I recently discovered the work of Jason Waicunus, a photographer based here in my own back yard of the Pacific Northwest, USA. Jason not only makes stunning landscapes and nature photographs, but is also a travel photographer and teaches classes and leads nature-based photo tours here and elsewhere. Jason is one of few photo guides with a permit to access federal land and is a Pacific Crest Trail hike veteran. I haven’t utilized his tour services myself, but he has excellent reviews.
