Hello Affinity Team, do you have any response? Thanks!

Hello Affinity Team, I found some strange behaviour of the Affinity Lens Correction (so far tested for the Zeiss Batis 2.8/18). I did some extensive testing and came to the following conclusion: The Apple Core Image RAW Engine the distortion correction mimics the in-camera correction of the Sony A7III nearly perfectly. The Serif Engine does not... A substantial amount of the image is lost after distortion correction. (Best seen on the USB Cable on the Left However, if I change the scaling of the lens correction using (Serif Engine) to 98,5% and perform a crop after development to 6000x4000, the result gets really really close to the in-camera correction. I presume that the scaling was selected, so that the image has content all the way to the edges without cropping to 6000x4000. (The RAW has 6024x4024). However, at a 98,7% Scaling all 6024x4024 pixels have meaningful information, all the way to the edge corner pixels. So I wonder - why is the Serif Engine Distortion Correction unnecessarily throwing away information? I speculate that the difference comes from Apple using a manufacturer profile (stored with the RAW file) and Serif is using a dedicated/different Lens profile. I attached my test images (scaled to 2000 pixels, but the effect is still visible). Any ideas / tipps / help? For me this means, I need to switch on Apple Raw Enginge. What would be the disadvantage of doing that? Thanks a lot, Matthias

Hi Affinity, I found a weird behaviour. Obviously there was a bug saving my file to a network storage. Now wenn I open it, it first says "Your file was corrupted, but we found an old version" - Then I can see the file opened in Designer but immediately after that, it says "File is corrupted and must be closed now". How can I repair his file to recover as much information from it as possible. I can see that the information is in there, but Designer keeps closing it. Can you help me here? Thanks Karten.afdesign

First of all, thanks to the Affinity Team for the great tool. However, I also want to stress the point, that aligning to a key object is a basic feature that should be on the roadmap, well before advanced features. Best regards from Germany
