What is Photosynth?

• Photosynth is a software application that
  analyzes digital photographs to build a
  three-dimensional models.

How does it work?

• Step 1
• Software analyzes multiple photographs taken of
  the same area.
• Each photograph is processed using an interest
  point detection.
• An algorithm detects similarities between points
  and, essentially, connects the dots.

• Step 2
• The next step is to create the 3D model, which is
  done with a Photosynth viewer.
• The viewer is free to download
• The viewer is stored on the users computer, but
  the photos are stored with on a Microsoft server.

Features

• Zoom in and out of photos
• Maneuver through a scene to see photos at
  different angles
• Send photos

Limitations?

• The maximum amount of space Microsoft provides is
  20GB.
• Which equates to approximately 60 synths of
  150-200 photos each.
• Also, you cant add photos, they all need to be
  uploaded at once for a project, Microsoft is
  working on this complaint though.

More Limitations?

• Takes practice to get the right shots
• Only runs on XP and Vista
• Lastly, to get a really good synth, a lot of
  pictures need to be taken.

Applications

• Creative way for consumers to store, and organize
  photos.
• It is also planned to be a back end programming
  tool for Virtual Earths.
