The photographer must hold the copyright to all images used in composite photographs submitted to the Digital Art category and to all stitched images in a Panorama category submission. The use of public domain images as part of a Digital Art submission is prohibited. Photographers retain ownership of all copyrights. Photographs that include sculptures, statues, paintings, and other works of art will be accepted as long as they do not constitute copyright infringement or fraud. Any Photos of the Day meeting legal challenges from either copyright or insufficient model permissions will be removed and replaced.
Digital camera add-on lenses, filters, and scopes are permitted without restriction.
Contestants are allowed to use photo stitching software only for the Panorama and Digital Art categories. Furthermore, contestants may submit images cropped into a panoramic format from a single photograph into any category. Color images may be converted to grayscale or reduced to one color channel for submission in the Black and White category or other categories. Other monochromatic images, such as sepia or similarly toned images, are also allowed in any category. Images in this category are to be close-ups, regardless of the methodology used.
