See extract from the rules, below:
Important. We reject photos of low esthetic qualities (bad angle, included window reflections, pictured just a part of an aircraft, out of focus or similar) and photos picturing an aircraft far in the distance. Spend time finding the right light and angle, never shoot from behind a window, the shadow side of an aircraft, always hold the camera straight (in a straight (90 degree) angle to the ground) etc. Since we added the "Tail and Winglets" and the "Nose Close-ups" sections, we have received a large amount of such photos. Please refrain from sending in such photos just to get them added into those categories. We will reject unmotivated close-ups. The best views are always clear shot of the entire aircraft even though we don't have a special section for such.
