I am proud to be a member of a group of the worlds best digital artists. I am a student in this class learning how to create composites from my photos. While this group of amazing artists are the best at what they do, most are not photographers. So, I am providing many of the artists in this group edited and unedited model images to be used in their composites. These world class editors only make our work look better.
I actually do this in a couple ways. By providing the group/class 20 images per month, my fees to take classes are waived. Additionally, for those artists who choose to, can purchase additionally images from various stock photo sites.
As the photographer and copyright holder of my images I am fully within my rights to do whatever I wish with my images, including selling or licensing them. On the other hand, I also pass through commercial rights to my models so that they can also sell posters, prints etc etc.
