This past Thursday, I had an assignment to cover former Senator Scott Brown's announcement that he is a candidate for Senate from New Hampshire. Normally at a major political announcement, the campaign would set up lights for TV and stills. Not in this case. The announcement took place at a large conference room with a low ceiling in Portsmouth, NH. If you have ever photographed at any conference rooms in hotels, you would know the ambient light in the room has yellow-green tint. The announcement was set late evening, so no day light was coming in from the window. I had a few options on covering the event: 1) bring the ISO way up and shoot available light, 2) shot strobe on camera (which I did, when he worked the crowd) or 3) add a good portable strobe, run it off a battery and shoot at very low ISO, which will give me very good quality. I went with #3 during his speech.
I set up a Dynalite Uni portable strobe, powered by a Jackrabbit battery on the right side of the stage, triggered by a PocketWizard Plus III. The strobe is 320 WS running off the battery on 1/2 power giving a recycle time of about 1 second.
Here are the results.
Here is another one, after the announcement. This photograph was shot with a speed light on camera.
