I do mostly bird and wildlife photography. If I have a good outing with close approaches by multiple animals, I can come home with 600+ photos.
When reviewing the photos in Lightroom Classic (LrC), my goal is to find the 1 out of 100 that are my absolute favorites. Suppose for example that I made 200 photos during fly-bys of hawks. Not every fly-by is the same. If there's one during which the bird came so close that I had difficulty keeping the bird within the frame, I'll focus attention on thay set of photos.
Within each set from an encounter, I look for four things. First and foremost, I'm looking at the light on the bird. If the bird isn't well-lit, it's not worth my time to process the image and I move on.
I'm also looking initially at composition to confirm the subject is entirely within the frame. There are rare exceptions I'll make during particularly close encounters when the bird is well placed with good lead room but the wings are outstretched enough that one or both leave the frame. However, most birds - even when making a close passage - aren't that near. Keeping them in the frame usually isn't the problem.
Among the photos of a well-lit, nicely-composed subject, I'll zoom to a 100% view and check for tack focus on the eye and face, if focus is slightly off, the photo doesn't get marked for processing. If it passes muster for focus, the photo gets a 5-star rating.
The fourth and final criteria includes the "decisive moment" factors. Of the ten photos that have earned the 5-star rating, is there one in which the body and wing position is most to my liking? One in which the background is more pleasing? One in which there's a catch light in the bird's eye? One in which the bird is making eye contact with me through the lens?
The few photos that share those qualities get flagged as picks.
I've set up LrC to automatically add photos with 5-star ratings to a smart collection called, "Ready for Post". When I go into that collection, I'll often start by filtering to display only those photos I've flagged as picks. Amongst those, I'll mentally filter based on my tastes and prerogatives for the one or two photos out of 5 from that one encounter that are my favorites.
Those are the photos that get processed. In this way and through this approach, I can get through a 600-800 image outing in a single day and end up with 8-12 photos that get processed and added either to my portfolio or a favorites collection.
The other photos are still in the folder for that morning's or afternoon's outing. But it's the small number that stand out that get the full treatment. Depending on the keywords I've assigned, the star rating, color label, and flag status, LrC will automatically sort the processed photos into various smart collections, from those photos that were good enough to process to those that stand out as my best-of-the-best.
It's a process that serves me and my needs. It's helped me to keep a 160K image catalog manageable. It's an aporoach that can be adapted to any genre of photography. Set the criteria needed for an image to pass your muster and progress through your evaluation process until it ends up in a collection of favorites worthy of your time in LrC or your image processing & editing app of choice.
Good luck to you.
