I'm excited to report that I just added a gallery at http://www.photosbychriscoffman.com that features photographs of landscapes and animals from Arizona in the southwest region of the United States. Locations within Arizona include Lost Dutchman State Park and the Superstition Mountains outside of Phoenix; Tonto National Monument; Lake Roosevelt; the Grand Canyon; and Saguaro National Park near Tucson. Prints are available in a variety of sizes, and royalty-free downloads are available for commercial use for all images in the Arizona gallery.
I personally process all of my digital images from RAW files using a combination of features in Apple iPhoto and Adobe Photoshop Lightroom. Currently I'm at work on a wide variety of images I took during a June 2013 trip to Alaska's Denali National Park. Some images of Mount McKinley from that trip are already available for sale as prints. I expect to have a broader selection of images from the park ready for sale in mid-August.
In the meantime, I hope you enjoy my photography from Arizona!
