Bryan Peterson has been a successful comercial photographer for over 30 years. His clients include American Express, Kodak, UPS, Philips and Citibank.

Andy loves photography, and sharing his knowledge and experience.  One of the true "internet gurus" of photography, he's been around for well over 10 years helping photographers all over the web forums, and most notably on DPreview and Digital Grin.  There, Andy not only helps thousands, but has recruited many outstanding contributors to the community.  It was at Dgrin where these Workshops have their roots.  Andy led the first Dgrin workshop in 2005 at Yosemite, where Andy asked Marc to join the group.  Then it doubled in size as the group went to Bryce and Zion in 2006.  And then, Glacier National Park.   Over the years, Andy and Marc have developed a close working relationship, and both share the ultimate goal of "passing it along" to their workshop students.

What has become evident over the years is that Andy not only excels at his craft, but at teaching others.  Andy has an ability to distill complicated subjects down to practical methods that his students can employ immediately.

And he'll stay with you, after the workshop, to the end :)
