Opening RAW file Affinity Photo results in "burnt" corners on photo


Recommended Posts

Opening a Canon (.cr2) RAW file (ISO 500) in Affinity Photo (V 1.6.7) results in corners that appear to be burnt out, as though by a bright lamp. The corners are black and then there's a bright white line that bleeds into the photo a bit. This is on an iMac running Mojave 10.14. It doesn't happen with every file. I can't predict when it will happen. The "burnt out" corners only appear when loaded into Affinity. They are not present when the file is viewed in Finder. It persists when I press Develop and are also there after I export to .jpeg.

Any help would be greatly appreciated.

AP 1.7 beta using Serif raw engine does the lens correction correctly.

I wonder if that is because in the beta the lens info includes "Unknown" but in the retail version it does not?

There might be better lens calibration data now available in an also more up to date lensfun database versions and so also a better distingushing between the Canon G7 (X) models ...

The beta is doing good lens correction despite the word "Unknown".

Which seems counterintuitive, at least to me.

You can try changing the RAW Engine in the develop assistant (icon looks like a waiter in black tie on the toolbar on the right hand side of the screen) to something else. Do this from within the develop persona and try reloading your photo. Barring that, let Affinity know and they can include a profile for your camera in a subsequent update.

Not on Windows, what the previous poster uses according to the screenshot. Changing RAW engines works and is available only under MacOS due to Apple's build in OS support for those.
