I put my Canon 10D on 3200 ISO just to see what it would do. I was hoping for a grain that would remind me of old BW Tri X I used to shoot. I was very happy with the 'gritty' rendition. Jonah was making up his own songs on a keyboard, and this was the look of concentration he had on his face the whole time. It was very interesting to watch him. He was not looking at his hands/fingers playing the notes, but he was staring into space, in his own little world. His intensity was amazing to watch, especially for a three year old.
