Working on that pipeline job last week provided some tough shooting in mid day sunlight. The welding crew work under a blue canopy along side a tracker which carried the juice to run the welders. This was our first day on site and the welding crew was shut down after just a few minutes of shooting. The welding crew was working without a supervisor on site and because of that, they had to stop working.

Apparently, their where a few welders being trained and the on site supervisor was conducting the training. Who knows, I managed to get a few shots before the work ended.

You can see from the photo below, I have clamped a Nikon SB-800 using a Justin Clamp to the overhead canopy. I was firing this strobe using the CLS method.

By fastening the strobe to the canopy, my flash to subject distance remains the same as the crew move down the pipeline. This set up provided consistent flash exposures shot to shot, it also allowed me the opportunity to concentrate on composition instead of worrying about changing flash exposure.
