What about taking the question outside the predictable genres?
Is the heroic vision of the landscape an example of the male gaze? What are its alternatives?
Is there a male gaze in architectural photography, and what would it be opposed to?
How about still life or commercial product photography, which is all about desire, acquisition, possession, power, and other potentially gendered categories?
I think the interesting way to approach this would be to think about what qualities gender the gaze, and then "test" the theory against kinds of photography that aren't about sexuality in any obvious way.
