Halo 4 Theater Mode Effects

Yh I was just looking through some images of halo 4 when I noticed that there were some multiplayer and campaign screenshots that had some kind of camera focus effect on. Ive scoured the web to see if anyone knew hw to use this effect but to my disappointment there was nothing. Now I thought this would be a cool effect to have on theater mode but I was just wondering if anyone else thought the same and would be in favor of such an effect in halo’s theater mode.

Here are links to some images I found with the effect im talking about:
