He started becoming serious with his photography winter of 2007 when he first acquired his first DSLR as a documentary tool for his backpacking trips. Equipped with this tool, his time spent outdoors is now focused mainly in capturing the fleeting moments in nature not commonly seen by others. "Fleeting moments" could mean that small window of time when a light shaft enters a slot canyon, or the precise position of the sun illuminates a brilliant ray splashed across canyon walls. It could mean that dramatic evaporation of gas in a frigid sea when warmed by the early morning light. Or it could be that magic moment when a cloud shimmers during sunset.
Retzer is a self-taught photographer. Although he does not limit his photography to just one style, he specializes on wide landscape capturing the "fleeting moments" in nature. This is how, even in an ordinary location, an extraordinary image is captured. It also means he spends a large amount of his time hiking to those locations hours before sunrise or during sunset and often not yielding a decent photograph. He is grateful to the patience of his ever understanding wife, Lewelyn.
His fondness for nature is not his only passion. Retzer received his Bachelor's Degree in Nursing in the Philippines and currently works at Johns Hopkins Hospital in Baltimore. He enjoys nursing and managing the care of his hospitalized patients, feeling he comes home each working day satisfied and grateful of his blessings.
