I can hear it now, "move that branch a little to the left, no your other left"! Beautiful shots! I don't envy you sifting through to find the keepers, but it looks like it's well worth while.
It's really not al that tough to go through the shots.
I use Photoshop CC with Bridge.
In Bridge, I enlarge the photo to 200% and check to see if it is sharp, if it isn't, it's deleted.
I normally toss 20% of the photos in this faze.
Then I look for shots that have poor poses, or are just off putting to my eye. There goes another 20%.
Then I start looking for the ones that I think jump off the screen, or at least they do for me on that day.
When I find one, I process it.
On this day, I kept about 400 shots, processed 13, and in a couple of weeks I'll go through them again to see if anything else appeals to me.
After that, they go to the back up drive and will probably sit there til I'm dead.
All in all, this process only takes a couple of hours with this amount of shots.
Because all the shots are in the same place, with the same lighting, I just copy the settings, and in ACR, use the same settings on each shot.
There may some minor adjustments, but they happen quickly.
Then into Photoshop, resize, and save. Of course there are times that I'll spend a half an hour on a shot, but that's pretty rare.
