Ok, I realize that not all is well with these shots. I was merely experimenting with placing the camera in the midst of the pigeons while they gobbled up our French fries. It did turn out to be a somewhat expensive mistake. Leaving the camera on the gravel dented the rim of my lens, causing its status to fall from “in mint condition” to a relatively less desirable “excellent”. It fetched a few £s less than it would have in the second-hand lens market.
