Thanks a lot, Badger, for your efforts!!! I really appreciate that.
However I have to agree with Ulco. The images I saw in your tilt shift thread were mostly shot from quite close. Even if the blur isn't meant to give some realistic effect but more an artistic one, the eyes are used to see DOF blur in certain situations, which is objects quite close to the lens.
Recently I wanted to take a photograph of a nice landscape with some leaves of a tree blurred in the foreground. It just didn't work until I had the leaves millimeters in front of the camera. I could have zoomed in from a certain distance to get that blur. Anyway it wasn't easy.
Now if you take my image: the camera seems to be hundreds of meters away from the ruin. Any additional blur would make this look like a model of a terrain.
So if I were the director or the editor (hey,
I AM the director!!! ), I would rather use some other methods to focus on the center of the scene if necessary.
Thanks anyway!!
