Urgent! What is the best prize in the non-professional photography competition?

It is suggested that the photos of the top three winners be developed, framed and given to them, or hung on the exhibition wall of the company to make employees proud of it forever. Make sure the first one is bigger and better and the second one is smaller. Then the first one can get a better travel bag, the second one can get a camera bag, and the third one can get an insulated travel pot (cup). So 500.300. 150 should be enough!
