CR3 files are opening with "vignette masks" and circular highlights

[Xamora]

Hello!

I'm currently trying to edit some CR3 files from my Canon R but the files are launching with a black "vignette mask" already imposed on them and the outer areas have overexposed highlights. Not sure what's causing this or how to get rid of them. 

I just purchased Affinity 2 as I felt I was forced to upgrade from 1 as that's where I first noticed the problem but the mask was blue instead of black and I couldn't update the software. 

Any help is appreciated.

Hi @Xamora and welcome to the forums,

Are you able to upload one of the CR3 files exhibiting this behaviour so we can take a look at what might be going on?

I've seen this before where the individual was using an EF-S lens with a Canon mount adapter to mount it to their R body.  It displays OK in Canon DPP, but not in Affinity Photo.

You should be able to get rid of the vignette mask in the Affinity Photo Develop persona by going to the Lens panel and unchecking "Remove Lens Vignette".  However, I'm not sure whether they are any other issues as I use Canon DPP.

It looks like the RAW was opened without applying a lens profile / displaying the entire content of the sensor. – What if you activate lens correction and choose a profile?

[Xamora]

@- S - That worked! I did use an EF-S lens and unchecked it as suggested. *PHEW I honestly was beginning to think my files were corrupt somehow. 

@thomaso I tried using your suggestion but by default, it already had lens correction "on" and auto selected the correct lens. When I turned it off, the image slightly got "smaller", or had less of a "fish-eye" affect.

@Hangman Even though a solution was found, I attached an .CR3 file for you or anyone else to look at to see for yourselves what I was experiencing. 

Thank you all for your help!

FWIW, I tried the raw file in Photo and got a vignette like your example, except it was blue. However, it opens properly in the other three raw editors I have installed (ART, darktable and RawTherapee).

Does it work in AP if you try what @- S - suggested earlier?

Yes, disabling lens correction removes the vignette.

@Xamora I've used the lensfun data but changed the crop factor to 1. The vignette no longer occcurs and the correction matches Photolab very well. Hope it's of use
