Thanks, Kirk. Just to explain my way of working: I wanted to delete certain images from the contact sheet before ingesting because they were definitively undesirable, and I didn't want to have images on my drives that I wasn't even going to process through a raw coverter. So, to me, deleting is useful at the point where I am seeing what's on my card, and before I copy them to disk. Maybe, being new and not really up on thing, I am missing some other convenient way to omit a frame or two from the ingest.
