'Amanhecer no Hercules' by Carlos Perez Couto, CC-BY-SA, winner of WLE 2014 Brasil
Unfortunately, nothing is perfect and I have a couple of pet peeves about the contest. First, not once I found myself shouting in my head 'They didn't hear of the rule of thirds in Brasil?' I saw too many otherwise nice pictures with the horizon line cutting the image in half for no good reason, which could be way better with a 'correct' composition. Second, I had the feeling some participants misunderstood the purpose of Wikimedia Commons and sent unedited images: is OK to upload thereedited images as long as you do not change the reality. I encountered a lot of photos which can easily be improved with a few simple edits: framing (crop and/or rotation), color/exposure adjustments (curves, levels, brightness, saturation), sharpening and such. Some photos could made the top 10 if they had be edited as such. Fortunately, grace to the license, such improvements can be made at a later date by any contributor.
Still, the Wiki loves Earth 2014 contest didn't end: is still ongoing in a few other countries and will conclude with an international contest. Best of luck to all participants! Have good photos and all of us will win (including myself as an ordinary Wikipedia user).
