From Newgrounds Wiki:
"Photography is not allowed in either public or private galleries. We prefer to keep the spotlight on hand-made works. Photographs of sculptures, paintings or other hand-made items are acceptable; here's a guide for photographing your art. Filtered photographs are not acceptable. While we respect tracing as a teaching tool when source images are fully reported, please use places like your blog to share traced images, rather than the Art Portal.
You may submit collages with photographic elements, providing they constitute a new work of art with handmade elements. If possible, please post links to any photographs, or elements of the collage that were not made by you, to help us determine if the submission is suitably transformative."
The only photos I post here are on my blog entries and never on the art portal unless I take a picture of a traditionally made artwork. I love photography, you will have a lot of fun^^
