Image Effects/Depth of Field (Lens Blur, Scatter, DX11
I've experienced the rift for literally 3 minutes. I can't recall if depth of field blurring occurs naturally enough to not warrant adding Depth of field effects in Unity 4. I did try without the rift, but only the right view was effected/affected (can't remember which effect/affect to use)

- As far as I've seen, you can still use most post processing image effects, but you'll have to apply them to both left and right cameras. If it's an image effect that potentially results in differing images (other than the stereo separation, that is), you might need to modify your image effect to sync up somehow.
Having said this, there's a couple stock image effects I never got working right (even in one eye) and this is probably because of something more fundamental related to the modified projection matrix.
Don't have a Rift yet, not sure whether depth of field still applies as a useful effect. It's probably in the same category as intentional chromatic aberration, lens flares... they tend not to make sense when you're supposed to "be there" in the VR world. - Some full screen effects don't work well in the Rift, especially effects that work different in the center of screen and edges. For example I played around with the chromatic aberration filter and even though I made the effect really extreme and noticeable on the standard monitor, in the Rift it just came across as a weird blur.
- Image effects should work. Just be sure to apply them to both cameras.
- I'm having trouble using image effects that rely on the z-buffer (global fog, for example). The fog that's generated isn't lined up with the lens correction (if I turn off lens correction, it lines up fine). Is it that the lens correction isn't warping the z-buffer as well?
- Yes, there is a solution to this, see here:
