Hello all --
Another newbie question on lens tilt. I have figured out how to raise the camera about six feet in the air (http://www.largeformatphotography.in...d.php?t=65362). If I keep the camera bed level, using the Merklinger hinge rule the angle should be 5 degrees (angle = 5*focal length/J). If the camera is 6 feet, then J=6 and 5*6/6=5. All is good. And yes, I realize I need to focus a bit above the ground so I have depth of field above and below the plane of sharp focus.
But what happens if I tilt the camera down to encompass more of the foreground? Let's say for example that I tilt the camera down 5 degrees. Now the back and lens board are tilted at the same angle and so are parallel, and the plane of sharp focus is also parallel. If I tilt the back to vertical? This is the same as simply tilting the lens, no? Or maybe I should just use fall for the lens??
I'm getting myself terribly confused.
