Some really great information here thanks!
I also agree, whats the point of having a set built if your only going to blur that background, or going to far off foreign locales to capture that feel and look in the shot. Shallow DOF is great for indie "because" we dont have that kind of budget though, I wont argue that at all. But sometimes I see short films that use that technique in almost every single shot, even on some higher budget short films. Shallow DOF must be used sparingly for extreme purposes in my opinion (Yes just my opinion, dont get mad :P ).
Same thing with shaky cam, I wont even get into that rant here hahaha!
PS: Lawrence of Arabia is timeless, and is masterfully shot.
