I dislike them. They foreshorten the body so one looks much like another and you can't get a good look at the girl. Plus upshots project power and I'm dominant not submissive.
Well...there's one good thing about foreshortening. It gives at least a little bit of a sense of depth to an image that's otherwise (often) flat and washed out. I wouldn't care to see two hours of nothing but upshots but a few here and there are nice and some of us are sub (or both). I love to see a nice, thick ass from below.
When I want to enjoy watching people fuck, the thought of..."hhmmm I wonder how this would look if I were lying down face first on the rug" never approaches my mind.
It's not a sub or dom thing with me either. It's more of a, hey there's 2 people having hot sex..lets try to capture the entire image(sweaty hair bouncing, cut O face's, titties, bum,etc..) rather than watching from a footcam
I think it's hot, especially when the camera is angled diagonally. You get to see penetration and the facial reactions. Plus, the depth of field at this angle doesn't distort.
I don't mind them in moderation . Unfortunately we're dealing with a large number of camaramen with very limited skill and imagination, who are only able to shoot in this particular way.
I don't mind them when used VERY sparingly, but if they're more than a quick and rare change of perspective they're lame.
They qualify as a trick shot, and trick shots are supposed to be very much the exception for a reason.
Somewhat off-topic, I don't care much for gyno-closeups (penetration closeups) either. I really hate it when we get more than a few seconds of genital closeups.
Then there's the framing problem practically every cameraman in the world has. I see it constantly, where a significant part of a girl's body is left out of frame so we can make sure we see ALL of the guy's ass. That's just stupid. There's some overlap with the gyno-closeups here too, where some cameramen seem to think the camera should treat the guy's hip area as equal in importance to the girls'. That's just dumb; get his pecker in there, maybe a bit of his abdomen, but use the rest of the frame for the girl.
