I teach classes in photography (basic and portrait) and scrapbooking through the Chandler Community Center. You can find the classes on line. Once you're on the Chandler site, click on the "Leisure and Lifestyle" link and then search for "Break Time" catalogue. You can also contact me directly if you want more info about class schedules or content.
Photo.net is a great place to learn about photography, view photos from others, and upload your own photos to share and critique. You can find my pictures on-line here under my married name (Jennifer Valencia) at http://www.photo.net/photos/Jennifer%20Valencia
Photomark is another large photography store in Phoenix; they also sell, rent and do photofinishing. I like the one on McDowell b/c it's HUGE. Also, there is a fantastic Polish deli/sausage shop across the street called Stanley's.
