Recently I dug out my photos from my zone system course when I was in grad school. I had forgotten how tonally rich the prints were. Even when I scanned them in they held their tones. These images were taken around Texas A&M University in College Station, Texas back around 1988 as part of my class assignments. I then developed and printed the images. I scanned in my zone calculator as well as a reminder about how tedious and involved this process is.
