Can’t seem to get something to synth right? Curious about what lens is best? Ask your fellow Photosynthers here.

My projects all turn out like several pics instead of one continues pic. What am I doing wrong?

Hi there, Big Mike, 

It sounds to me as though you intended to upload panoramas, but instead chose to upload your photos as a photosynth. 

Panoramas have been around for ages and really need for the camera to not change position in latitude, longitude, or altitude while it pivots around the camera lens to look at different things in order for the panorama to turn out clean. The more a camera moves side to side or forward or backward or up or down between shots, the more stitching errors there will be in a panorama, because panorama stitching is just 2D stitching. 

In order to upload panoramas to the Photosynth website, have the option to use one of three tools: 
1: Microsoft ICE: http://bit.ly/microsoftice
2: Panorama uploading plugin for Photoshop for Windows: http://bit.ly/pstops
3: Photosynth mobile panorama apps: http://bit.ly/photosynthforios

A photosynth has similarities to panoramas, but with one very important technical advance: it does stitching in 3D. This means that by tracking individual details in the photos, Photosynth can calculate how far away from each other the details are, as long as they stay still and you have taken photos specifically for 3D reconstruction.

The main differences are: 
:1: In a single panorama, the most 3D that it will ever be is a hollow sphere. In a photosynth, the 3D geometry is only limited by your photos.

:2: In a single panorama, you are confined to a single position. In a photosynth, you are free to move about and take people on a tour.

Here are a few example Photosynth point clouds to show you what I mean:

The only way to create photosynths is the Windows app: http://photosynth.net/create.aspx

If you would like a deeper explanation of shooting for 3D reconstruction, I have written more at http://bit.ly/sinkorsynth

In looking to the future, panoramas are not things that are opposed to photosynths, but rather something that will be linked to photosynths, just as individual photos currently are, but we are not there yet. If you want to follow news on that front, I've collected news links about Microsoft's upcoming Read/Write World project here: http://bit.ly/readwriteworld

Cheers, and let me know if you want anything explained in more detail.
