From every wedding I sort my images in bridge according to these ratings:
1) Out of focus, massively bad exposure (not too many of these luckily), and really boring photos. Lighting tests.
2) Duplicates, boring shots
3) Proofs
4) My picks for the album
5) Portfolio shots
Everyone in #1 gets deleted, everything else is current kept as RAW, backed up, etc. I just added up everything classed as #2, it comes to 28GB just for the past 12 months!
I can't bring myself to ditch them all, in case great aunt mildred dies and they want me to see if I have any images... but then again they've never seen them and probably wouldn't think to ask. I think i'll manually look them over, delete the really bad ones, and archive the rest as JPG - a space saving of around 80% or so, which is significant given i've enough space on my drives for about one more wedding before I have to buy more storage (this is a business remember, every $ counts).
What does everyone else do with these #2 type shots?

... we file group 2 (and group 1) onto DVD and keep them - we never knowingly delete anything we bring back from the day. Past experience in life has taught me I always need something the day after I threw it away.
