“Today, we take photography for granted. Anyone can take a photograph simply by pressing a button. Yet, it was not always so simple. The invention of photography was announced in 1839, but during its first fifty years taking a photograph was a complicated and expensive business. In 1888, all this was to change following the appearance of a camera that was to revolutionize photography. Popular photography can properly be said to have started 120 years ago with the introduction of the Kodak”. – The UK National Media Museum. Photo: Two men on the deck of a ship, about 1890.

Kevin Russ, a photographer & image moderator for iStockphoto, grew up in Arroyo Grande, California. In 2003, he made the move to Portland, planning to study at Multnomah Bible College. Finding the workload to be minimal, Kevin invested in a camera, filling his free time and finding himself instantly smitten with the craft. A year and a half later, photography had evolved into his full-time job. However, after 4 years of consistent portrait work, Kevin became burnt out and took a step back from photography altogether. Two years later, he picked up the camera again and now spends the majority of his time on the road, exploring & photographing the rustic landscapes & wildlife he encounters.
