When I first look through my photos after taking them, the spectacular shots always stand out first: the whale breach, the seal looking curiously right at you, or the bird in flight. Sometimes, however, when going back through my photos again, a more subtle image comes to my attention. Not the animal itself, but where the animal just was. I've started pulling a few of these photos out, calling them "Impression". Here are a few examples, of a harbor seal diving, a pair of raccoon footprints, and a whale breach splash.
