2. Presentation
Photosynth is a powerful set of tools for capturing and viewing the
world in 3D. You can share your creations with your friends on
Facebook , publish them to Bing, or embed them in your own
blog or Web site.
It offers two styles for creating immersive 3D experiences:
panoramas and synths. Also it is free, even for commercial use

3. Advantages
- Publishing Panoramas to Photosynth
Users of Microsoft Research's popular and free panoramic stitcher, image composite
editor, can upload their beautiful creations to Photosynth and share them with
friends and enthusiasts worldwide. Here's an example:

It offers high-resolution panoramas. Every last stitched pixel is uploaded, and
through the power of Deep Zoom your viewers can smoothly zoom to the details
whether you've got a 20 megapixel pano shot on a point-and-shoot, or a 10
gigapixel monstershot with your DSLR on the latest robotic head.

4. - Mobile Panoramas
Capture, upload, share, and view Photosynth panoramas wherever you go with
the Photosynth app for Windows Phone and iOS.
These panoramas can be created wherever you carry your phone. Capture
Strange incidents at local businesses, incredible vertical drops in the
Norwegian fjords, or whatever places or events inspire you. From just a few
stitched photos up to full spherical panoramas, the Photosynth app allows you to
take Photosynth on the go and use it anytime.

5. Drawbacks
Privacy in Photosynth
If you upload a panorama or a synth and accept all the default choices, your content
will be public. Everyone on the Internet will be able to find it and view it.
Limits on Unlisted Synths and Panos
Photosynth is a free service. You are permitted 20GB of storage for public content,
and 1GB for unlisted content. Users are also restricted in the number of views
their unlisted synths can attract.

6. Conclusion
The first style, and the one that still uniquely defines the product, is what we call a
“synth”. A synth is a collection of overlapping photographs that have been
automatically reconstructed into a 3D model of the space.
The synthing process solves the same problem our brains are confronted by when
we look at the world: the slight differences between what our left and right
eyes see gives us cues about how far away different parts of the scene are.
In a similar way, the differences between two photos taken from nearby positions
can be analyzed to determine which parts of the scene are close, and
which are further away.
