Today is the first day of Autumn. It’s one of two days of the year when the amount of daylight and darkness are approximately equal (1). After today, darkness will occupy most of our 24 hour day until after the first day of spring when daylight will once again fill the majority of our trip around our planets tilted axis.
Admittedly, I get a bit saddened at the thought of shortened days and longer nights but there are other things that happen during this time of year that negate my depressing view. Because of our planets axial tilt and revolution around the sun (2), as our hemisphere moves away from the sun, the leaves change color (3), shadows begin to get longer (4) and, I think, more interesting and, since we are tilted away from the sun, not only does the air temperature get cooler, the color temperature of daylight also gets cooler (bluer). In our busy lives, we may not notice all of these things, however as photographers, these changes make for prime visual fodder and are worth our attention. It may be my imagination, but I don’t seem to notice as many people carrying cameras in the winter as in the summer. I think that if the photographers who favor summer began to notice the visual richness of fall and winter they would be carrying their cameras equally throughout the year.
