Canon EOS R5 RAW: Cropping/aspect ratio ignored by Develop Persona

[ecureuil]

The Canon EOS R5 has an option called "Cropping/aspect ratio" that allows me to directly photograph e.g. with a 1:1 aspect ratio.

My understanding is that the aspect ratio is then stored as metadata within the RAW file.

The Affinity Photo Develop Persona seems to ignore this piece of information. Photographs are always shown in their full size.

My question(s):

1. Is there a setting somewhere in Affinity Photo that I haven't found yet?
2. If not, are there plans for future version of Affinity Photo to consider cropping information in RAW files?

No.

Serif does not comment on their future plans. 

However, much of this kind of info in RAW files is recorded in proprietary data formats, and Affinity Photo ignores most of it today. Unless they start supporting more of that information in general, it seems unlikely they'd support this specific item. But it's certainly possible they might, someday.

Canon is an interesting case because Photo incorporates some specific code for processing Canon RAW files, rather than depending completely on the support provided by LibRAW.

That would be reasonable, can you please post a 1:1 raw file to satisfy my curiosity?. This video

implies that the setting is an aid for composition which will affect a jpeg but a raw will be captured at full sensor size.  For what it's worth my LX100 captures raw images at 3088 square when set to 1:1

Here you go!

This is shot in a 1:1 square format.

I do not fully agree about the interpretation of "proprietary".

The information is stored in plain sight in the exif data.

Affinity simply ignores this information by choice / design. It could read this information if they wanted to, it is not encrypted or in any way protected. 

It reads some other information like AF sensors used, white balance, exposure compensation, but ignores most other.

As a Canon user, I don't understand why Affinity does not try to read picture profiles - the RAW engine will never develop RAW images in the way the user intended them. 

The most critical "Affinity did it my way" is not applying sharpening for RAW files. The forum is full of users stumbling about blurry files, wrong exposure in Develop persona. It would be great if Affinity would let the users choose (no sharpen, sharpen from RAW file settings, sharpen from App settings).
