Susan Koehler

Photography has always been a hobby of mine. I capture the moment as I see it from my angle and share with the world how I see things.

Susan Lehrer

I appreciate the – often unconscious – documentary aspect of photography, which can evoke a specific place in historical time, as Gunks Through Time illustrates. I enjoy going outside, photographing the natural world, looking for particular views or angles, seeking to create images capturing my sense of wonder and the beauty of this amazing place.
