What is Copyright?.....It's a law that protect artists from people stealing their work. All it means is I created the work so it belongs to me. You paid me however, so you can do what you like with the images - apart from edit them or use them for commercial usage or contest entries. If you want to show off your photos on Facebook or anywhere else online, share away, I'm proud of my work!
Commercial Usage is defined as: using images that a photographer produces for commercial purposes. This includes selling or distributing items made from the images. You pay for the license only once, and you can use it forever without any further payment obligations but I retain the copyright to the images. “You are acquiring the right to use a photo in anyway you want, not the property of the photo itself.”
