Serious Raw File Color Bug for Photography

[Jiho Lee]

Camera: Panasonic GH4

Mac OS Version: 11.2.2.

Affinity Photo Version: 1.9.2

------------

Affinity photo ruins Bokeh and color of Raw files.

I don't know why... The program changes something automatically that I do not intend.

Whenever I import Raw files into Affinity photo, Bokeh and color are ruined automatically even though I do nothing.

Other basic program on Mac shows same, but only Affinity Photo shows difference. 

When I changed Raw file to TIFF on Mac and imported it into Affinity Photo, there was no problem on TIFF. Same Bekeh, same color, same look that I can see on other programs.

Only RAW file has a problem when I import it into Affinity Photo.

Any thought? help? Is this a kind of bug??

I would lower the contrast in the Affinity RAW develop persona for a start.

Hi @Jiho Lee,
Welcome to Affinity Forums
I remember having seen a couple reports of similar issues with the purple contaminating RAWs opened it Affinity in similar contexts (blues and bokeh/highlights). Do you mind attaching the original RAW shown in your screenshot so i can add it and update our report (or fill a new one if required). Thank you.

Sorry for late.

I just check this out right now.

I attach the RAW file I mentioned as you asked me.

And I want to add one more comment.

I changed my camera from Panasonic GH4 to Canon EOS RP. And I experience similar problems with Canon RP's RAW file, which is that something is changed and different with other programs when I import RAW files into Affinity Photo. I hope this would be helpful for you to fix the problem.

Thank you for your work and I will wait the update day!

Hi @Jiho Lee,
No worries. Thanks for the file. There's indeed a few reports of similar issues with other cameras. I've added your file/updated our report with the info you provided. Thanks for your support. Much appreciated.

Hi,

for Canon RAW files CR2&CR3, it is next to impossible to get identical results in Affinity Photo, unless you  select the “Picture Style” neutral, and modify its settings to reduce sharpening to 0.

When using any other Picture Style, especially Auto or Standard, in-camera JPG will always severely differ from Affinity’s output, and it is next to impossible getting similar results (to Canon’s automatic) with manual adjustments.

In addition to picture style, you would need to strictly keep settings influencing image capture to off or zero, except exposure compensation and White Balance. Affinity Photo ignore nearly all settings when opening Canon RAW files.

Some “ignored” settings are:

• Picture Style (sharpening, Hue shift, Saturation, Monochrome, Color Filter, ...)
• Highlight Tone Priority (unsure)
• Auto Lightning Optimizer
• Digital Lens Correction (Refinement based on object distance, Dual Pixel, ...)
• CA Correction in Photo is sub par to Canon

Settings read by Photo:

• Exposure Correction 
• White Balance
• Basic Lens Correction (Barrel, Vignette, ...)

Your information is helpful for me to use my EOS RP. 

Thank you!

And back to the original question, I just mentioned about RAW files, not JPG.

The problem was "Same RAW files, different Output in Affinity Photo with other programs".

Other programs have the same result when I import RAW files into them. But Affinity Photo has a different result with the same RAW file.

Anyway, thank you again for your comment! I could understand how Affinity Photo program operates.

When I use blue filters (80A or a 47) the jpegs are okay but the nef raw files lose contrast and highlights become magenta.  Any ideas.

Hi,

Is this somehow solved?

I have the same problems.

Hi @Seweryn,
No, sorry. There wasn't progress here yet. Can you attach a sample RAW from your camera showing the issues you're experiencing to add to our log please? Thank you.

Hi,

Photos are uploaded: https://www.dropbox.com/request/Engu0X17MkJkULxdHfiY

I am using Affinity Photo 1.10.4.1198 on Windows.

The problem is that somehow photos in NEF format are more RED, or they have strange RED artifacts.
Especially, in my case, I did them in 1600 ISO, so it might be also bug reported in (*).

You will see screenshots from: Fast Stone Viewer (free tool), Light Room and Affinity Photo. Displaying is getting worse in the same direction as listed here.

I have not very strong theory, that in fact green color is shifted to the left, at least I have such a feeling by looking at histograms, but this is not scientifically confirmed.

So the dominance of the "red" is only an optical effect.

And those errors are nor possible to repair by simple levels, gamma changes or white balance changes.
As well as decreasing of the clarity does not help at all as it is not really noise, but shifted to red areas.

If you need more examples, I have a couple of more shots like that.

Thanks in advance and regards,

Seweryn.

Thanks for the files @Seweryn, much appreciated. This seems indeed the same issue we have logged previously. It's not clear what's going wrong here but it's not limited to NEF files. Some RW2 and ARW files also present similar issues. I'm passing the files to the dev team and updating/bumping our report to bring this up again to their attention.

[Seweryn]

Hi,

Thanks for the feedback.

I am happy to help you.

Best regards,

Seweryn.

I am getting the exact same thing.  I did some UV glow photography last night.  When I look at the images in photo viewer, they look great, but when I import the raw file into Affinity, the colors look exactly like the bokeh example above.  Now, I need to import my raw files into Photoshop or retake in JPEG.
