I have photographed many compositions that only required leveling of the camera, or downward/upward pointing. Sometimes I need a bit of front tilt, and back slide. There have been a few times where I've had to tilt the front and rear standards forward to make them parallel with each other. The odd time I've used front swing... I can't even remember the last time I used both front and rear swing at the same time... Then there are the times when the moment was fleeting, and only had time to set up, stick wrong lens on, focus, insert, holder, and take photo... and I've still been pleased with the results
