According to a source at the wedding ... security guard and family friend Ron Howard (not that one) approached the photographer and asked him to leave.

Sources say Howard told cops the photog -- Robert Martinez -- put his forearm on Howard's throat -- and then yelled, "I'm packing a gun." That's when the fight really started ... and someone at the wedding called cops. Clearwater PD confirms a gun was mentioned during the altercation.

And there's this ... we're told Martinez's video camera was rolling during the fight -- and cops watched his tape when they arrived.

As TMZ first reported, no one was arrested ... however, we're told cops want to talk to Howard one more time about the incident.
