On flicker, especially, I'm noticing blockiness in the sky. I suspect that I've got my jpeg quality turned down too low for a photo where I'm pushing things this hard.
I suspect that these photos will go into the file marked Near miss, try and learn from them. I'm not sure, however what I can learn from them other than that I occasionally run up against the limits of skill or equipment.
