Parallelism

Bitterly cold. Blustery wind made it colder still and I wasn't inclined to walk far. These lichen, nearby, are slowly expanding and will no doubt cover the whole rock eventually. I liked this circular one and decided to feature it.

I tried to keep the rock parallel to the sensor for sharpness to avoid narrowing the aperture. Iso was pretty high already and shutter fast due to the aforementioned wind.
