Here's one from last winter -- shooting a new retail outlet (Eddie Bauer) 5 days before Christmas Day, in San Francisco's busiest shopping district....so exteriors were, uh, DIFFICULT. Normally I'd go with multiple exposures and plan to blend in areas with no people. In this case, there was a solid crowd of people streaming past, non-stop! Shooting from across the street was pretty much impossible because of the non-stop cars and people crossing in front of me. I moved close, and my assistant tried to go stop folks long enough for me to shoot, but they were coming from like 3 different directions, haha! Eventually he was able to break up the crowd enough for me to get mostly what I needed, and I photoshopped out a few tourists to get the final. Sheesh!
Fortunately, we were able to shoot the interiors during the wee hours of the morning.
