![]() ![]() If the adobe apps didn't work this way, then technically they would be deceiving the person working on the image by making them think that what they were seeing at 200% was actually the 100% view. Certainly when I look at an image in LR at 1:1, it is not as "blown up" as it is in preview when I click view "actual size". I might be mistaken, but I think LR works this way as well. Don't forget, the native res of the 27" iMac means that if you open an image that is 5000px long (so around 20MP?) and go fullscreen, you don't even have to zoom the image as it is already technically being viewed at full size 100%. So in this sense PS is working correctly. It took me a while to work out why virtually no image I look at fully zoomed actually looks pin sharp, because it is in fact being blown up to 200%. It's also worth noting though, and I guess you may already know this, that the way most applications are behaving in the pixel doubled res isn't actually showing you images at 100% when you view them in "actual size" but at 200%. I noticed this pretty soon after starting to use PS that I was having to zoom up to 200% to see the same size output that I'd see for instance in the preview app had I clicked the option in the view menu "actual size". My guess is that PS is trying to be smart because most people will run in the default resolution on Apple's retina displays which is pixel doubled 2,560 x 1,440 (otherwise, if you ran at native res everything would be so small you couldn't read it) and so even in this default "pixel doubled" res PS is attempting to display everything as if you were running at the native res. ![]() I think I understand what you mean, and I have noticed this as well. The only way around it is to start PS in "low res mode", but that makes things "fuzzy". ![]() Whatever setting I choose, the image is 1/2 the size (linear dims) it should be. So I changed the setting and proved the PS is taking this setting into account. The 1,000 x 1,000 image I see on screen is only 11.5cm across on a screen that is 59.5cm wide.ġ1.5/59.5 x 2,560 = approx 500 pixels (instead of 1,000)Īt first I thought this must be because the true display resolution of the 27" iMac is 5,180 x 2,880 and PS is simply not respecting the scaling set in Apple System Display settings. Measure the width of the image in cm when viewed in the PS edit window at 100% Open Photoshop in normal mode (not low res) and create a 1,000 x 1,000 image Set the Display resolution in Apple System settings to 2,560 x 1,440 (the default) Is there anyone here with a 27" iMac with a retina display who can try a simple test? I'm trying to find out if it's just me (due to a setting gone wrong somewhere during the migration process) or if there's a bug. I expected images in PS to appear about 1/2 size (linear dimensions) on the iMac than they did on my previous non-retina system, because the pixels are half as big. But I'm seeing images that are 1/4 of the size. I'm running Mojave and the latest PS CC (21.2) on a 27" iMac with Retina Display. ![]()
