Its time to start collecting images on film. 35mm isn't going to cut it and 120 seems like a fair trade. Like so many railroad photographer who came before me: 4x5 seemed like a really good idea. I found a Linhof view camera in Troy for $120, replaced its bellows, and found a good 150mm lens. Shutter synced up with the strobes nicely. However, a view camera is completely impractical in the field: its big, there are tons of knobs and fittings to snag and you can't set it down on the ground.
