Attended the Calgary Children's Festival today with Luke's playschool. Luke was hanging on me the whole time so it made taking photo's a little difficult. That as well as being told that we were not allowed to use flash in the theatre made it a challenge. However the Canon 7D performed very well in the constantly changing light as I set it to 12,800 ISO and aperture priority. Using the 24-70 f2.8 set at f4 the camera choose 1/250 sec. I set the white balance on Auto and let the camera do it's thing. I liked this one as there was some movement and the ribbons were frozen. It was a good time and all the kids had fun.
