I have no clue really on my end which photos are good or not. There are certain dance poses that only they would know if the leg or arms or whatever are in the correct position.
My initial thought was to share the album to them and have them "heart" the ones they like. I just did this with a test album with my wife. When I view that album in LR though, I'm not actually seeing a way to "filter by hearted" photos.
Am I missing something? What's the best way to have a client choose the photos they want edited?
I do see in LR that I can click on the little comment bubble tab and see if they put a heart on a photo that way. With this method, I'd need to flip through every photo and flag ones that they hearted. Time consuming but doable.
To clarify on my first reply - in Lr desktop, if you're in "All Photos", comment and heart icons don't display on thumbnails. You need to have the Shared Album selected - then you'll see the heart icons display in the lower-right corner of each thumbnail (much easier than clicking into each image).
The closest I can get to your goal is selecting all the heart'd photos in Lr and then moving them into a separate "Client Pics" album (or flag them, give them a star rating, etc.).
Liked photos are pretty easy to spot in Lr (desktop), since thumbnails display a white heart in the lower-right corner. I can't find a way to filter on this data either. Hope this is helpful in some way.
