Stephen is a very good friend of mine. We both went to Deep Springs College in the mid-1980s, and he introduced me to large format photography one day with what I think was his 4x5" Wista. I decided it was too small and went straight to 8x10".
Anyway, he eventually settled on two Deardorff Specials that were of somewhat different vintages, and Ken Hough was working on them for a very long time so they could be 100% compatible with each other and share parts, and so that one camera would serve as a backup for the other. While this was going on, I lent Stephen my 4x5" Front-Moves Gowland PocketView and probably a 135/5.6 Symmar convertible and a 90/6.8 Angulon--nothing special really--and he may have used some of his own lenses as well. I also sold him a few boxes of Provia 100 that I got at a good price. More recently, I sold him a Sinar F with a bag bellows, but I don't know if he used it on this project.
Stephen's digital work is done by David Adamson in Washington, DC, under Stephen's supervision. Adamson is a real pioneer in the field of high-end inkjet printing and does fine work. I've seen some of the prints, but I haven't seen the book yet.
More important than his equipment, though, is that his parents had a house out in Sag Harbor where he spent summers growing up, and he had an arts residency in Orient, NY, so he really knows that area well--its architecture, history, and its people--and has strong personal connections to eastern Long Island.
