Last weekend I shot basketball at a local area High School with my two new WL X1600 strobes - for the first time. I was not able to get on the court to take a light meter reading to set the f stop. by metering. I aimed the strobes (placed at one end of the court) at the ceiling for a bounce effect. I fired the strobes at 100%, and shot at 1/250 second, synch speed. Focus was fine, but many shots were blurred - If I shoot at 1/1000 this coming weekend, is there a "formula" for determining f/stop, or is this a trial and error situation. My favored ISO is 200 and my lens of choice is an 85mm f2.8.
