Re: Husband keeps on taking pictures of other women
I am a photographer. It should be quite evident whether he is taking the shots for aesthetic reasons, or some more sinister reasons. It should be evident in the shots.
I'm not very comfortable with "candid" shots like this, but they are perfectly legal. Here is an example:
I once took a shot of young boy sitting cross-legged on a sea wall, deeply engrossed in a comic book. I felt slightly uncomfortable taking this shot, but the scenery (which composed most of the shot), was beautiful and the juxtaposition of the sea, the boats, and this boy oblivious to it all told a story.
That's the key. For someone interested in photography, the shots should be telling a story.
I'm betting that these shots are pretty much full-frame shots of the women. That's not about photography. It seems to me to be some kind of voyeurism.
I think you're well within your rights to demand that he stops. He's also asking to get a whole can of "whoop-ass" opened on him.
