I have installed photosynth in my iphone 4 but the resolution is too low.
Is possible to modify the resolution?

Tks

Hunter81, I don't believe that it is possible to change the resolution, however I am not on the Photosynth team, so you may want to wait for an answer from them.

I could be wrong, but I believe that the reason that the resolution of each still shot captured to be stitched with the Photosynth app is low is because it is using the iPhone's camera in video mode, rather than still photography mode. I believe that this is necessary to do the realtime tracking of the viewfinder against the panorama shot thus far.

I am also not sure what the memory limits are for iPhones stitching together higher resolution stills or how the image quality differs between iPhone 3GS, iPhone 4, iPad 2 and iPod Touch 4. Presumably, the app uses the same resolution stills on any of those devices, but I might be wrong about that as well.

I agree that it would be excellent to have devices with higher resolution sensors to be able to capture better images. How do other panorama apps compare?

The end result is much lower than the potential of the phone.
In other apps is possible to modify the resolution but i don't like how they stitch. I think that photosynth is the biggest app for iphone 4.
I know there is a file ".plist" modifiable that allows to change de base resolution but i don't know which.

Sorry for my English.

i would like to know more about that plist file, also

I don't have any insight into the ".plist" file. 

I think that this conversation I recorded from Twitter does shed some light on the matter of limited resolution, however: http://bit.ly/psmpr
Note that David Gedye says that writing full resolution photos to your mobile device's flash memory while still smoothly tracking the incoming camera feed is the real limiting factor. 

I'm not sure if that can be fixed with more RAM or if something else in mobile devices' architecture needs to change to accommodate the coming wave of augmented reality apps.
