When I was at the Rochester Institute of Technology, one of my professors discussed the ‘Ratio of Success’, which defined how many photos you typically took in order to get a really good one.

By one standard this averaged about one per roll of film. Or a ratio of 1 to 36.

For the last three days on Tracking the Light, I’ve been displaying photos from a single roll of Kodak Plus X exposed on Conrail’s former Pennsylvania Railroad lines back in the summer of 1989.

I wouldn’t want to bore everyone by displaying all 36 frames, but lets just say, on this day I was having a better than average ratio of success!

This one portrays a Conrail unit grain train descending ‘The Slide’ east of the tunnels at Gallitzin, Pennsylvania.
