Farting around in the high school darkroom with a negative of a guy silhouetted against a window. Stumbled onto the idea of sandwiching a piece of lens cleaning tissue into the carrier with the negative. Got so excited with the result that I took the print into the classroom to show the teacher before it was properly fixed. Had to make another print that ended up featured in that year's yearbook.

Wish I had not let so many years intervene between then and becoming recaptured by photography...
