I agree with Bob, photos don't always tell the whole story. Lighting, camera angle, backdrop, etc can all affect the picture drastically and accent various features of the flower positively or negatively.
Regarding judging of such flowers, the ability of the team involved will always range depending on the judges strengths and weaknesses. As a judge, while I agree with many awards that are, like you say, pretty obvious there are others that are a bit more marginal. Flowers in the low HCC range are of particular concern and also flowers at the cusp of AM/FCC are limited due to reticience to stick your neck out.
No matter what judges determine, there are always people that feel they were wronged or overlooked in some manner. I, for one, am a bit more selective and refuse to award mediocrity but everyone has an opinion and it's a team affair. It is amazing how often people are surprised that their plant was not awarded even when it was nominated and reviewed for awards.
Databases like AQPlus and OrchidWiz have made it quite simple to check prior award information, but nothing compares to experience and seeing a lot of flowers, following breeding trends, and having the curiosity to constantly educate yourself.
