Shot with my 50mm (the cheap-ass one from Canon f1.8) at f2 and an exposure bias of 1 full stop in order to keep the dark bits as they should be. I took the quick, lazy option of shooting Av because I didn’t want to risk losing the moment. After setting things up quickly it was just a matter of focussing properly (not always easy with this lens: it is rather poorly built, but so is the 5 times more expensive f1.4), getting the right frame and start clicking away!
Afterwards it turned out there was no need for hurry, Luc loves smiling and took plenty of time to pose for the camera. Out of 30 shots this one came out nicest.
