Fujifilm RAF (RAW) files incorrect color reproduction in Affinity Photo

[BorisFuji]

I recently purchased Affinity Photo, when I use RAW files from my Fujifilm X-T4 camera the colors aren't shown correctly in Affinity Photo. Sometimes white is showed as bright blue and red is green. I've attached an unedited photo opened in lightroom, the scene was slightly yellow in real life from the street lanterns. Does anyone know how to fix this? I've attached the RAW file as well if you want to try it out for yourself.

 

I've tried to disable hardware acceleration, doesn't change it.

Your camera is supported, but states...

"FujiFilm X-T4 (uncompressed and lossless compressed only)"

Do you know what compression setting you have set?

FWIW I downloaded your file and it looks OK. Has a yellow tint but much more subtle than yours. Are RAW files from other manufacturers OK?

Not much color in the photo to work with, once the color cast is neutralized. This is what I came up with. I was going to upload the afphoto file, but for some reason it ballooned to over 400mb, and my internet speed is just to slow to try to upload files that size.

Do you have a camera specific software, made for processing Fuji RAW files? Do your RAW files show the same strong color cast in it? I'm thinking that White Balance may not have been set correct in the camera.

@BorisFuji Welcome to the forum.

There may be a colour processing issue with APhoto:

• The right hand version is the result when the file is loaded directly into APhoto
• For the left hand version I pre-processed with file with Iridient X-Transformer and then loaded the resultant DNG file into APhoto

Both files have been developed without any changes.  Note also the colour change of the out-of-focus lamp.  This may be a result of the intermediate processing steps - the camera, Iridient (although I'm not inclined to think this), or APhoto. I have seen issues reported here on the forums with Fuji cameras and blown-out highlights going magenta.

There is no White Balance information in that file according to the Metadata tab in Develop.

[David in Яuislip]

I think it's a white balance issue but that's a pretty challenging image

Whilst I don't use APhoto to develop raw images in this case I think it's done a pretty good job regarding colour, I haven't looked  at noise

[RichardMH]

There have been some updates to the RAW processor in the beta. Maybe try that?

The RAW processing engine in AP has a lot to be desired. Comparing to the image I previously posted, here's what LR, an old version was able to do. I did have to convert it to DNG before LR would accept it.

The issue is with the colour temperature of the RAW file  I have tested your file in other photo editors and they have the same yellow tint on the image if you use the following white balance adjustment it will remove the majority of the tint.

[Old Bruce]

But what about the fact that the raw file has no White Balance information in its Metadata? Is that not a problem?

Well, Affinity shows no WB metadata. Someone with access to other RAW developers or exiftool might check if it really missing, or just not read by Affinity.

Here's an exiftool dump from the file

It seems the blue channel is far off from Standard - matching what DWright explained.

White Balance                   : Auto
Saturation                      : None (B&W)
White Balance Fine Tune         : Red +0, Blue +0

WB GRB Levels Standard          : 302 370 861 17 302 628 488 21
WB GRB Levels Auto              : 302 342 1311
WB GRB Levels                   : 302 342 1311

I have same issue with RAF (uncompressed Fujifilm RAW files) processing from my X-T3. Affinity Photo shifts colors to yellow extremely and I am not able to tune picture close to jpeg produced by camera (AP 2.0.4 on Mac OS Ventura 13.2. On attached picture there is RAF opened in Affinity Photo on the left. Top right is jpeg produced with camera with Provia/Standard setting. Bottom right is RAF opened in Dark Table - much closer to camera jpeg. Best result I have with Fujifilm RAF Studio app. But this is not very comfort way because camera must be connected and switched on during conversion.
Does anyone know what I am doing wrong with Affinity Photo? It is in default settings now. Or is this a bug this strong shift to yellow?
Does anyone same or better experiences with RAF procesing in AP 2? It seems to me hardly usable or unusable now with default settings. Does anyone know what to do to have better results and better starting colour quality after RAF is open?

Thank for any advice.

Hi marrtinr,

Welcome to the forums...

Are you able to upload the RAF file so we can take a look (you may need to ZIP the file first for it to be accepted)...

One thing to try is to disable Apply Tone Curve in the Develop Assistant Preferences in Photo. You can also try switching between the Serif and Apple RAW engine settings in the same dialogue and then reopen the RAW file and see how that affects the results you see...

[RichardMH]

One option is to use the free Capture one Express for Fujifilm to do the raw conversion and send a tiff to photo. Iridient X Transformer is another option but its not free. 

I've used Capture One Express for Sony quite a lot in this way as it handles highlights better than Photo.

Thanks for reply. I am attaching zip with RAF and also desired jpeg. Trying disable Tone Curve has no effect and result still tends to yellow. Switching from Serf RAW engine to Apple RAW engine give result much closer to desired jpeg. Still not perfect but much better. Fujifilm RAF Studio app is still better choice when I have my camera with me.

Thanks for your advice. Sure I'll try Capture one. Hope it will be good solution for editing when my camera is not with me and Fujifilm RAW Studio is therefore unaviable for me.
Pity that Affinity Photo handles RAF imperfect. I thought upgrade from ver. 1 to ver. 2 give me all in one tool. Even so I like Affinity apps.

[RichardMH]

FWIW Photo 2 with develop assistant settings all take no action and some editing. I use ROM RGB colour space and its a wide gamut monitor. Remember in camera jpegs have some processing so may take some playing around to match them.

Thank you guys for your comments. Just now I am playing with Capture One Express and results are really great.

The in-camera processing is magic and you need something as good from a desktop RAW converter.

I agree at all
