Every fall, the leaves of deciduous trees undergo a dramatic color change before forfeiting their newfound hues, fading to brown and dying. The process can take weeks, but Owen Reiser, a mathematics and biology student at Southern Illinois University Edwardsville, wanted to see the leaves change in a matter of seconds. “I was taking a field biology class and we were learning about deciduous trees,” he says. “I’ve been getting into wildlife photography and time-lapse for a while, and I couldn’t find a time-lapse of leaves changing color, so I just went for it.
