Can I enter a photo into more than one competition?

Yes. There is nothing to stop you from entering the same photo into more than one competition.

Most of the competitions are judged by different judges. When a judge views the photos in a competition there is nothing next to each entry saying that this photo has been entered into another competition. Saying this though, our judges are free to browse through past competitions and if they know that a photo has already won a previous competition then there is the possibility that this will influence their decision making.
