Good & Bad

This would be an example of a "good" photograph submission.  White mat, 8x10 print.

Another nice photo; matted in white, print size meats the 7x10 inch minimum.

Although the presentation would possibly be done without the stand, this photo is properly matted and would meet the minimum print size of 7x10 inches.

While the photo is striking and the mat is white, frames are not allowed.

Matted and not framed, meets the minimum size requirement but the mat should not be black.

This is a lovely photo that deserves a prominent place in a home, however, it does not follow the guidelines for competition; no frames.
