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

have tried using this program only twice now and should refrain from judgement, but am a bit disappointed at this stage.  The problem in both cases is that photosynth uses only a fraction of the pictures I provide.  First attempt was on a chair, and in hindsight I can see that the program might have problems reconciling some angles on this subject.  second, however, was a statue where the reconciliation should not have been at all difficult, yet with the same result.  Am I doing something wrong?

Hello, zilch,

Taking photos for Photosynth does take a little learning. Here are a few quick tips for you.

- Try to let the object that you're shooting stay still while you move the camera around it. 
(Any time that you use more of a turntable/lazy-susan approach [turning the object while the background remains the same] runs the risk that Photosynth will find all the similarities in the background, which is standing still compared to the foreground object which is moving.) Photosynth can only reconstruct whatever stays still in the scene so either let the statue stay still while you walk around it from different angles or be sure that the backdrop is perfectly blank. (In your case you had the black cloth which the statue was standing on and Photosynth was tracking the wrinkles in the cloth instead of the statue as it turned in some cases.)

- Try shooting your subjects in simple circles first (or as much of a circle as you can walk around them), then follow up with fancier angles, provided that the new angles are close enough in position and angle to one of your other photos, or just take a photo between where you've already stood and your new dramatic angle if they're too different. Essentially you've got to show Photosynth how to get from any one of your photos to the next, using your camera.

I'm not certain if you've read the Photosynth Photography Guide, but it has more detail on things that should work and what probably won't work than I can describe here. Download it from this page: http://photosynth.net/howtosynth.aspx There's also a short video tutorial available there which is quite useful, but the Photography Guide has more detail.

The orbital technique is about the simplest that I can think of for new photosynthers. Try a few at different heights and distances and let me know how it goes.

yes, I see, this is helpful.  No I've not read the guide and will do so now.  Thankyou for the good information.
