After 25+ years of using view cameras, I actually have to think to remember the view is rotated 180 degrees - sometimes I'm surprised when people comment.
Oddly, I have no problem using the viewfinder of an SLR or rangefinder camera, I make the same errors with these as I do with the view cameras.
But the point is that sometimes you need to see both views within the confines of the frame. Although with LF you can use your eyes outside the ground glass, it’s not quite the same as seeing both views within the confines of the frame. So in that way the LF user is almost as restricted as the SLR/Rangefinder user.
