sbernard Posted June 11, 2019 Share Posted June 11, 2019 Hello, I noticed a problem with Affinity Photo, version 1.7. When I develop a photo in RAW, it is very dark. This problem was not present with version 1.65. Can you help me ? Thank you With Affinity Photo 1.7.0.367 version Under Lightroom Thanks for your help. Stéphane.

Mark Ingram Posted June 12, 2019 Share Posted June 12, 2019 Did you develop to 32-Bit? Is "Enable HDR" available in the 32-Bit Preview panel? Quote Link to comment Share on other sites More sharing options...
sbernard Posted June 12, 2019 Author Share Posted June 12, 2019 I don't develop to 32-bit Quote Link to comment Share on other sites More sharing options...
sbernard Posted June 12, 2019 Author Share Posted June 12, 2019 (edited) In the "info" part, there is the mention "RVBA/32 (HDR)" Edited June 12, 2019 by sbernard Quote Link to comment Share on other sites More sharing options...
AiDon Posted June 13, 2019 Share Posted June 13, 2019 Try turning on the tone curve in the develop assistant a it is a Linear RAW conversion.

sbernard Posted June 13, 2019 Author Share Posted June 13, 2019 Thanks AiDOn for the information. It is actually less dark, but the picture is still too dark. And that's not normal. Quote Link to comment Share on other sites More sharing options...
sbernard Posted June 13, 2019 Author Share Posted June 13, 2019 To add an additional observation, we see a difference between the photo displayed in the workspace and the thumbnail photo in the navigation tab. It's not normal. Quote Link to comment Share on other sites More sharing options...
Mark Ingram Posted June 13, 2019 Share Posted June 13, 2019 What colour profile is your monitor set to? And what colour profile is the image in? PaulAffinity 1 Quote Link to comment Share on other sites More sharing options...
sbernard Posted June 16, 2019 Author Share Posted June 16, 2019 Hello, For my monitor, the color profile comes from the calibration of my screen, namely color temperature at 6000K, brightness 100cd / m2, gamut at 2.2. For the photo, it's a raw photo, NEF format (Nikon) and Nikon_RVB standard color profile. Thanks, Stéphane. Quote Link to comment Share on other sites More sharing options...
phil750 Posted June 18, 2019 Share Posted June 18, 2019 Just to add i am getting the exact same issue, no issue with importing files in 1.6, opened a file in 1.7 and its way underexposed. in Fastone viewer it looks fine, i would say in affinity its almost 2 stops down on what it should be. Add exposure just doesnt look right either. Tone curve makes it darker, changing from 32 bit to 16 bit also makes it darker. Quote Link to comment Share on other sites More sharing options...
Mark Ingram Posted June 19, 2019 Share Posted June 19, 2019 If you set Develop Assistant options to 16-bit, then press 'Develop', does the image get brighter? Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted June 19, 2019 Staff Share Posted June 19, 2019 Hey @sbernard and @phil750, Would you mind dumping some images into this private Dropbox folder - https://www.dropbox.com/request/z6ARWntXqq3GyeStJiPW We suspect it may not be image related but it's worth testing it our end with the same images you are using.

sbernard Posted June 19, 2019 Author Share Posted June 19, 2019 Hello @Chris B and @phil750, I tried several times to file a file with the dropbox link, but impossible, processing error. Otherwise, I opened a photo that was a problem, but that's ok. The picture don't appear dark. During the anomaly, my affinity photo version was in 1.7.0.367. And now, I am in 1.7.1.404. The bug has been fixed? Thank you Stephane. Chris B 1 Quote Link to comment Share on other sites More sharing options...
phil750 Posted June 20, 2019 Share Posted June 20, 2019 Hi i uploaded a file i had previously edited in 1.6 and it worked fine to the dropbox, this file in 1.7 also goes underexposed. So pretty sure its not a file problem but no harm in uploading for you to try. I am also on 1.7.1.404 and it still does it to me but strangely only on 1 monitor. If i print screen the image, it goes back to looking fine on the same monitor! It also displays fine in the preview in the bottom right but underexposed in the main picture. I am shooting with a nikon d500 if that makes any difference. i did find a workaround which is in 32 bit preview, enable HDR mode - and add 1.6-1.8 stops of exposure to get back to where it should be.

Mark Ingram Posted June 20, 2019 Share Posted June 20, 2019 @phil750, do you have a HDR capable monitor? Quote Link to comment Share on other sites More sharing options...
phil750 Posted June 20, 2019 Share Posted June 20, 2019 Yes only 8bit though, i did try to turn it off but made no affect. Its strange how in affinity on the same monitor the main picture is dull but the preview is bright. also updated my gpu drivers just in case and made no difference Quote Link to comment Share on other sites More sharing options...
phil750 Posted June 20, 2019 Share Posted June 20, 2019 Ok found it, if i turn off HDR in windows displays settings solves it. Turn it off in the monitor no difference. Quote Link to comment Share on other sites More sharing options...

Unfortunately, due to the way Microsoft implemented HDR in Windows, they have 2 different concepts of brightness - 1 for SDR, and 1 for HDR. The SDR brightness can be changed in the HDR Settings dialog, but the HDR brightness cannot be changed (although some monitors do allow you to change the reference white level). This means that HDR and SDR content on the same screen can appear at different brightness levels, which is incredibly confusing. When we implemented the feature, recognised this could be an issue for users, but we decided to "wait and see" what the reaction of the customers was first. There is a potential fix we could apply here, which would involve scaling the brightness of any image on a HDR capable monitor by the SDR brightness level in Windows, when the "Enable HDR" checkbox is disabled, but this leads to a change in brightness when toggling between the "Enable HDR" state (which would also be confusing).

Turn it off in the monitor no difference. You probably want to keep HDR on (read my post above for an explanation). Out of interest, what is the make and model of your monitor?

phil750 Posted June 20, 2019 Share Posted June 20, 2019 thanks for the explanation. I will have a play around with my monitor and see if i can get the settings working, if not its not a massive hassle to turn HDR on/off when im editing as i tend to do it all in big batches. im currently using a AOC Agon AG322QC4 , so a gaming monitor more than a photo editing one, though does surprisingly well once calibrated properly.

Ah, OK, this is a HDR400 certified monitor (which means it's certified for 400 nits peak luminance). You should definitely enable the HDR ability within (Windows and) Affinity Photo - you will see a lot bigger range of brightness than before!

ch22 Posted June 21, 2019 Share Posted June 21, 2019 Actually, since a RAW file does not contain any ICC profile, the luminosity and the colors of a RAW file just opened does not matter very much. It's only at the output of the raw software that a ICC profile is added to the file and that RVB components are given a true color meaning. However, the camera JPEG file or the display by the system commodities or Adobe software (and many others, of course) are in reasonable agreement and thus offer a convenient reference with which Affinity Photo should comply — and unfortunately it does not always. Under MacOS and with Serif RAW engine, I observed nothing special with NEF, CR2 or ORF files, but I actually got this odd darkening with RAF files. However, it disappeared when I switched to the Apple RAW engine. Below are compared screen copies for RAF and CR2 between AP 1.6, AP 1.7 and Photoshop (in this case, with no correction) and a screen copy with the Apple RAW engine : Quote Link to comment Share on other sites More sharing options...

I too have very dark raw files (.orf in my case but also with other format) ever since the 1.7 update. Very disappointing too read it was known their was a potential issue, i did not want to complain and seeing plenty of others users talk about colors issues and files being to dark i assumed their was a fix in the works, instead i read this was by design..... i don't even know what bloody "feature" caused all this crap, why the heck is AF even loading my non hdr shots in 32 bits,iam lost for words really.....

I assume you have a HDR monitor then? I'm going to make a change in the next version that will only enable the HDR capabilities if explicitly enabled by the user (currently the HDR capabilities of the monitor, and the "issue" with Windows I described will be activated for any 32-bit images).

BorderlessCaptures Posted July 12, 2019 Share Posted July 12, 2019 My monitor is not HDR, i am not really sure how to troubleshoot this problem all i know is that it looks dark in raw mode (but not in the nav/preview) and i have to up the gamma in 32bit preview window to get them to match, but even then everything color/exposure related seems a bit off, maybe its physiological but i have not been able to get a result i am happy with ever since 1.7 Quote Link to comment Share on other sites More sharing options...
