Smiling for the onlookers

Stopped at a small local museum and park this morning on my way home from a night of 'graveyard' ...(third shift) to work on different settings with the D40. Still trying to learn. :) While there this photographer and assistant arrived with the pair of subjects to do a high school 'senior days' photo shoot.I love catching moments like this of photographing the photographer. Afterwards I thanked all for allowing me to be part, albeit as unobtrusive as I could manage, of their activity. Always a learning experience as well as a lot of fun.
