Export result look differently than the affinity photo

[yvanoid]

I tried to export in different export format ( ICC profile, pixel type, interpolation) and the problem persist everywhere (not pixel resizing, source photo is a raw). When I compare the result in photo app vs affinity photo (editor) it's not the same result, contrast are lost and colors also. See the screen capture.

If you could save the .afphoto file and upload it here I’m sure it will help to understand what is happening. Looks like a colour space issues.

[yvanoid]

That's why I tried with several ICC output profiles. maybe the profile is not working, or color space 32bit conversion, or some corrections not applied to the output, I don't know, but for me if the export gives a different result than what I see in the editor, it is not usable. I tried to upload the file but I received an error each time (see the image).

Thanks for your help.

Yes I saw same effect on your example on my iPad, but following this video, James explains that a conversion to sRGB profile would help and once I did that it did seem to make the JPG more true to what you see in Affinity.

First thank you Paul for your help.

As you see in my attached screenshots, the raw file uses sRGB just like the app configuration. I have already exported in sRGB for my test and for me something is not precise. Maybe my iPad pro 12.9 M1's new display is too precise for dark tones, but the difference is big for me and makes the app unusable. I love the app so much, but I checked the same file with pixelmator and I don't have this problem. Sorry, I don't like to mention other software, but it's for comparison. it will be good if a solution or buf fix can be found.

best regards

I am confused maybe someone else may know much more about this than me., When I select convert document it appears to  show the existing format as being RGB/16 with an Adobe RGB (1998) profile. Whether this what you expected I am not sure.
 

[yvanoid]

I don't know why the channels say sRGB and the document conversion says adobeRGB. But my Lumix S1 camera setting is set to sRGB. I tried to convert the document to sRGB and I see the same result as the export, I lost the black tones. it is normal when changing the profile not to have the same result, but I have the impression that the conversion loses too much. This is not the first photo where I observed this problem that the exported version was worse than the one modified in the editor. what I don't understand is that my camera is in sRGB, the preferences of afinity photo are in sRGB, my exports are still in sRGB. normally it shouldn't need the profile conversion because everything is in the same system. I don’t known where affinity photo take the adobeRGB. if I understood correctly I should convert my documents to sRGB before my corrections to have the right result at the end. in short, i have never needed to convert a document with my raw files on any other softwares LR, photoshop, etc ... i still have the impression that there is a bug somewhere.

thanks for your time Paul.

Your camera setting applies only when it produces JPG images, not RAW images.

[yvanoid]

Thank you for the answer.

But do you know why Affinity Photo generates a document in adobeRGB (for raw files) when the preference (Default RGB profile) is on sRGB ?

Do we have to change the document to sRGB each time I open a raw photo to have consistant export result ?

Do you think the difference in black tones is normal when I export ?

 

best regards,

After checking it seems that the raw files imported by affinity photo are always in adobeRGB. What is annoying with this is that all the adjustments in the persona develop in raw cannot be exploited because you have to convert the document to sRGB in order to have a consistent result in the export.

The workflow that works for me involves having to go back to persona photo after opening the raw file to convert to sRGB and then go back to persona develop to make adjustments. If I make my adjustments with this workflow the export is consistent. It would be convenient if affinity photo would use the profile in preference for raw files instead of forcing adobeRGB. Still, at the end of the day, I always have the impression that there is a problem with the profile conversion.

How are you checking this? I can’t find any colour profile info in Raw mode?

Have you set Settings Colour Convert opened files to workspace?

 

[yvanoid]

Yes the option is checked see the attachement. 
* I re-imported my raw file at some point because this option was not set, but the problem persist.

 

At some point you have to switch to Persona Photo and from there you are in adobeRGB.

 

You can validate as Paul demonstrated above.

thanks for your help.

So, your workspace is currently set to sRGB and affinity is 'assigning' adobe workspace to your developed file? That’s odd given the setting shown.

When you first open a file with a different workspace you should get a pop up message saying you files workspace is being converted….. do you see this?

What make a model camera are you using to create the RAW files? 
Have you tried another RAW file from a different source to see what workspace is assigned? 
Have you tried setting a different default colour space to see what happens?

 

[yvanoid]

The camera is Lumix S1

This test workflow answers your questions.

1. I open my raw file, Affinity Photo displays RAW at the top in the Develop persona.
2. I tap develop, and I arrive in persona Photo. I open Convert document to see the current profile. Affinity indicates adobe RGB. I tap cancel to convert nothing.
3. I close the file, and I open it again and I have the conversion to sRGb with the popup.

if I skip the step 2, I will have the popup the next time I open the document.

The problem is that if I don't do step 3 and do corrections in step 2 without converting to sRGB,  I remain in adobeRGB in the Photo persona without knowing it and the corrections will not be precise when converting to srgb. Moreover like I said the treatments done in Persona Develop (raw) are not useful because the conversion of the colorspace adobeRGB to srgb changes the black tones. I really like the software, but for me the Develop Persona in RAW mode is disappointing and profile conversions. 

Now that I have found a way to achieve the right result, it is good, but I must admit that it is much simpler and more precise in terms of results with other products.

 I made a video that shows what happens in attachment.

That’s the 'odd' bit. I would expect the default settings to be applied🤔.

What settings do you have in Assistant menu? 
Have you tried changing the RAW engine (Apple/Serif engines)?

If the cameras not applying a workspace, and your settings are all sRGB then it suggests a bug in Affinity. Perhaps the Moderators will have an answer?

Me too.

Never tried.

I think also it’s a bug. I think also the profile conversion is not correct or maybe the conversion 32bits to 16 or 8bits can lost black tones.
 

thanks for your help DM1!

I must say that the Affinity Photo community is very active and a great help.
