A Progression of Color Canvas Print

A progression of color along the side of the now paved Guanella Pass road in the central Rocky Mountains of Colorado.

When leaves appear green, it is because they contain an abundance of chlorophyll. There is so much chlorophyll in an active leaf that the green masks other pigment colors. Light regulates chlorophyll production, so as autumn days grow shorter, less chlorophyll is produced. The decomposition rate of chlorophyll remains constant, so the green color starts to fade from leaves.

At the same time, surging sugar concentrations cause increased production of anthocyanin pigments. Leaves containing primarily anthocyanins appear red. Carotenoids are another class of pigments found in some leaves. The carotenoid production is not dependent on light, so levels aren't diminished by shortened days. Carotenoids can be orange, yellow, or red, but most of these pigments found in leaves are yellow. Leaves with good amounts of both anthocyanins and carotenoids will appear ora...

Photography is all about using light to capture the emotion and beauty of a fleeting moment. For me, this adventure began with a single spring image using a small Kodak film camera of a freshly watered central Kansas ditch and has come full circle using modern digital techniques. My first camera was acquired by trading an ancient Royal typewriter to a fellow college student who was desperate to finish a term paper. It was a long time ago and that camera was my passport to an art that has fascinated me ever since. I owned and operated a professional studio in central Kansas for 20 years and moved to Colorado in 1994. Part of the studio's early success came from creating outdoor portraiture using controlled lighting...
