DNG Opcodes not supported

[pano]

When opening DNG files with opcodes, for example with the FixVignetteRadial command, Affinity Photo is ignoring them.

Adobe apps and Capture One are correctly interpreting these DNG commands.

Please check the attached file in Capture One / Photoshop and in Affinity Photo 1.9 (but I guess v2 is the same story). It's a bit exagerated, but useful to check if opcodes are supported.

Thank you

Well parsing & processing DNG opcodes needs to be mapped accordingly to equally available app functions and I doubt APh supports here such a sort of 1:1 from DNG to their internal function mapping at all.

That's very annoying... seems very standard functions that Affinity can implement like other vendors did.

..at least basic lens correction functions

APh probably relies here generally more to it's Lensfun library usage. And AFAIK it doesn't make any use of any in RAW files embedded vendor lens data adjustment settings (... since then Lensfun usually wouldn't be needed). - So I doubt it will behave different here for DNG files and then taking opcode based lens data settings into account.

But that's all just a guess from my side here, as I personally either way don't use DNGs.

Many industrial camera don't have lensfun profiles.. only embedded data in DNG files

Usually many industrial cameras (Nikon, Canon, Sony, ...) have the appropriate lens correction data already embedded in their RAW file vendor maker notes. And that's where apps like LR, C1 etc. do nowadays fetch the needed lens data from for image corrections.

This is a feature request suggestion that will make Affinity much better for users of DNG cameras, so many users.

Then you better post it into Feedback & Suggestions forum section, or maybe some moderator moves this thread to there.
