On macOS Sequoia 15.2, when I have an image file selected in the Finder and press the spacebar to get a Quicklook preview, the image opens but then fades in over a second or two. I wish to disable this fade in and have the image displayed immediately at its full brightness. I tried enabling "Reduce motion" in the Accessibility settings, but that didn't help.
MacBook Pro 16″, macOS 15.2
I think I figured it out. It only happens on camera raw images from my OM Systems (formerly Olympus) image files. JPEGs, PNGs, and HEICs do not exhibit this behavior. I'm guessing that the fade in has something to do with the extra processing needed to handle the large amount of data (each image file is about 20 MB).
As for Sequoia 15.3, yes, I plan to update, but I usually wait a few weeks after each macOS update is announced to see if there are any problems. I haven't heard of any so far, so it's probably time.
Thanks for your replies.
I have never seen that behavior. Does it happen in safe mode or under a new dummy user?

If you hold the Shift key down this fade in is a feature... the genie effect.
Try making some changes to your settings and compare your results
View and edit files with Quick Look on Mac
if no resolve— look at your Keyboard Viewer and see if that Shift key is working correctly(?)
You can do a SafeBoot Start up your Mac in safe mode - Apple Support to sort anomalies
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
Can't say I've experienced what you describe with any of my Macs running Sequoia. Speaking of, you should update to Sequoia 15.3.
I want to stop the fade-in Quicklook does on photos
