Thanks Lea, I do not think that's the problem but will keep that in mind. I now have a reasonable result, but no one way to get it right. Every picture is a trial and error proces to get it right. If I ever come to a proper solution of the problem I will share it here. Cheers! Femke

Thanks again! I will look at it tomorrow (filesize stays the same after uploading is the one thing I quickly checked for now). I'm a bit lost at this moment. Just look in inspector what size the picture is showed and upload the picture in that same size seems very logical to me, but only works sometimes. I really do not have a clue why sometimes it works fine and other times the quality is really bad. But I'm so lost that I don't even know what my question would be, so I call it a day.

Hi Timo, Thank you for thinking with me! I discovered something stupid that might be the problem. I compared the original affinity file with the exported jpeg but the jpeg file I opened with the regular software from my pc instead of in Affinity. The jpeg opened outside Affinity lost a lot of sharpness. When I open it in Affinity too the quality is ok. How come it has such a bad quality when I open it outside Affinity? When I share my pictures with people they will not open it in Affinity. I'm insecure of what quality they receive. I can't upload my zipfiles. About losing sharpness when uploading for my website, I'm still looking for the answer. But I think maybe I still keep the pictures to big, I am now trying to look up in inspector what size I should best use. Cheers! Femke

Hi, I have this picture which is not that sharp and since I want that picture on my website and there it's always turns out less sharp, I used high pass filters to make the picture extra sharp. But when I flatten this image (couple of high pass layers) then the flattened picture is less sharp than the picture with the layers (before flattening). The same thing happens when I export the picture (without first flattening and quality100%) to a jpeg file. I use the most sharp resample Lanzarote 3 non- separable. But still I lose a lot of sharpness. Can anybody tell me what I'm doing wrong? Are there ways (besides taking better pictures in the first place ) to keep the sharpness in sharpened pictures in jpegs for the web? And also tips and tricks for what's the best way to get sharp pictures on your website are more than welcome because that's a big struggle for me. Thanks for taking the time to think with me, Femke

Thank you MEB for thinking with me, that's very good to know. When I start working on a photo I will temporary save it to my internal drive and only write it back to my external drive when I'm finished.

I was in a hurry , so started editing the original file all over. So I'm fine now for that particular picture. Still curious however how a file can be corrupted. Maybe I'm doing something wrong. Thanks Femke

Same problem here, but my photo is on an extern USB harddisk. Is there anyway that I can open it or restore it? I was working on it all morning (kept it open) and now I closed it, I can't open it anymore. Please help me. I need that picture. Femke

Thank you so much again Wosven for making it simple again, it was getting awfully complicated in my head. The one thing that still is a bit confusing in my head sometimes is the difference between actual DPI and effective DPI. I looked it up and found a useful explanation I will share beneath for members who also have difficulties grasping that part. As I understand it now, the dpi you fill in with scaling doesn't matter at all. It all depends on the dpi of the original file and the effective dpi you get after enlarging or reducing the image. That's the DPI Affinity calculates for you when you enlarge or reduce the image without resampling. (And the other way around, if you fill in a DPI of 152 without resampling you see the maximum measures of the picture to get a good quality print.) Many thanks Wosven! Here's the article: PREPRESS TWO CENTS: Actual Resolution vs. Effective Resolution Understanding the Difference without Using the Nasty Math OR: My Photos are all 300 dpi; why do some look so bad? In a perfect world, we would always scan our photos or take our photos at 300 dpi and use our photos at 100%. In the real world, though, we’re often forced to scale our photos once we put them into our page layout program. And that’s where the problems start. Let’s say you placed a 300 dpi photo at 100% (see Figure A). Now the customer wants the photo twice as big, so you enlarge it to 200% in your page layout program. The actual resolution of this photo is 300 dpi, but now that you’ve scaled it, the effective resolution is 150 dpi, or half the original resolution (see Figure B). Why? Once you enlarged the photo, all the pixels became twice as wide and twice as tall, so now fewer of them will fit “per inch.” Conversely, if you reduce your photo, the pixels become smaller and more of them will fit “per inch.” (By the way, don’t email us complaining that there are 9 dots in Figure B instead of 8-and-a-half; we’re just making a point.) In a nutshell: reducing the scale increases the effective resolution; enlarging the scale reduces the effective resolution. I know we promised no math, but for those of you who don’t mind it, there’s a simple formula for calculating your effective resolution. Take your native resolution and divide it by the scaling percentage like this: 300 ÷ 200% = 150 (dpi) or 300 ÷ 50% = 600 (dpi)

Hmm I'm afraid it's not all clear to me though. These formats are digital prints I offer to customers for printing purposes. I want this files to be print ready, in the sense that customers do not have to make any adjustments. When they print this file (at home or at that local printservice) it will be in the correct size in good quality. With the size 3509 x 5264 I can make prints in optimal quality up to 29,7 x 44,6 cm (pixels:118) so lets say 30 x 45 cm. But since you see larger images from a bigger distance you do not see see all the pixels and you do not need 300 dpi resolution to have a good quality image I thought. So for the 40x60, 50x75, 60x90 cm prints I thought that a dpi of 222,178, and 148 is sufficient (doubting about the 60x90). (See table in Dutch but the first column is format, then viewing distance and then minimal resolution for a good print, size and megapixels). So what I think to understand is that the 20 x 30 and 30 x 45 cm images I make a 2360x3540 pixel and 3540 x 5310 pixels image and it does not matter which resolution I put it on. (But I will put it on 300 dpi). These pixeldimensions correspondents with the size. But how do I make these 40x60, 50x75 and 60x90 cm print ready? Do I keep the 3540 x 5310 pixels and fill in these lower dpi's? Will it than automatically be printed in the correct sizes? Or will it print at 30x45 cm since the printer only looks at the pixeldimensions? I think because it's print the resolution is important and not imaginary isn't it? And is setting a lower resolution preferable above resampling the image to bigger pixeldimensions?

Hi Wosven, Thank you so much for taking the time to explain it to me so clearly! Only look at the pixels in width en depth and dpi is not important, imaginary value. That makes life a lot easier I think . I will go and try it out tonight. You really make my day!!! Thanks!

Hi, I'm reading this post and don't understand everything but I think I may have the same question. I have a picture in 2:3 format that I know how to change in size without resampling in Affinity. Affinity calculates the right dpi for me. My problem is that I like this picture in a couple of different ratio's (ISO, ,3x4, 11x14, 4x5) and each ratio in different sizes but I do not want to resample. So I need to crop. But when doing that Affinity automatically sets dpi to 300 or I have to calculate and fill it in myself. But since they are different ratio's I do not know the dpi I need for no resampling. I have to do this for a lot of pictures (selling prints in different ratio's and sizes) so I'm looking for a simple way to change ratio and size without resampling. So that affinity is calculating the right dpi for me. Using presets would be helpfull. But when I use a preset of ISO A3 for instance it's also resampling. Maybe there's another way for me to set presets with the right dpi's. Does anyone know how to calculate this when changing from ratio? Then I calculate this for all ratio's and sizes for one time and make presets for all the other pictures I like to change in ratio and size in the future. Or is resampling not so bad as I think and should I go for the easy way and use resample? I'm using sizes form 20x30 cm up to 60 x 90 cm ( 21x29,7 up to 59,4 x 84,1, etc). I know I will have lower dpi's than 300 for the larger images but it should be fine with the viewing distance. The original file is 3509 x 5264 pixels at 300 dpi. Please keep the answers simple since this is higher math for me 🙂 ps I know that not every picture is suitable for all ratio's. But this one is.

Thank you for thinking with me! I changed the preferences. But I'm afraid the problem was on my side. It's a photo I edited years ago and since I don't have Photoshop anymore I couldn't see which copies had layers. I think I just tried the wrong copies and found an older copy now which has layers. So I can work from there. No idea of it's possible because of the changed preferences or just finally picking the right copy. Any ways I should make a better administration Thank you so much for responding! I'm very happy to be able to continue.

Hi, I'm new in using Affinity Photo (loving it!) and I hope you guys can help me out with something. I like to adjust a psd multiple layer file that I made in Photoshop. But when I open the file in Affinity Photo it's a flattened picture, no layers. When I search for it on internet I see people opening psd files with affinity and the layers are automatically there. What could be the problem? I't's just this one psd file that I really would like to have in layers in Affinity Photo, so if there are ways to work around it for this one time I would be very pleased. Thanks! Femke
