National parks and protected areas are brimming over with water scenes, from glaciers to snowy landscapes to ponds to rivers to misty mornings. Contributing photographer Rebecca Latson provides tips and techniques for how to capture those myriad forms of water (glaciers, snow, ponds, streams, rivers, mist, clouds) in a composition.

Not all park forests are alike. Some forests thrive in moist, even waterlogged environments, while others flourish in much drier climates. Some forests remain green year-round while others burst with color in the fall. Some forests stand as stark testaments to the ravages of wildfires while other forests provide environments for trees to grow to mind-boggling heights and widths. All these forests and their trees flesh out the story of a national park visit and the Traveler’s contributing photographer Rebecca Latson provides example images, tips, and techniques to help you capture the forest story of your own park trip.

Beneath the waves that roll ashore on the Olympic Coast is a symphony of life. Clinging to the rocks and going largely unnoticed by many beach visitors, a cast of characters straight out of a Sci-Fi movie busily move about. It may seem like the most hostile of environments but, to countless animals and seaweeds, it’s heaven on Earth.

When you look at photos you’ve captured during a visit to a national park unit, do you notice one or more of your shots clearly showing a division of light and dark, or energy and calm, or two different colors, or two different textures? Contributing photographer Rebecca Latson sees this phenomenon in many of her own images, calling it the “yin and yang of a composition.” In this month's column, Rebecca provides examples of this yin-yang concept and how you can look for it in nature with your camera.
