I have an occasional project to photograph courthouses in my home state of Minnesota. A few weeks ago, I was in Gaylord, the county seat of Sibley County, which has an impressive courthouse and took this photo, here converted to black and white, with a Yashica GSN and Kodak 400 film.
I converted the photo above to b&w because I was getting a color cast on the stone columns. As I tried to figure out what was going wrong, I remembered that I had taken a similar photo with a Pen half-frame (the original one that came out in 1959) and tracked it down. Here is that photo (taken on T-Max 400):
The comparison really doesn't prove anything, I guess, considering different times of year, one of the originals is in b&w, the other is in color, etc. But I was really struck by how well the HF stands up in comparison to the FF version. I've printed it out at 6x9 and it looks pretty good as a print, too. I don't think I'll try to do the whole project in HF (though one 36 exp roll and one 12 exp roll would be more than enough for the 87 counties of Minnesota !); but, I guess it could be done.
