Color label doesn't apply to multiple pictures in filmstrip when in Loupe View

[paytonfrost]

I use color labels to denote what pictures need future processing. Green photos need to be panorama merged, blue photos need to be stacked for astrophotography, yellow are HDR merged. When I'm culling from a shoot I'm in Loupe View most of the time using the flag system to denote edit/no-edit pictures. A lot of my shots are single pictures, but I come across sets of images that need to be marked with green/blue/yellow and then grouped.

When in Loupe View, if you select multiple images on the filmstrip and then hit "8" to mark them as green, only the first one in the selection set gets marked as green. However, when I switch to Grid View, hitting "8" does mark all selected photos as green. Interestingly, if I'm in Loupe View and I right click on a picture in a selection set and set the color label, that will mark all of them as that color label.

It appears it's something in the keyboard shortcut that doesn't allow this. Would appreciate clarification on if this is a feature not a bug. Current workaround is to switch to Grid View each time I need to group things, but that gets tedious when I'm working through a 10k image set (just got back from 5 months on trail, so so many panoramas and astrophotography sets to process).

Julianne Kost has a good video on this subject.  From that video:

"To apply metadata (or keywords, quick develop settings etc.) to multiple selected images when NOT in Grid view (for example when in Loupe, Compare, or Survey view), click the “light switch” next to Sync to enable Auto Sync. I find Auto Sync especially useful when using Survey mode. For example, lets say I start with 10 images and then remove the less important ones until I only have 4 left. If I want to flag, rate or label all four of those images at one time, without leaving Survey mode, I enable Auto Sync, apply the flag/rating/label and whatever I do to one, is done to all. Just don’t forget to flip off Auto Sync when you are finished."

Ahh, so it's a feature not a bug 😅 This helped!

I reported a similar bug that was ignored. If you have two windows and show the toolbar, applying a color label from the toolbar button won't apply it to all selec5ted images in the secondary window. But, right-click and apply and it works. Apparently this is not a bug. :sigh: Just stupid.
