hi,
I have been in paris and I took some synths with my nokia lumia 710, I was very happy with the result and thought it would be a very good way of showing my friends and family the places I visited but when I got to England and i was going to show a friend the pictures all my synths had gone and I had instead all the ones I had on the internet. I still have all the synths on my camera roll. Does any body know what happened? And is there any way in which I could use the panorama that was saved in my camera roll to make it work on photosynth? thanks

Hi, elrumo,

I was hoping that someone from Microsoft would answer you but it's been over a week now and no answer yet. I think they're all on holiday right now. 

The only reason that I can think of why your panoramas' cube maps would have been deleted from your phone's storage is if you uninstalled Photosynth's mobile pano app from your WinPhone and then reinstalled the app.

If you did uninstall/delete the app, then all of that app's data gets deleted with it and when you reinstall the app from the Windows Phone Store, it can only open what you've uploaded to your account.

The flattened copy of your panorama which were saved to your camera roll would survive an app deletion because they are simply photos in your phone's camera roll (i.e. not saved in the Photosynth app's private storage folder).

There's no way in the mobile app to take one of the flattened/reprojected panoramas from your camera roll and transform it back into a cube map for interactive viewing.

You could try to use the Photoshop to Photosynth.net panorama publishing plugin ( http://bit.ly/pstops ) on Windows to try to transform your flattened pano back into a cube map, but often the resolution towards the north and south poles of your panorama will suffer from having been flattened and sometimes some of the picture information is cropped out (at least this used to be the case, according to Photosynth mobile developer, Denis - a.k.a. SignalToNoise http://photosynth.net/discussion.aspx?cat=c76bfe71-d042-4aec-b49b-b48b67d7be96&dis=41b1db59-b33e-46a8-b641-cd438ffab703 ). 

Alternately, you might have some success finding a panorama viewer for Windows which can reproject a flattened pano back into 3D, although I don't have any suggestions beyond the above. 

I wish that Photosynth's mobile app wrote the EXIF information into its flattened panoramas so that Microsoft Research's excellent HDView panorama viewer could open them correctly, but so far it doesn't.

If you didn't ever delete your Photosynth app between the time that you captured your panoramas and when you got home from vacation, I'm sorry. I don't know what went wrong and have never experienced anything like that with my Samsung WinPhone.

If you didn't delete your Photosynth app (and thus have a reason to believe that your panoramas' cube maps should still be on your phone, even if the app can't see them) you might be able to find some unofficial file explorer for your Windows Phone such as TouchXperience ( http://www.touchxperience.com/applications/summary/22/33.html ). 

I've never used one myself yet and they most definitely aren't supported by Microsoft, so proceed at your own caution. If TouchXperience doesn't work for you, I don't really know of other Windows Phone 7 file explorers, so you should reach out to someone knowledgeable like Rafael Rivera.

The lesson for anyone is: Upload your panoramas to your Photosynth.net account right away + avoid this!

To get a flatenend camera-roll image back onto photosynth.net is easy.

1: Copy the camera-roll image to your PC.
2: Use any drawing program to split your camera-roll panoramic image into two or more parts.
3: Use Microsofts ICE (downloadable from the photosynth page) to reconstruct the image as a "radial" photograph.
4: Once ICE has reconstructed your photograph, simply press the "upload to photosynth" button from within ICE.  Easy, takes all of 10 seconds.

that would not work at all, Jaredhemmings.  Not easy nor takes less than 10 secs at all.  ICE doesn't work with the photos created by photosynth.
