Stock Shot Project

I needed to take a photo of a camera with pop-up flash for my DSLR teachng website, and decided it would also make a good stock photo.  Originally, I planned to do this in two shots -- one of the camera with flash and one without -- and combine them.  As it turned out, I was lucky with my timing and captured the exposure with flash and pre-warning timer light in just one shot.  This was due to the fact that I used a very slow shutter speed that was long enough to capture both lights.  The subject was lit by the pop-up flash on the Nikon D7000 I was using to photograph this.  Lens was a 50mm at f/16.  Stopping down to f/16 allowed me to use the slow shutter speed of 1/2 second that captured both flash and warning light.
