Downsizing Issues

I've tried several things and continue to get poor results downsizing imported layers. Initially I brought in a folder of layers that had a mask on the folder and sized it down to match the size needed, but getting very low quality results. Very jagged. I tried applying the mask, flattening the folder's layers, bringing layers in as a smart object...everything gives me the same results. I've changed the image interpolation settings and tried it all again. If I resize the folder of layers using Image Size in its initial document, then drag that folder over, it looks fine. The attached image is the results from pre-sized vs. transformed after import (400% zoom).

I've uninstalled and reinstalled. This just started happening a couple days ago. The only significant thing that I can relate to the time was that I uninstalled Photoshop Beta about that same time. 

Photoshop 25.0.0
macOS Sonoma 14.0

Either the numbers typed are wrong, or you are distorting your image. On my end, the mentioned downsampling works just fine.


Yes, I typed 1887 but meant to type 1168. But the size I transform down to make no difference with the results I was getting. I was not distorting the ratio at all. I do not work with small dimension files. 400% does not fit my screen. 100% doesn't come close to fitting on my screen. I simply sent a screen shot of a problematic area and a shot of what all was showing at 100%. These are large files with plenty of quality. This was not a resolution issue and it was not a mishap of distortion. I'm 25 years into Photoshop. This was an anomoly that made no sense. Restart, reinstall, nothing changed it. And guess what. It just stopped happening, with no reason why. I've had PS open this entire time trying some of the suggestions from the forumn. And now suddenly it's all working properly. I didn't do anything to try to fix it and did the task the same way as several times before. Now it displayes as exepcted. Anyone know if Photoshop has a medical issue?

Zoom level is problem, take a look at 100% zoom, nobody will look at the image at 400% magnification.

    I showed it at 400% to highlight the issue. It does not show well at 100% either. Regardless, the two samples should basically be the same, even at 400%. Attached is shot at 100%.

    Not exactly, especially when you work with small dimension files. They will never be the same, not even close. Photoshop generates previews for speed rather than quality. If you enlarge a small dimension file by 400%, it will always look awful. I think you probably work with small dimension files because 400% magnification fits your screen.

     

    Can you provide more information, such as the starting dimensions and the amount of downsampling and magnification involved when assessing the quality of the downsampled image?

      What are the pixel dimensions of the original vs. the resizing?

        Original is 2023 x 3110 @240 DPI.
        Resized is 760 x 1887 @240 DPI, but it doesn't matter what I size it down to, the results are the same.

          Could you please post screenshots taken at View > 100% with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible?
