If the couple were wandering for 5 hours then that will be what THEY wanted.We took wedding photographs for 50 years ,We planned with the couple ,in earlier times the mothers,how much time we had for photographs.
The best laid plans however can go wrong when Hotels/venues lead the B &G up to their room for afew minutes peace and they dont come back for 2 hours!
Of course the photographer gets it in the neck from all the guests .the caterers and the band because everything runs late,
Nothing to do with the photographer usually .
Digital changed photography ,when I started in 1969 it was all B/W with a dozen postcard size colour as an add on option .
When we closed the door due to covid SOME ,not all, photographers were of the quantity not quality type.We heard of weddings where they rattled off over 1000 shots in the hope of getting enough decent images
The old pro's called them machine gun types spray and pray.
There is no need for any qualified photographer who can control the situation to take longer than one and a half hours max and in fact we could cover a wedding in 45 minutes to an hour and get every shot needed/wanted
But then we were the generation who could get what was wanted on 5 rolls of 2 1/4 negatives b/w and one roll of 35mm. colour ,
That makes me feel old...
