When I was just a little boy, my Mom brushed my teeth while teaching me how to take care of them. Soon enough I graduated into a self-sufficient tooth brusher. It never occurred to me to let somebody else do this job until I came to this country and learned that I should go to the dentist at least three times a year and let the highly trained professionals do the job. I have to admit that they do better job than me. :)

Here, Susan LaBounty, my dentist extraordinaire, is checking to see if I need any extra work before my next cleaning appointment.

Taking pictures in a situation like this is not easy.
First, I asked for a permission to do it, and promised no flash photography. Ban on flash is a good idea for a safety reasons - do you really want to startle and blind a person with sharp objects inside your mouth?
Second, these are bright lights. Super bright. I had to adjust my EV to -2 in order to see anything. This means that a quarter of the light was used from what the camera measured as good average. It was really hard to adjust all settings just right, and make things properly visible.
This brings us to the third issue - accessibility. My big camera has better dynamic range than my pocket camera, but did you ever tried to hold a big camera in a stretched hand, aimed at you, and press the button at the same time? It is way too heavy for this job. Small camera couldn't flip the screen, so I had to guess the direction with no direct feedback. Changing settings with one hand, while somebody is literally in your face, is not easy either.
Fourth issue was which settings to use. I tried No-blur mode initially, to realize that I have plenty of light, and no flash is not really a limitation in this case. I attempted HDR hoping to level my overly lit face and the rest of the environment, but average was still wrong, and I couldn't adjust EV in this mode. So I settled for good old 'P' mode with flash off and EV set to -2, zoomed half way, turned on multi shot on slow, and took almost 50 pictures by the end of the hour. They were amused but not annoyed - so it was all OK.

My teeth are now clean and I won't brush them again until bed time. :)
