This is the very first photo I took where I had the actual intention of playing with the light. It is the 52nd 35mm frame I ever shot in my life, #15 on my second roll!
I had asked my dad for a better camera than the 126 Instamatic I had gotten for a birthday some years earlier, and he dug out his old camera and told me to give it a try. I think it was a test....
The camera was a folding rangefinder, a Voigtlander Vitessa, with the Ultron 50mm f:2 lens. Shutter from B to 1/500, aperture from f:2 to f:16. No meter built in, I carried a handheld light meter. I still have the camera and the meter, and they both still work.
For this particular shot, I pointed the meter in several different directions, mentally guessed an average, realizing that the reading towards the brightest reflection ought to be ignored, and then set for 2 stops underexposed.
This was in January of 1980, and it remains my one favorite "own" photograph of all time.
Unfortunately, while the Kodachrome holds up color-wise, the film is not flat in the slide mount, a little bit wavy, so my film scanner doesn't get the entire frame sharply focused, I don't know what I can do about that, other than unmount it sandwich it in glass, but I imagine that would introduce problems of its own.....
