Have to admit I’m quite brutal when it comes to culling photos. Back of the camera on location or back in the car is where it all starts. I don’t shoot loads of variations anyway, so only have a relatively small number to work through. The initial cull probably sees half the images deleted out the camera and not make it home. I’ll then Lock any images I like, just in case.. Then upload to LR, view full screen and cull any that don’t stand out to me. Probably leaves me with 3 or 4, maybe 5 images to process. I’m only shooting landscapes though.
