The Open category is the broadest and most general Category. There are no restrictions on subject matter, technique, or digital editing as long as the image meets the basic requirements for all submitted images.
Images must be in jpeg format, no more than 1920 pixels wide, and no more than 1200 pixels high. The recommended color space is sRGB. Images may be color, infrared, or monochrome. All images used must have been taken by the maker. (For example, do not use a sky provided by Photoshop if you use the "Sky Replacement" tool.)
All rights reserved. Request prior written permission from the photographer to reproduce their images.
