I've long been trying to figure out how to get Master Chief to promote HD View. Lucky for me, Torgeir Holm has done it using the screen shot feature on Bungie.net. He uploaded 33 screen shots of a 360 environment and stitched them in PTGui (image below), then using Photoshop added 13 more zoom-in screen shots for the more interesting details.
Bungie stores a rolling buffer of a user's last 40 screen shots. For the time being, you can still see some of the original screenshots here: http://www.bungie.net/stats/halo3/screenshots.aspx?page=0&gamertag=Doglet , http://www.bungie.net/stats/halo3/screenshots.aspx?mode=pinned&gamertag=DogletHD View, Halo 3, Games, Gaming, Microsoft Games
