Colours changing on exporting

[peterhammer]

I edit a document in Affinity Photo 2 with sRGB colour space.  When I go to export the document as a jpg the PREVIEW image is less saturated and darker.  The actual outputted image matches the preview.  Hence it has nothing to do with the monitor calibration as EVERYTHING happens in the Photo application.  There is NO change of colour spaces so it is hard to see how that is an issue.  This doesn't happen when I use Photo version 1.  Can the bug please be fixed asap?

I cannot replicate this. Are you using File->Export, or the Export Persona?

The only bug I found was in the File->Export panel, down in the Advanced selection.  If you don't use a preset, the ICC Profile box can display a random profile. I got AnimePalette, a profile I've never used. Perhaps it used AI to choose the profile? I mean, those flower tendrils resemble some pretty sexy tentacles. 🥰

I don't know whether Affinity Photo V2's ICC Profile box assigns the profile, performs a conversion, or something else. Reopening the exported file produced "The Embedded ICC Profile cannot be used because of a program error. Ignoring the profile." pop-up in Photoshop CS6 for me. Although the image wasn't corrupt, the profile is. I couldn't replicate it.

So... Um... I guess that makes two bugs...?

One possible fix for you is to make sure you explicitly set the ICC Profile box in export settings.

Disclaimer: I'm somewhat colorblind but this preview looks OK to me, even though the resulting file choked Photoshop:

(CTRL+Mouse Wheel zooms the preview window. Zoom all the way out and then back in you can get 101%. Not exactly 100%, but good enough -- A phrase evidently uttered frequently during the development of V2.)

Thank you but it doesn't help.  The box at the bottom for an ICC profile just inserts a profile into the image which tells other programs what the profile is.  It will have no effect on the way the image saves.  Besides which the image displayed as a preview is wrong so none of those settings have any effect until you actually save the image.  The problem is all within Affinity Photo 2.

It'll convert the exported file to use whatever colorspace / ICC profile you select in the export dialog. If you're not exporting in sRGB, then you need to click the checkbox to embed the profile, otherwise there'll be an assumption it's sRGB and if it's not, then it will display incorrectly.

But if you're exporting as sRGB, even if you're not embedding the ICC profile, it should display correctly. So the question arises whether you're sure you're actually working in the sRGB colour space or not.

I also could not duplicate this problem.

Thank rvst but the issue occurs before exporting the image.

I have found the issue.  In Preferences there is an option to keep the original colour space which by default is not checked - how crazy can you get!  Checking that and all works fine.  It appears that Photo 2 uses some undefined colour space if you don't check it.

I only see a box to convert colorspace, which is unchecked in mine, although I'm not certain that's the default.

I do know when loading a Nikon RAW file, if it will ignore whether it was shot with sRGB or AdobeRGB.

That's the default and it is the issue.  It makes no sense to just ignore the document colour space and assume it is the same as the working colour space.

I think RAW files ignore colour space as it is just the data from the sensor.  The software massages the raw data inot a colour space.

I don't see a Keep Color Space, just Convert. What am I missing?

 

Nikon cameras name RAW files shot in AdobeRGB as "_NKN1234.nef", whereas sRGB are saved as "NKN_1234.nef". The colorspace is noted in the RAW, as Photoshop and others will honor it, but I'm not entirely clear on the implications.

Convert opened files to working spcae box.  You have the option it seems of just converting or warning if ????   By default neither is checked and that is where I had the problem.  Setting it like you have fixes the issue. 

So try and see what happens if you uncheck both boxes.  Olympus does the same with file names.  I can't see the point but I only shoot jpg as I couldn't see any advantage to shooting raw after trying it a few times.
