Shooting Technique
Photoscan, Bundler, and Microsoft’s Photosynth all use a similar algorithm for solving large collections of images. Here are some links with more details:
Photosynth Help, which includes the
The Agisoft Photoscan manual also has good information on shooting images.
The Bundler FAQ has a set of recommendations for shooting images to be solved. These are summarized here:
Each point in the scene needs to be visible in at least 3 images
When walking around an object, you should take photos at least every 15 degrees
Overlap images by 35-50%
Lock exposure and shutter speed, so that all photographs have a matched exposure
Use a small aperture, like F/22, to keep the whole image in focus
Before moving from one place to the next, shoot high and low photos
Limit the amount of focal length (zooming) changes
As noted previously , we typically recommend a fixed lens of 28-35mm focal length to minimize distortion effects in the image.

Panorama first, then move around
Make sure all photos are right side up before transferring
Shoot for highlights — make sure that you have original images shot from the camera angles you plan to shoot the actual take from, as the image quality is best when viewed from the same angle’,
