As was the rule last year. Any PHYSICAL CHANGE to the photo, be it a rouge sign, a small ding, or a color match being changed would be a disqualification. Only actions like contrast, brightness, and levels should be used. Though, theorhetically, you should (if taking a good picture) have 99% of that done correctly WHEN you snap the photo.
agree 100%
as long as we are on the subject of judges....if there are any possible spots open, id be willing to be a judge
