For someone who frequently wields the camera, I have deliberately few. I’ve used many ways of taking self-portraits. Mirrors, shadows, timers, fish eye lens, strangers, you name it.

I was looking for a better angle for some of my shots and found the water also comfortably cold and clear for a sunny day. I looked down (which many people don’t do often enough) and saw a beautiful array of colorful rocks in the lack bottom.
