Enjoying the course. More people are commenting on each other's images, and showing off their newly-learned technical knowledge along the way.

All sounds good Rob and a nice image to illustrate it with too. Not only a good use of selective focus and shallow DoF but great gradation too.

Love that image - course sounds like it's providing excellent input and stimulation
