All submissions to the Society's (OPS) annual exhibition must reach the Society by the advertised entry date. Each photographer's submission must consist of images emailed to the Society and payment on-line of the appropriate fee. Entries cannot, under any circumstances, be accepted after the declared cut-off date or without payment of the appropriate fee. Since all material submitted to the exhibition must be in electronic form, no images will be returned to authors. Once the exhibition has been completed, and the Society has no further exhibition-related need for submitted images, the relevant files will be deleted.
