Created a great synth or panorama? Shot some great photos? Showcase some of your best work here.
Could some one give me some pointers have done this twice now but still it is not getting it quite right. There are points that it jumps to a random part of the garden.
Let me know what you think
The order that the photos will play back in is somewhat based on which photos can be connected to which and also slightly randomised (so that if someone has moved very patiently and consistently around a scene to get a good 3D reconstruction, but looking at every single photo in order might be slightly tiresome, a little life is injected into the tour).
If you do not like the default photo order, you can use the fullstop [.] key to move through the photos in the order of the filenames that they had when you uploaded them and use the comma [,] key to step in reverse alphanumeric order.
If you'd like everyone to see your photos in the order in which you shot them, regardless of whether they use the fullstop and comma keys or not, you can edit your synth settings to playback in filename order, rather than the default spatial order, by clicking on the button just below the centre of your synth when you are signed into your account, navigating to the [Advanced] tab, clicking the appropriate option, and saving your changes to your synth.
The only downside to navigating in filename order (via either method) is that in the case of a synth in which not all of the photos have connected (switch to 2D view [~] to see which photos have connected to which), filename order will lead you from the middle of one group to the middle of a completely disconnected group of photos. Whenever this happens, the experience of being in a single 3D environment will be broken as Photosynth will not be able to correctly move the viewer in 3D from the last photo in one group to the next photo in another group, simply fading out and then fading back in, wherever you cross group boundaries.
In a 100 percent synthy synth, however, using filename order can be exactly what you want if you took care to take the photos in a particular order or if you renamed the photos on your computer to be displayed in the correct order.
Alternately, you can simply add highlights for as many of the photos (or parts thereof) as you wish and order the highlights to guide people easily from one important part to another in a guided tour.
As to getting to all the photos matching, you can either retry synthing the photos to see if it randomly connects more of them, retry synthing without the photos that didn't match the first time, or go out and take more photos at intermediate positions between the photos that didn't match and their nearest neighbours, also taking a replacement shot for any shots that were out of focus, overexposed, or were taken with the camera in motion the first time.
If you mainly care about sharing a healthy, but not overly large group of photos that just give people a good look about a place then you are quite close to where you ought to be.
If you care mainly about the 3D reconstruction, try circling all the way around multiple things in addition to walking between them.
For other tips such as having three different shots from three different positions of any target which you wish to see in the pointcloud which are:
1) not more than 25 degrees away from the last photo when moving around the target and
2) not taken from distances so different that the object more than doubles within the frame of the two nearest photos of it and many other useful general rules of thumb, also see the Photosynth Photography Guide, available here: http://photosynth.net/help.aspx#photosynthhelp
