Canvas Posted September 26, 2018 Share Posted September 26, 2018 Hi :) Whenever I open one of my pictures with AP it gets blurrier than the original. I especially see it when zooming in. The difference is not that huge but still a problem for me, as I need sharp pictures of my artworks. The screenshots show the difference. Does anybody know what the problem could be? Thanks in advance! Quote Link to comment Share on other sites More sharing options...

Staff Gabe Posted September 26, 2018 Staff Share Posted September 26, 2018 I can't see any difference between Affinity Photo and other apps. What App did you use to preview it? Some preview apps will smooth or sharpen the photo. Quote Link to comment Share on other sites More sharing options...
Canvas Posted September 26, 2018 Author Share Posted September 26, 2018 @GabrielM I simply used "Preview" from my mac. Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted September 27, 2018 Staff Share Posted September 27, 2018 Preview is pretty bad at colour management. A good example to show this would be to take a screenshot of your photo while opened in Preview, and open the screenshot next to your picture. You will see that the screenshot looks different. A quick test I've done. I actually took it a step further and took a second screenshot of the first screenshot. From left to right, you have the original photo, screenshot of the original screenshot of the screenshot. Quote Link to comment Share on other sites More sharing options...
Canvas Posted September 27, 2018 Author Share Posted September 27, 2018 @GabrielM Hm...but it actually even looks worse if I open the original in AP. If I open the image in Preview it is at least as sharp as in the original however if I open it with AP it gets very unsharp. This is what I tried to show with the first two screenshots. The upper one is opened in Preview whereas the lower one is opened in AP. Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted September 27, 2018 Staff Share Posted September 27, 2018 I've checked our app preview against 2 different apps (Photoshop and the basic Paint) and they all show the same "blurred" image. I believe the Preview might add some sort of sharpness to the image. Quote Link to comment Share on other sites More sharing options...
Canvas Posted September 27, 2018 Author Share Posted September 27, 2018 @GabrielM Okey, thank you. Then I'll have to find a way to take sharper pictures in the first place. Quote Link to comment Share on other sites More sharing options...

Thanks for your answers. But does Preview sharpen it now or not? Quote Link to comment Share on other sites More sharing options...
PopstarNZ Posted October 15, 2020 Share Posted October 15, 2020 (edited) I'm not convinced the feedback given in regards to this question is right. I just did a quick experiment where I used Graphic Converter top open and convert my NEF file to Tiff (to prevent any compression issues) and open that into Affinity Design Vs Open the NEF and develop in Affinity Design. The second path had loss in sharpness. There is something in the way the Affinity Design is opening the file If someone could find a fix for this I would be grateful.

Staff Gabe Posted October 15, 2020 Staff Share Posted October 15, 2020 Hi @PopstarNZ, Welcome to the forums. When you converted your NEF to TIFF, that software "developed"/processed the file. If it was a 1 click process, it most likely will noise reduct/sharpen your image, more like an in-camera processing when shooting jpeg. We don't add any sharpness to the developing process, as this can be controlled by the user in Develop Persona. Quote Link to comment Share on other sites More sharing options...
lepr Posted October 18, 2020 Share Posted October 18, 2020 There is something very strange about PopstarNZ's screenshot. The px rulers of each document window are being displayed at equal scale, but the title bars of the windows say the view scale for the NEF is twice the view scale for the TIFF. The NEF is being displayed by one screen pixel per view pixel, whereas the TIFF is being displayed by four screen pixels per view pixel. In other words, the 25.3% view of the TIFF is being "pixel doubled" for display. Does anybody know why the TIFF is being displayed that way?

Old Bruce Posted October 18, 2020 Share Posted October 18, 2020 @anon2 I would think the different view's zoom level is down to different DPI/PPI in the two photos. This may also be part of the difference in perceived quality. Quote Mac Pro (Late 2013) Mac OS 12.7.4 Affinity Designer 2.4.1 | Affinity Photo 2.4.1 | Affinity Publisher 2.4.1 | Beta versions as they appear. I have never mastered color management, period, so I cannot help with that. Link to comment Share on other sites More sharing options...

AlainP Posted October 18, 2020 Share Posted October 18, 2020 @anon2, you're right about his post. On one of the images he posted the zoom is twice as much so the resolution of the picture has to be twice as low, so it get "pixellated" once zoomed. This seems to be a bias comparaison (maybe not intended) by @PopstarNZ who has only one post on this forum.

That doesn't explain the "pixel doubling" when zoomed out to 25.3%. "Pixel doubling" is expected when zoomed in to 200%. Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted October 23, 2020 Staff Share Posted October 23, 2020 That's an interesting finding @anon2 . I can't replicate it here from scratch though. Perhaps @PopstarNZ can attach the original files? Quote Link to comment Share on other sites More sharing options...
