[UPDATED - 10/3] Three new images have been accepted at Shutterstock.
These images are from a collection of photos taken on a recent trip with my family around the Southwestern states of Arizona, Nevada, southern California, Utah and Idaho. Two of the three approved are landscapes from Zion National Park. The third is from the Glen Canyon Dam.
These three images were submitted to several other sites, as well. I'll update this post should the be accepted elsewhere.
I am still working on several other images from that trip that I hope to submit in the near future.
