Because Photosynth uses photos differently than other photographic processes, it means you’re going to have to shoot your scene or object in a way you may not be used to. Among the things we did lots of times before learning not to: - Not taking enough pictures. Photosynth requires lots of images. With memory card prices going down and sizes going up, go crazy and take more than you think you’ll need. You really want to cover your subject thoroughly. But don’t just shoot random pictures—think about how they’re going to tie together, and how you’ll be navigating through your synth. Be methodical about how you shoot.- Taking pictures that don’t knit together. We repeat this lot, but that’s because it’s so important: each of your pictures should have at least 50% overlap from the previous picture. When you take pictures at drastically different angles Photosynth can’t match them up and you end up with ‘orphans’, pictures that don’t connect to any others. So even though you've taken lots of pictures (because you read the paragraph just above this one), that doesn't mean you should use them all --leave out the ones that won't connect to the others.- Poor choice of subject. Things with extremely complex or repeating patterns don't usually work very well (like a willow tree, for example). Things that are really colorful make great pictures, but not great synths, because Photosynth doesn’t look at color, it looks at texture. Look at the ‘Nice and Synthy’ section of the photosynth.com site, and see what worked. Look at the 2-D view of the pictures and see how they fit together, how many pictures were used, and the angle at which they were taken.
So, let's get synthing!
