I've gotten some really good recommendations and advice here, so I'm back for more.
I've been reading "Photographing Buildings Inside and Out" by Norman McGrath and have noticed that for interiors it is essential to have some strobe lighting to supplement and bring out dark areas in a room. McGrath mentions that he uses Starflash Balcar units with 3200 watt seconds of output. I'm looking for some additional recommendations, as well as some guidance on how to look for this equipment on the used market.
Secondly, it seems as though most of his pictures have some sort of filtering on them, and I'm beginning to think it's time to get some filters because I'm certain to encounter fluorescent light or some combination of daylight/tungsten lighting in my work. Anyone have a pick for filters that fit a Sinar F1? Also, what do you think about using Photoshop to correct lighting in some cases? Is it relatively easy to correct daylight on tungsten film (and vice versa?) In as many cases as possible I want it right on the slide/negative, but there are always times when you have to work with what you have, compensating in the print for what lacks in the film.
Okay, so that's a lot of stuff. Feel free to pick it over and respond to your favorite parts...
