Photoshop Sky Replacement is Slow

[Jeff A. Goulden]

I am using Photoshop 25.0.0 and running Windows 11.  I'm using the Photoshop plugin from Lightroom Classic.  I'm having a problem selecting skies in the Sky Replacement feature.  I have my own collection of skies that I use.  There are around 500 of them to choose from.  What I am experiencing is scrolling through the pallet of skies is extremely slow.  When I scroll down it can take 5-10 seconds or more for the pallet to move.  It makes it very difficult to select the sky that I want to use.  The whole sky replacement feature is very slow compared to ON1 but selecting the skies is extremely slow.  Has anyone else experienced this and what can be done about it?

@Ben Glasgow I would use something like Image Processor to downsample and save out as jpg files to a source location.

Same issue here and it is so frustrating. Everything else works fine and fast. It seems to happen every time there is a software update. I end up deleting my skies and re-uploading them, but it is time wasting.

Take a look above at my Dec 20, 2023 post.  If you are uploading .psd sky files, and have a lot of them, it will be extremely slow to scroll through the sky pallet.  I switched my sky photos to .jpg and it works much faster.  I hope this helps.

Thanks for your reply Jeff. Mine are .jpg's and I have about 150 of them, most under 5MB and a few over but none over 10MB. The problem is not the end of the world for me as I delete the set and re-upload them if necessary after  Adobe software updates, but I wish I didn't have to do that.  My operating system has recently been updated to the latest and greatest to see if that would help, but the problem persists. It's just the scrolling between skies that is slow, once I selected a sky the actual replacement is fast.  I don't want to cull my skies as I edit at least 50 exterior real estate photos a day and cannot use the same ones over and over. While I'm at it, is there any way I can change the border colour indicating/highlighting the last sky selected from blue to another contrasting colour like red?

I have over 500 skies uploaded so I can't imagine what might be causing your slowdown, especially since they are .jpg files.  I don't know if you can change the border color of the last sky selected.  Someone more expert than I may be able to help you there.  You probably know that the last  or so skies selected are shown at the top of the pallette.
