Officers Rowby
bvyComment by bvy: The houses are beautiful. Huge rooms, mile high ceilings, gorgeous woodwork, windows, etc. There are about twelve of them, but only one is restored and can be toured. They all have bad roofs. Story goes that when the military turned the houses over to the state park in the 1960's, they did the park a "favor" by first tearing off the 75-year-old (or so) slate roofs and installing shingles. The slate roofs never leaked; the shingled roofs started leaking after ten to twenty years. The park can't afford to replace them, and now all the houses suffer water damage.
As far as the photograph, I never thought of this photograph as terribly sharp. As far as what makes a sharp pinhole photo, I think the key is a thin, clean, round, optimal-sized hole. The shorter the focal length, the smaller the hole should be, but it's not a linear relationship. There are online calculators that will give you the optimal sized hole for a given focal length.
Having a solid camera is another variable that people overlook. When you're talking about long exposure times with cameras made of flimsy material such as cardboard, camera shake happens easily.
