I may be moving to PANS, at least indoors. They had some decent light at ICP, so got by with 1/60. But some shoots at the galleries / museums it is handheld at 1/8 second. And if the pans don't work out it is no big deal, I got the fisheye.
Always good to have a list of rain day stuff. Tons of galleries and museums in NYC. Or go underground and shoot in the subway or Grand Central. I did about 20 min in BH shooting infrared flash when I got rained out. The ICP has an impressive amount of classes and teachers.
Here is an interview of Cornell Capa who founded ICP.
