"That has really changed my life," he said. "I can get on the airplane with one rolling bag and one small sling bag with light stands, and I have an entire studio with me on the plane. I can travel with six Speedlights and do just about anything I could do with those four big heavy cases I used to travel with."
One thing about using lights that are so small is I can put them anywhere. I can put them under a couch. I can put them up on a ledge. I can hook them to a bookshelf. I can stick these lights just about anywhere. With studio light you just can't do that."
Bergman shot four World Series games, again turning to the Nikon D700 "and my favorite Nikon lens, which is the NIKKOR 200-400mm zoom."
Each of the resulting images, shot from centerfield, actually comprises 675 individual photos shot over 53 minutes.
"When you stitch these together into one giant photo it's ridiculous," he said. "It would be nearly 30 feet wide at 300 pixels per inch."
He almost makes it sound easy. Bergman knows, however, that a good picture is hard work, whether you're shooting a stadium filled with baseball fans or just the family.
"When I pull out the camera it's because I want to make a picture," he said. "I'll go through the extra effort because I want to make pictures that people remember."
