@HughWRoberts Weddings have absolutely changed in many ways
Weddings back then (especially this great pic that you shared) weren't so publicly documented and it was more private compared to today.
Now a days weddings are much like a major events and a very big business photography-wise that kind of started around the late 2000s and the 2010s in particular. If you're in a wedding today, it's certain that it's going to be public somewhere and every photo is documented.
