These are "unofficial" because they were taken on the night when we were having dinner and working out the details. We were talking outside after dinner and I started to see that the sky was looking just right for something I had wanted to try out. I decided to go ahead and ask them if they would experiment with me. I was not planning to take any photographs that night but, I try to always have my equipment with me (you just never know). They were up for it and as a result I came away with a few images I really liked (and will be sending to them) and some practice with a technique I had not been able to play with yet. Moral of the story... always have your camera ready to go.
