Have you checked out the Colorado Photographic Arts Center workshop schedule? They just released their fall offerings.
CPAC Classes and Workshops
The CPAC Photography Education Program is the most established of its kind in the Denver Metro region. Most courses take place at the CPAC facility in Lakewood, CO, approximately 10 miles west of Denver downtown. Others take place at partner facilities – The Art Students League of Denver, the Zang Mansion darkroom in central Denver – and at off-site locations such as Santa Fe Drive. Classes and workshops are geared toward creative development for artists seeking to further their skills and careers; they are taught by a diverse faculty of professional photographers with established careers in the commercial, fine art, and academic markets.
Courses range from 3-hour intensives to 12-hour classes over four weeks, and are divided into three learning levels: Intro, Core, and Continuing.
