Yearbook staff using flashes during SV game

[Rookie]

I was working a girls sub-varsity game the other night, and I did notice the yearbook staff taking some pictures, with a flash. During halftime a player from the visiting team asked me if I could prevent the use of the flash it was distracting them. To make a long story short I asked the girls to take as many pictures as they like, but please don't use the flash. (caught a little grief from somebody that worked at the school)

As I was driving home, I was thinking, if it was a parent using a camera flash, would I have asked them to stop?

Did I do the wrong thing here?
