Some days are harder to get a photo, I get shy about taking photos, or I'm too busy enjoying the moment to want to step out of it and take a photo. That's probably the main thing about taking photos that I'm not fond of. It takes you out of the action, separates you from what's happening in front of you. Seems funny considering that it seems like you'd be even more attentive and more aware of your subject, but that's not true. As soon as you bring in a camera, your attention is on framing, timing, lighting... and if you're photographing people, they always tense up and stop doing whatever it was you wanted to capture, either in embarrassment or to pose.
So last night, I realised that a whole day passed and I had nothing for the day. Mike was drawing and I could just see him beyond the fan and monitor. I set the camera on a 2 second timer, put the camera on the table and hoped for the best. I quite like the result, even though you can't see his face, his hand is there, the mouse looks enormous and the light in the background brings your eye back around the image.
