Besides equipment, lighting, composition, exposure, parking, etc. there’s another factor to consider in on-location portraiture: traffic.
A usually-quiet parking lot seemed to have more traffic than downtown Seattle as I was making a nighttime portrait of a local engineer the other night. Neither the subject nor I had anticipated the number of cars driving through the background and, on several occasions, nearly hitting one of my strobes. Apparently two flashing strobes, two people and a tripod aren’t’ enough to alert some drivers in downtown Yakima.
Admittedly, I probably wouldn’t have had the same problems had I been working in the daylight. But this photo needed to be done at night so the street lights would show up in the photo.
If I had known there would be that much traffic I might have picked another location. Or, gotten some reflective traffic markers to warn drivers. More stuff to add to the location lighting kit…
