I used to ride my sled down the hill next to that stack. Sometimes if there was enough ice on the road, I could almost make it to the bar across the street. Once, my Dad had to stop me from going into the road and getting run over by a car. It was a real thrill as a kid, but the hill seemed to grow smaller, as I grew older! My friends always had to meet somewhere by the bluff, when we were in town. There was as much life as there was death surrounding that place...it supported a lot of families, a bar on every corner and half of the homes surrounding it were built from the same materials, stolen in the thick of the night.
I shot almost the same photo in 1979 for a HS project, mine was from the west elevation and taken from the ground. I like yours better, using the roof top to help draw you into the Cupola. The VA Hospital in East north Port has some beautiful Gothic Architecture as well.
There was an upper mezzanine or balcony up there, with a door to the projection room. It was connected to the third floor of the hospital, with the lower part of the theater connected to the first floor.
I believe this was used as a county morgue, which usually serves a fairly large area, and therefore much larger in capacity than one at a psychiatric hospital.
I use long exposures, which range from 10-30 seconds at around f5 ISO 200, but I've heard many others with shorter exposure times - this might be dependent on the lens being used.
Unfortunately it is often impossible to take infrared shots of places where security is present and there is no time to fiddle with filters, tripods and exposure times... I was thinking of converting an old 300D to an all-infrared camera to avoid this.
