I work in a camera store. So naturally I see a lot of different photographers passing through. I started to get in the habit of keeping a loaded camera nearby and snapping candid portraits of some of the customers I worked with. This is one of the photos in this series which I have titled "Once in a Blue Moon" named after the store I work in (Blue Moon Camera and Machine).

The rest of the series by the way can be found here on my Flickr site.
