I find it difficult to choose which pictures to use for each assignment because I keep finding something wrong with each of them based on the previous assignments (crooked horizon line, shutter speed, white balance, rule of thirds, unimportant things out of the frame, etc.). So, I guess I'm learning. And I think the lessons are great. My photos are improving but I am having problems focusing. I hardly use a tri-pod (it seems much faster without it), so maybe I need to stop rushing my shots and use one.
