I generally like to take photographs using available light (admittedly I am somewhat lazy and this is the easiest thing to do).
However sometimes, there are advantages to eliminating the available light completely from the scene, then highlighting certain points with the use of an external flash.
Intrigued? I will explain.
This fluffy seed pod of Clematis ‘Dr. Ruppel’ covered in a light dusting of snow caught my attention but appeared very blah when shot at normal exposure (light-colored pod against overcast sky = uninteresting results).
But, when I purposefully underexposed the image, creating a very dark background (almost looks light nighttime, eh?) and then added in a fairly strong pop of flash, Voila!
One pretty nice photo! 🙂
