Videos are nice, but generally you need to be relatively skilled on bocks or be a skilled video editor to do one and also they are better usually when its of a group meet, so disadvantages the lone wolfs out there. But I was thinking, one that is relatively fair for all people, is a postcard cover? Maybe each person submits 3 postcard covers with the photos being their own, so no Google searches! Maybe run the competition till the end of August to give people the time to find the right sunset and conditions etc.
