I'm in a hurry to take part in the photo contest. Please give me some common sense about the photos of the contest, such as size, how to add comments and so on.

Usually. General ten-inch film, size 10X8 inch (25.4X20.32cm), special-shaped film, which is not allowed to exceed 80 square inches. Please submit it for printing according to the drawing. Words are not allowed on the front, and photos are not allowed. Fill in the form as required and stick it on the back.

According to personal experience, take part in movies and don't print them smoothly. It is recommended to use textured paper, which has a good texture. Or use micro-spray.
