How do I make this effect for a Halo 3 screenshot?

[j05hthebear]

I take pictures quite often and have wanted to know how to make the "Äpòçâlýptíç" effect by Air Force Hero at http://www.bungie.net/Online/Halo3UserContentDetails.aspx?h3fileid=71179312
some of my screenshots are here http://www.bungie.net/stats/Halo3/FileShare.aspx?gamertag=BEARP0CALYPSE

Go to

Blackout the map < Then put some screen effects like Old Timey<Then use up your plasma pistol/Plasma rifle<Then when it overheats

it'll look cool
