Great post - especially about talking to them and asking for their permission. I hear and sense them myself so whenever I go in to photograph, I always say hi and ask if they wouldn't mind letting me take some photos of them. Plus once they realize I can hear them, the gossip channels are open and everyone starts talking lol! I have some nice pics from Bachelor's Grove. One with a lady in blue with a little girl in pink, one with a hooded skeletal figure holding a baby and a few more fun pics. They've always been very accomodating for me. Just a bit chatty but then again the most chatty ones are in the older cemetaries in England.
