Good Oral Hygiene Is Very Important
You might get the impression from this picture that Jason is good at brushing his teeth, but he's usually much more interested in rinsing the toothbrush than actually using it on his teeth. After his bath, I get him to stand on a little stool in front of the sink, then I floss his teeth with one of these. Then I hand him the flosser, which he plays with for a few seconds before dropping it in the sink. I pick it up and put it in the trash can, then brush his teeth thoroughly. When I hand him the toothbrush, he scrubs it across his front teeth once or twice, then holds it out to be rinsed. If I'm lucky, I can convince him to take a couple more strokes, but that's about it.
Technical information: Shot with a Nikon D40 and Nikkor 35mm f/1.8 DX lens, in aperture-priority exposure mode. Aperture f/2.8, shutter 1/125 sec, ISO 1100. White balance set in camera to tungsten. Lighting is just the normal wall lights above the sink. I used Aperture 3 to rotate the image 90 degrees, but other than that, this is straight out of the camera.
Thoughts for improvement: That highlight on the countertop is very bright and distracting--it would be much better if I had taken more time to compose the shot to avoid it. Other than that I'm pretty pleased with the results. I set my Auto ISO settings for a minimum shutter speed of 1/125 after losing a bunch of party pictures last weekend to motion blur, and I think that works pretty well for photographing young kids, who generally won't hold still for a longer exposure.
