This is one of my favorite underwater photos from the Ecuador trip. We were swimming with the sea lions and they were moving into and out of a shadowed area caused by a nearby cliff. Whenever they went into the dark area I was getting pretty slow shutter speeds due to the lack of light. Knowing this, I tried panning with their movement as they swam below me. On this particular exposure, I was able to keep the focus point on the sea lion’s head to get sharp focus on the eyes while blurring out the colorful background.
