Sadly Photosynth shows real preference for the sky showing around the edges of leaves rather than finding common features on the actual leaves. This would be understandable if the leaves were blowing in the wind, obviously, but today was really quite calm. I can't complain too much because there are really no close ups with the leaves in this synth, but it's definitely a problem that I'd love to find a solution to in the future. This was a rush job between catching buses on my commute home a few days ago, so I'm not too dissapointed. As a side note, tree trunks perform admirably well in Photosynth, happily so winter trees should be a piece of cake. I'll be on the lookout for a good selection of fully synthed leaves, flowers, and other natural objects in my favourites list in the future, if that sort of thing appeals to you.
