user_0815 Posted July 24, 2023 Share Posted July 24, 2023 When using the HSV saturation slider, it generates colours that I would not expect to be there. Am I "holding it wrong" or is this a bug?

Dan C Posted July 25, 2023 Share Posted July 25, 2023 Hi @user_0815, Thanks for your report! I'd like to request a copy of your .afphoto file in order to investigate this further - can you please attach a copy of this here for me? If you'd like a private upload link for this file, please don't hesitate to ask Quote Link to comment Share on other sites More sharing options...
user_0815 Posted July 25, 2023 Author Share Posted July 25, 2023 See example file attached. It happens in any file that I edit. IMGP6863.afphoto Quote Link to comment Share on other sites More sharing options...
Dan C Posted July 25, 2023 Share Posted July 25, 2023 Thanks for providing a copy of this document for me - I can confirm I'm seeing the same behaviour, though this may be related to your Lens / RAW file specifically. I have downloaded a sample RAW file for the Pentax K-1 from Photography Blog, which is using a supported lens and the same issue does not occur - Do you have any RAW images from this camera that are using a supported lens? Do you see the same issue when opening this within Affinity? Quote Link to comment Share on other sites More sharing options...

However, it does happen in any kind of file. For example I've edited a screenshot of an image which shows the same behaviour. Please note that it only happens in HSV but not in HSL mode.

My sincerest apologies, I thought I had enabled this option in my testing but I can see from my screenshot that this is not the case - that is my mistake! 17 hours ago, Red Sands said: If I run it through Photoshop (Camera RAW) with and without corrections, I only see serious discolouration in that area when saturation is pushed to the max. And that's very normal. As above, Photoshop is using HSL adjustment values, which is the same behaviour shown within Affinity Photo when not enabling the aforementioned checkbox. 21 hours ago, user_0815 said: However, it does happen in any kind of file. For example I've edited a screenshot of an image which shows the same behaviour. I do agree that the HSV option within Affinity Photo appears to apply saturation in a very aggressive ramp across all images and therefore I will be logging this with our team to be investigated further.

user_0815 Posted September 17, 2023 Author Share Posted September 17, 2023 A short follow-up: The aggressive ramp does also apply when opening files that were previously edited in V1. Using V2, the image looks different, depending how much of the HSL adjustment was used. It doesn't need much to get the unwanted funky look. Here a screen capture how it impacts opening a file that was created with V1 and is now opened in V2. First is Photo V1 where I turn the HSL adjustment on/off. Then I open that file in V2 where the colours are "rather different". HSL V1 V2.mov Dan C 1 Quote Link to comment Share on other sites More sharing options...
Dan C Posted September 18, 2023 Share Posted September 18, 2023 Thanks for letting me know & for the recording provided - I'm updating the development log now to include this info Quote Link to comment Share on other sites More sharing options...
user_0815 Posted October 11, 2023 Author Share Posted October 11, 2023 I'd like to bring up another finding. By just Adding the HSL adjustment, there is a colour shift in red. No need to do anything else, just add the default HSL adjustment layer. As far as I am aware, this happens when a new 32-bit document is created. Converting to another color space fixes it somehow, for example from Adobe RGB to ROMM RGB. How to reproduce: 1. Create a new 32-bit document. 2. Add anything of red colour, for example a shape or brush stroke. 3. Add an HSL adjustment layer on top. When I create a 32-bit document form raw via the develop persona, the existing reds from the raw file ("Background" layer) aren't affected, only the ones that are added later. Setting the adjustment layer to "Invert contrast" at 50% opacity should make everything grey. But in this case it doesn't. That's why I think it might be a part of the current HSL funkyness. Please see the attached screen capture. Bildschirmaufnahme 2023-10-11 um 18.55.53.mov Quote Link to comment Share on other sites More sharing options...
Dan C Posted October 12, 2023 Share Posted October 12, 2023 Thanks for the screen recording & steps provided! Interestingly I'm unable to replicate this issue on Windows, as adding the HSL adjustment does not change the colour values in any document - however I'm seeing this same behaviour on macOS and this certainly isn't correct, so I'm logging this as a new issue with our team now. In further testing, on macOS I can only replicate this when selecting the Red Swatch from the 'Colours' Palette, if I select a Red Swatch from any other Palette, or manually input the colour values, this works as expected. This would also explain why changing the Colour Profile in use would resolve this issue, as this converts the colours in use for the object and stops using the fill from the Swatch. I don't quite understand how this only occurs with the Colour Palette, though I'm sure our dev team may have more insight here. I hope this helps Quote Link to comment Share on other sites More sharing options...
Hangman Posted October 12, 2023 Share Posted October 12, 2023 Hi @Dan C, Just some additional info which may or may not be helpful... This only affects Photo, everything works as expected in Designer, Publisher and the Photo Persona in both Designer and Publisher. It looks like a screen re-draw issue and affects all 32-bit profiles but only when the Hue value is set to 0 or 360, set it to 1 or 359 and the Red displays correctly, set it to 0 or 360 and zoom in and out and you see a mix of Red and Pink...

Dan C Posted October 12, 2023 Share Posted October 12, 2023 Thanks for the above Hangman, I concur that the Hue value seems to be the trigger so I'll update the development log with this now. Strangely however I'm not seeing the re-draw issue across the shape that's shown in your recording - the whole shape is coloured incorrectly for me, seemingly regardless of document/rectangle size, but I will note this with the team also Quote Link to comment Share on other sites More sharing options...
Hangman Posted October 12, 2023 Share Posted October 12, 2023 Hi @Dan C, It actually appears to be a Hardware Acceleration issue, disable Hardware Acceleration and the issue is no longer there...

user_0815 Posted December 1, 2023 Author Share Posted December 1, 2023 For anyone finding this as well, turning Hardware Acceleration off and turning it back on again might work. The app needs to be-started each time. It worked for me. Quote Link to comment Share on other sites More sharing options...
user_0815 Posted September 18 Author Share Posted September 18 Just as a follow-up, Turning hardware accelleration off and on doesn't work any more. At least the last few times. I always get these artefacts in HSV mode. Also trying different colour spaces (sRGB, Adobe, Profoto) or 8/16/32bit. Quote Link to comment Share on other sites More sharing options...
