I think the original wording of the subject is stereotyped and when that happens, there is bound to be counter-arguments.
It's like when someone says an expensive camera lens takes better pictures than a kit lens.
Then we will hear the over-used argument "Even a pro can take better pictures with a point and shoot compared to a newbie with L lenses. It's the photographer, not the camera." This is an unfair statement cos you are comparing apples to oranges. (What if both are pros with equal standards?) And we don't often see people who make that statement use kit lenses or point-and-shoots if they have a choice to use their $2k lens! What should be said is that expensive lenses are better optically and in almost every aspect where quality is concered, but the final image is more than just equipment.
Maybe for this thread, it's better to phrase the subject as "Men tend to be more interested in photogrpahy and there are more females as subjects". If that's the case, I must surely agree with it 100%. You can't deny that certain professions, hobbies and interests attract more men, and others have more women. Soccer, cricket, cars, electronic gadgets, photography are some egs for men. For women, nursing, baking, shopping, human resource work are other egs.
As for models... I have a simple theory. It's easier for women to LOOK good than for men. For women, if you are short, people say you are a petite cutie-pie. If you are tall, they gawk at you and say "HOT GAL! U can be a model!" For guys, if you are short, sorry man... Unless you have killer looks, eg Tom Cruise.
For women, don't underestimate the power of makeups and hair styling. We have seen how an ordinary face can be transformed from a plain Jane to an attractive one. Guys? How much make up can u put? Mascara? No way! Hair? Limited styles u can do compared to women.
Body wise... Women can easily starve and diet themselves. When they look thin, people look at them in admiration. Guys? If u are thin, u'll be better off wearing layers of clothing to hide the sticking bones! Women if they are fair, men will gawk and go "Wow!" Like a well-preserved treaure. Men who are fair... Oh my... U look weak. Women who are tanned -- Wow, she's a sporty babe!
Assets... Women who are lucky to be well-endowed (genetics -- nothing much for u to control unless u are rich enough to pay for silicons)... What can I say. half the battle is won. Flaunt them! (Nevermind if the face is quite average-looking.) Strobes will go off like crazy. Men? U wanna show off your assets... Sure... Proper diet, 4-5x/wk in the gym, get that 6-pack abs, bulging biceps, huge pecs then we can talk. It's a lot of hard work. Women don't have to go thru all that sweat and pain. Unless of cos they are body-builders.
So no surprises we hardly find any male models in CS. And no surprises too that newbies pay female wannabe models to pose in awkward, unflattering positions whose final images are junk or probably will be more suitable for mere ogling.
Next time u identify those images, bear in mind what I mention in the above statements. There might be some truths in them!
