Unfortunately the sports photography that I was exposed to was and is the very best basketball action pictures that I have ever seen. This was in the 1950s and consisted of a Monostrob slave at each end of the court aimed at the baskets. They were fired by an SR2 (100WS) electronic flash (strob) mounted on each of two 4x5 Graphic press cameras which the photographers aimed at the action. The pictures that I remember were made when the action was at one basket or the other. Needless to say, the two photographers did not shoot hundreds of pictures at each game but most of what they shot were usable. Everything was shot on 4x5 Super Pan Press, Type B. I never saw either of those photographers use a single flash for anything other than straight news stories or flash fill. Both were "real" photographers, one of which was nominated twice for Putitzer Prizes. He is no longer among us and the other is the same age as I am and has a hard time getting out of bed in the morning as do I. They were using electronic flash (Wabash) in the 1940s. Don't believe I ever saw one use a flashbulb. Those were for us Amateurs as we were known in those days. My point, don't fool with flashbulbs. Electronic flash has been around longer than most of you have been alive......Regards!
