It's great when your subjects happen to sit still. And it's even better when you know they will. That's the charm of still life photography.
We got some tulips recently from a friend and just before they wilted, they screamed, "Take a picture of us! We'll bend and twist and look our best, even if you put a black sheet under us!" So I did.
And then when the sun shone in through the kitchen window, I just couldn't resist taking a few more. And we were all happy.
