It’s Christmas time again, and with it we photographers find ourselves photographing something very pure to our imaging instincts: Christmas lights. Beautiful and dazzling to the eyes, we love photographing them for several reasons. They are everywhere, they are fun to shoot, and they summon the children inside us who looked on them with amazement all those years ago.
I think about this as I photograph lights for a living, and last night as I photographed the Christmas tree and lights at home. I did a fun little experiment that illustrates the value of mastering aperture: shooting the same scene at apertures through the entire range. It is powerfully illustrative of the effects of aperture…
Made with my 50mm f/1.8 lens, one of the best and most affordable lenses in anyone’s bag, these three images are identical except for aperture, which, as you can see, makes a huge difference. Wide open, the out-of-focus highlights are round, at f/2.8, they take on the heptagonal shape of the aperture blades, and at f/22, each bright point of light takes on the classic “sunstar” look.
All three of these unique looks has a place in our photography, and all are right there at our fingertips.
