Develop Persona, Quality for CR3 RAWs (noise, details)

[NotMyFault]

Hi,

as a lucky owner of a new Canon EOS R6 Mark II and RF 24-105 F4 i'm very disappointed with the RAW Persona results / image quality.

I tried to get a reasonable match bewteen the RAW and the out of Camera JPG.

If you compare both images (opnened in Photo, zommed 200%) and try to use most basic settings to get matching results, the quality in Photo is so much behind Canon JPG and DPP that it is effectively unusable.

1. Whatever you try, the noise reduction in Photo leaves ugly dark spots, unless you try extreme settings which remove all details
2. It is impossible to reach the same level of details. Photo is unable to provid the level of crispness the R6 is loved for

Both combined: Photo gives ungly noise, and looses all clarity and microcontrast.

The capture conditions of the test image are chosen to make this differences noticable. It is far less noticable in regular condition images (lower ISO).

Side nodes:

• I had to raise exposure in Photo by ~0.4 to reach same brightness
• Camera uses "Digital Lens Correction" settings which increases sharpness based on Canons secret IP of its own lenses. Results may be less different for 3rd party lenses (i will try later with Sigma lens).
• High ISO Noise reduction is set to "low" for test image (if i rember it right)
• Image uses ISO 25.000 intentionally
• All settings in Photo are to best match settings in Camera
• Picture Profile is "Standard".

Attached:

• Original RAW file
• Out of Camera JPG
• Scrennshot of both files opened in Photo, using Serif RAW on Windows PC

As a famous bloke once said, "If Photo were the only raw processor available I'd go back to shooting rgb files from the camera"
Oh wait a minute, that was me
Here's an alternative approach not using "Canons secret IP of its own lenses."
All defaults, no effort from me

Can't upload jpgs today so it's zipped

Thanks for your reply - but I‘m confused- the jpeg is below thumbnail in size, and where can I find the description of the approach?

I had a brief play with Photo V1 but the results were rubbish
Decent hardware deserves decent software

I totally agree. I hope that Affinity will undertake a complete overhaul of this RAW module and concentrate on that, instead of introducing new features. Quality is more important than quantity.

As this is quite an in-depth question I'd like to get a second opinion from @James Ritson I'll drop him an email and then reply back here once I have more info

Thanks
