Ive never done anything in a church and I asked him about flash etc. he doesnt mind the flash. I said id keep the shooting to a minimum as to not intrude but he said take as many as you like.
I’ve done a few christenings now and they all went off without a hitch
I just popped down to the chapel the day before and said to the priest
Most Priests are grand but you can get an odd fuddy duddy
Best of luck and enjoy it
