Getting back to photography, when I look at photos on the web, I think women on average have more interesting photos that connect. I believe this comes from their natural affinity of relations with people while men tend to get caught up in technique rather than feeling. Women also tend to focus on people shots leaving landscapes to the men. Again, for the same reason I mentioned.
What do you see between men and women's photography?
This is complicated, and my feelings on this kind of go against what I have stated somewhat. Also, I am looking at this professionally, insofar as what female professionals shoot compared to male professionals, not the average hobbyist.
My wife is a food photographer, which has nothing to do with people. However, she is very determined and tough as nails when it comes to negotiating. I would not want to be on the opposite side of a negotiation with her. On top of that, it is a commercial field of photography more dependent on B2B marketing then B2C. Overall, I, and my wife, think the negotiating aspect of commercial photography (having the guts to ask for those high prices) and the B2B marketing aspect is less geared to women than men. My wife often gets on other women to get more on the ball with negotiating and just picking up the phone and calling someone, which many women seem to have trouble with. Now many male photographers I talk with have issues with cold calling too, sales and just reaching out to people. However, I think the very nature that boys are expected to ask a girl on a date, and most girls never deal with this very hard to get over adolescence experience filled with denials, holds them back in B2B dealings.
I think back to when I was a teenager and I was super shy. Every girlfriend I had asked me out aside from my wife (so I guess I picked the right one

). So I was never really used to dealing with denials in sales. I just had an intense desire to be a professional so much so, I forced myself to get over it. But to get to the point of being able to pick up the phone and not let a denial bother you mentally took a while. I think this is just something young men have an edge on just do to dating norms.
The real issue is that with B2B marketing there is a very small number of people you market to. For me I have a list of 5000, which sounds big, but a wedding photographer goes after an entire metro area. 5000 contacts is a decent amount to manage and being able to just pick up the phone and call makes a boat load of difference. I, and my wife, have great clients gotten from just making a call to someone who had no reason at all to talk to us.
In addition to that, commercial photography, especially those that fall under the still life genre, are much more technical and more applicable to people who are gear heads. Going back to the study I listed, men tend to be more interested in things, so it just make sense more technical fields tend to be more male dominated. Food photography certainly has it's technical aspects, but not nearly as much as architectural photography. So, although men outnumber women in food photography, men really out number women in architectural photography. I could rattle off a dozen competitors of mine who are men; it takes me a while to think of the few women I bid against. Not say they are less good, just less of them. Film production is even worse, and I specifically talking about the gaffers, techs and grips, not the DPs here. I have a very progressive feminist female assistant who feels film guys are constantly talking gear with her to test her knowledge just because she is a woman. I tend to disagree and think it's just a bunch of gear-heads being gear-heads. (Film people really are super duper gear centric; even for someone as technical as I, I find it baffling how someone could talk nothing but gear all day. Images need to have feeling, but I guess that is what the DP is for, not the gaffers and grips.) So there is this too.
With all this though, there is also the real fact that many commercial photographers don't like hiring female assistants, so they get less exposure to the industry. It's sexist, but not for the reasons you are thinking. Women are not as strong as men, and when you are a commercial photographer showing up with 500 lb of gear, the strength of your assistants make a difference. This is a real (perceived at least) issue with photographers, and the worse offenders are actually other women. I have tried to recommend female assistants to other female photographers and have been turned down. The reason is always, "I'm a woman and I would rather have a man to carry the gear then another woman who may not be able to." Makes sense, for location shoots, and I can not really argue that, but it does have the effect of less women in the commercial side of things.
For studio shoots, I consider this absolute total bull shit since everything is pretty much already there and studio shoot tend to be less intense that location shoots.
(Typically, I usually have no issue with a female assistant and could care less. I am a 210 lb man in very good shape and if she cant lift something, I should be able to. If I cant, then I should not have it. The only time I can really think of when I choose to hire a man over a woman was when I shooting in the 5th story of a 5-story walk-up on West Broadway. In NYC, for all of my shoots, I unload and then park somewhere. It takes about 20 minutes to park, which means by the time I get back all the gear will have been brought to the location. I just could not bring my first assistant, Amanda, to carry 500 lb. of gear up 4 flights of stairs by herself, so I hired Kelvin. And yes, we always comment on Kelvin's name since he is a photographer. Other then this one time, I cant think of any times I specifically choose a male assistant over a female one.)
