To be fair, at these model shoots, there are photographers and there are GWC, you cannot deny that. As for whether someone is there purely for his/her own photographic aspiration, or to snap pictures for his 'self gratification' purpose, only that person knows.
That said, the pictures that XX showed, do support her point, although she is biased in her views.
Just look at all those people shooting at SIN, and you'd get the pictures. I seriously don't think that all are there to practice photography. Just look at the majority of the threads that featured pics from SIN, juts how many actually are pics of cars? And then there's so many 'nosebleed like crazy' type of comments, just how many are looking at the pics of these scantily clad models and think about composition, lighting, ISO, exposure, aperture, etc?
This is not jut the views of XX, my wife thinks like her too. She labelled the photographers at SIN as desperate and losers in life privately, and I'm sure many girls think likewise, but just don't comment out loud like the motor mouth XX.
We guys know best what we guys are made up of : we love those pics simply because many of these babes are hot, and they get us hot in our pants as well. Just admit it guys, there's really no need to justify.
