Here's a picture that I figure should do well in several competition categories. It did OK in Nature and Pictorial at the local club.
Yet when entered in a regional competition, the judge ruled it out saying "It looks like something was done to the wings", i.e. Photoshopping outside the rules. That's a Catch-22. The wing detail popped out after I did just the normal (allowed by the rules) amount of Photoshop sharpening. I sharpened the picture as a whole. The startling translucent effect is because the bird in flight is actually shot from above -- a very unusual angle -- with the afternoon sun hitting the wings from side-on. What am I supposed to do, put all that in the title?!
