An Entry consists of, up to and including, four (4) images entered by a single entrant in the same Section. A participant can only enter a specific Section once. The entrant may not enter identical or similar images in the same section or in different sections of the same exhibition. Titles: Each image must have a unique title that is a description of the image. That unique title must be used for entry of that image or an identical image into any and all PSA-recognized exhibits. Titles must be 35 characters or less. No title can be visible to the judges, and nothing in the image can identify the creator. Titles cannot include file extensions such as .jpg or .jpeg (or any other camera capture filename such as IMG 471).
