photos with flash during playing action

[jodibuck]

In a NFHS game, as R1, I requested the local newspaper photographer to cease using a flash on his camera during playing action. He demanded to know what rule states that. I have been officiating volleyball for over 5 years, and this is the first time anyone has ever questioned this. When I began officiating volleyball, I was told that a flash was not allowed in high school volleyball.
