So here I am, practicing. On brick walls. To find out how exactly the plane of focus can be influenced by tilting the lens, and by choosing the correct focusing distance.
This is the one where I wanted as much in focus as possible. So tilted the lens plane towards the wall. The full 8 degrees tilt. And then moved the camera to get things sharp.
And here you see the lens was tilted AWAY from the wall plane. You see that only a very small part is in focus. The rest gets a creamy out of focus look.
Now this is good to know. For example for taking portraits in distracting circumstances. More to follow!
