Yes, that is my procedure: 1. get home from shoot 2. Ingest (PM term for copy) all cards to designated folder on photos hard drive. I have three card readers with a total of 5 slots. PM will copy all slots simultaneously to the designated drive/folder. 3. Back up the new folder of new images to local file server, 4. Create PM"contact sheet"(looks similar to grid view in LR) 5. Preview images in PM. Preview is like loupe view in LR - full screen view 6. Scroll through images in Preview and Tag ("T" key short cut) those I want to bring into LR. 7. Filter PM contact sheet to show only those un-tagged images, 8. Quickly scroll through un-tagged images for any potentially missed good ones. 9. Select all un-tagged images and delete to Win 10 recycle bin, 10. Import tagged images to LR. 11. Take quick break while LR imports and creates previews and smart previews. 12. Use LR star ratings to narrow down number of images to process, The rest of my work flow is similar to yours, but I've never felt the need to rebuild previews, Note: I find that marking rejects in LR and then Picking for processing to be wasted effort. I just pick and go from there, Also, when I shoot in low concert lighting, I use the same ISO all images from all cameras so I can sharpen, set noise reduction and vibrance for one image, then sync those to the rest of the finished shots.
