This started out as a very interesting discussion and has quickly deteriorated. Let's get back on track eh!
The reason that quotes like "Beauty is in the eye of the beholder" have been around so long and are well known is because they're true. Beauty is not some Hollywood standard but means something different to everyone. As a portrait photographer, ie. not models, it is my job to bring out the beauty and/or character in every subject that crosses my camera. Do I succeed every time? Probably not. But...
Quite a few years ago, I 'took' a photograph of a friendly old man in Nova Scotia along with his two oxen. A friend of mine and I found them in the front yard of this humble country home on a backroad off a backroad. He came out to offer his help and bring the oxen closer for us to photograph them. You could see the pride in his face of his 'babies'. He crouched out of the way as to not be included in the photo, but I had my wide-angles lens on and captured him kneeling before these huge beasts, looking up at them.
A few weeks later, after having the film processed (remember, this was quite a few years ago), I sent him a copy to thank him for his assistance. About 6 weeks later, I received a letter from his son. Shortly after the portrait was taken, he had a complication with an operation and passed away. The letter went on to say that this was the ONLY photograph they ever had of their father (he was easily in his 60s) and, quote, 'if any one picture could sum up his life, this was it'. He had raised these oxen since calves and they were his pride and joy... all captured in 1/30 sec (or there about's.. no metadata to check!)
My point is that YOU may not see the character or beauty in the portrait, but someone who knows the person will. I believe that Karsh summed it up quite well in that quote. Even if you photographed 1000 beautiful women, I'm sure only a handful would stand out over the rest. This happens when you capture that moment.
It is not up to us to decide what is beautiful or not... it is to capture, as much as possible, the essence of our subject. You can quote me on that!
