a big disadvantage with HDR files, as C1 users lose part of their photos compared to Lightroom users (C1 crops more image data away).
This issue has annoyed me since the beginning, and might lead me back to Lightroom. I am very surprised so few other users have raised this issue.

However, I just found out this default crop can be avoided by choosing Disable Default Lens Corrections in the Lens Correction Panel, selecting the Generic profile for all the images of the HDR bracket and setting all the sliders to 0. This will create a HDR image without crop. After applying a lens profile to this DNG file, it will have the same dimensions/crop as a RAW file with applied lens profile.
Normally one always applies lens profiles at the beginning, but this is not advisable for HDR files in C1, as data will be lost.
