I'll try to cover the points made above.
The 700px thing became unenforceable pretty quickly. The next photo contest, I will have a better image uploader that will resize automatically for users.
Selections in the event photography section. I realized my choices would be polarizing. I have a very specific taste in wedding photography, and it's probably a fault of mine. I should have also separated wedding, concert & other into their own categories. It was a tough category.
The next photo contest I do, I will have another 2 people involved and we'll vote. I'm sure all of our tastes will be different.
I have learned a lot in this contest, and I have a better grasp on how to do the next one better. It really is harder than it looks.
The readers of Canon Rumors will be selecting the best image in each category and then I have a panel of people that will select the winner and runners-up.
