Capturing Enchantment: The Quest for Optimal Photography Light
Written on
Chapter 1: The Allure of Magic Light
The pursuit of exquisite light for photography often feels like chasing shadows. After enduring a strenuous journey, I finally managed to capture an awe-inspiring image deep within Colorado's wilderness.
As I sat in a mix of anticipation and trepidation, I observed nature's forces at play—an intricate process that transcends human comprehension. The energy being released had been building since time immemorial, stretching over vast distances and representing a terrestrial force that far exceeds anything humanity could create.
Crouching beneath a tumultuous sky, I felt the atmosphere crackle with potential. A sudden flash erupted, followed by the rumble of thunder. The winds swirled around me, unleashing a torrent of rain. The stakes were high; a misfire of this natural spectacle could spell disaster. Yet, as time passed, a hush fell over the landscape.
Did it all unfold as hoped?
What was it that I truly sought?
Light… magical light.
That was the very reason I had ascended to this precarious height of 12,600 feet, waiting for the storm to subside.
Chapter 2: Myths and Legends of Light
The sun, a central element in humanity's quest for understanding, has long influenced our beliefs and perceptions of existence. In the Sumerian epic, The Epic of Gilgamesh, the protagonist embarks on a journey through the sun's gate in pursuit of eternal life. The Greeks envisioned the sun being drawn across the sky in a chariot by Helios, their sun god.
Some ancient civilizations approached the sun with a scientific lens. For instance, ancient Indians made astronomical observations as early as 2000 BC, documented in the Rig Veda. By 500 AD, they had identified the sun as a star orbiting other celestial bodies. Similarly, in 1279 AD, Chinese astronomer Guo Shoujing established an observatory to explore solar phenomena.
“The purpose of life is the investigation of the Sun, the Moon, and the heavens.” — Anaxagoras, 459 BC
Section 2.1: The Nature of Light
Despite our extensive scientific knowledge, light remains an enigma. In the 17th century, Isaac Newton classified light as a particle. A century later, Fresnel and Young demonstrated its wave-like behavior. It wasn't until Einstein's groundbreaking work in the early 20th century that light was understood to exhibit both characteristics.
Light, comprised of massless particles known as photons, travels at a staggering speed of 186,000 miles per second. The visible spectrum is merely a fraction of the broader electromagnetic spectrum, which also encompasses ultraviolet, infrared, gamma rays, x-rays, and radio waves. What we perceive as white light is actually a combination of all colors.
In the first video, "Stories from Nimmo Bay | Chasing the Light with Jeremy Koreski," we delve into the art of capturing light in nature, exploring techniques that enhance our photographic experiences.
Section 2.2: The Art of Photographic Light
Each color possesses distinct properties that interact with the atmosphere in various ways—through diffusion, refraction, and reflection. This is where the concept of magic light for photographers takes shape. In The Art, Science, and Craft of Great Landscape Photography, Glenn Randell explains how to harness these interactions to increase the likelihood of capturing stunning images.
Most people know that sunrises appear red and the sky appears blue due to atmospheric scattering of light wavelengths. However, Randell provides deeper insights. He highlights a phenomenon called Rayleigh scattering, where light is dispersed by particles smaller than its wavelength, such as nitrogen or oxygen molecules in clean air.
When the sun is directly overhead, light travels approximately 11 miles through the troposphere before reaching the ground. In contrast, when the sun is at the horizon, it traverses around 235 miles. Ascending to high altitudes with an unobstructed view to the horizon allows light to journey even farther, resulting in the vibrant hues of alpenglow.
Section 2.3: The Role of Reflected Light
However, light scattering doesn't always yield beautiful colors. Nowadays, larger particulates—such as dust, pollution, and smoke—often scatter light, especially during wildfire season, resulting in a monotonous gray illumination.
This is why the aftermath of storms is so crucial. A significant rainstorm can cleanse the air of these larger particles, allowing for the emergence of vibrant light.
Rain not only clears the atmosphere but also creates clouds that reflect light beautifully. If a peak turns crimson at sunrise beneath clear skies, the foreground may be cast in dull blue light. Yet, when clouds are present to reflect warm sunset light, “glow” conditions arise, creating dynamic compositions that enhance visual interest.
The second video, "Magic Light - Quick Demo," showcases techniques to identify and capture magical light conditions in various environments.
Section 2.4: The Science Behind Rainbows
Water droplets, though larger than dust or smoke particles, refract and scatter light systematically. When white light enters a spherical droplet, the average angle at which the separated colors exit is 42 degrees, resulting in a circular rainbow. If viewed from a high enough vantage point, a rainbow appears as a complete circle, although the ground typically obstructs the lower half.
Randell offers calculations to predict rainbow locations relative to interesting foreground subjects and practical advice on estimating where a rainbow might intersect with the horizon.
The paradox of pursuing magical light is evident: widespread clouds can both diminish your chances of success and enhance the quality of photos when conditions align perfectly.
The Aftermath
As the rain's rhythmic patter on my tent subsided, I sensed a change; the interior felt lighter. Peeking outside, I noticed the tumultuous clouds beginning to disperse. The sun, though still partially hidden, was approaching a clearing in the sky. I quickly grabbed my camera and tripod, making my way to the ridge's northern edge.
There, I spotted a fragment of a rainbow in the valley below. Recalling a patch of yellow wildflowers I had seen earlier, I slipped down into a small ravine and captured the moment.
Achieving the ideal combination of light, subject, and composition requires a blend of persistence and serendipity. While it may seem daunting, the beauty that unfolds in such moments can only be described as magic.
