I'm hoping you guys can give me some advice. I've been tasked with managing our company's photo contest this year. Every year we invite thousands of employees and clients to submit their shots for our contest with the winning shots being used in our annual calendar. There have been some silly requirements in the past that have resulted in entires that weren't high enough quality to use in the calendar...and good submissions missed out on a chance to win.

So here's question #1: I'd love any advice you can give me on how we develop our requirements for submission. Keep in mind the images will ultimately be used in a 9"x12" calendar, so the closer we can be to final, printable dimensions of 2700x3600, the better.

Second, we're considering limiting entries to digital submissions only. In the past we've accepted just about anything people wanted to submit, but we think the time has come to focus solely on digital (at least in part because it makes the management portion of the contest much easier).

Any advice I can get would be HUGELY appreciated!

Thanks!
Jon
