I am doing a project where I photograph people in the subway. I love to record their expressions and faces. The camera is a Nikon F3 from which I remove the prism, so that it becomes a waist viewfinder camera. People often do not notice me, even though I sit right across the aisle.
Lately, though, I have found those photos more interesting where I am noticed and people accept that I photograph them.
Have a look at my results, if you like
