A community member has dug deep into Forza 3’s latest update file (which previously had displayed all the DLC cars for the future) to reveal more goodies:
future updates could see players being able to enter ForzaVista mode at any point during free roam. Not only that but the photo mode will include higher resolution photos dependent on where you decide to take them. That’s not all for photo mode however as more blur samples are said to be included also enabling players to adjust depth of field.
That being said there is no confirmation of these features actually being added, but judging by the fact that the info was in the development build you can bet that they will come about.
