I just posted a pic to Flickr yesterday in which I intentionally included my shadow in the photo. I didn't post it here because I didn't take it with a Pentax.
I wanted to get the shadow of a "torii" gate (the kind that marks the entrance to Shinto shrines in Japan), but the length of the shadow combined with the 38mm lens on the camera meant that I had no choice but to include myself. My first inclination was to not take the picture.
But then I thought back on having grown up with a family whose entire involvement with photography was family snapshots with Instamatics. They grew up in the first half of the last century with Brownies and the only thing they knew about photography was that shooting into the light was a big no-no. Folks like that tend to end up with their shadows in the pictures quite a bit.
So as my little way of reaching back across the decades to my roots and showing some props to my dearly beloved departed grandmother.....I purposely included my shadow in the photo. On my Aminus3 photoblog I titled it
Family Tradition.
