In 1971 I was living in Norway, working at the Norske Radium Hospital, and I bought my first proper camera there,
a Pentax Spotmatic. I bought it second-hand and the guy gave me some old film with it.
On my first film I took this picture.
After finishing the film I took it to work and dropped the film into a tank of developer for X-Ray plates.
I didn't know about different films and developing times.
The film came out so black I could hardly see any image on it.
I later exposed it for about 25 minutes in an enlarger and got these images.
