http://photosynth.net/view.aspx?cid=d29445b3-9a9a-4030-95b3-ac6313b84964 is my working project...no comments about the decor please! - probs the slideshow only picks up one highlight (the  framed kaftans) and none of the other 5... and it dives at about 45 deg for some reason, any advice please?
this is copied from another area where it didn't receive a reply - since then I've tried juggling the highlights but still no solution...

Hi there, theMink,

Photosynths are different from panoramas in that you can change positions (walk over to and around things) and fit a lot more space in a single experience. Because of this, the slideshow mode in a synth is designed to take you on a tour through every photo in a synth in Photosynth's spatial order, completely independent of the highlights. 

If you want to know Photosynth's spatial order, look at your synth in 2D View:

If you want to change the order of the slideshow to the order that you took the photos in, sign into your account and click the [ Edit this Photosynth ] button below your synth. Once you're in the editor, go to the Advanced tab, and select 'By Filename' for Slideshow Order.

The photos which are displayed at an angle are just photos with very weak connections to the rest of the synth. Photosynth tries to determine which way is up for the entire point cloud (and thus all the connected photos) since someone might be looking in any direction when shooting a synth. If you know that you took all your photos right side up and Photosynth is displaying some of them tilted, then use the synth editor's Advanced tab to select 'Photo up' instead of 'World Up'.

Always be sure to save when you're done using the editor.

If you don't mind saying, where did you ask this before and get no response? Could you provide a link, please?

A nice example that I just found on Twitter of Photosynth wanting to display the things in the photos right side up, rather than the photos themselves can be found in the first photo in this synth: http://photosynth.net/view.aspx?cid=85edbfda-77c0-426b-8e22-62c5c1fd7452

Hi Nathanael and huge thanks for response. I'm just getting to grips with the differences and sadly excited by them too! i'm a great believer in 'just get stuck in and play about - see what happens' but tend to confuse myself at the same time so having someone outside take a look is extremely useful!

Changing to Photo up sorted the issue - I also get the pt about this being texture related and if there isn't enough info then things can go a bit random..!
still not getting the highlights not being shown - looked at 2D sequence but the highlights aren't in there are they, and they're not being used in the 'show' - bemused!

Just looked now and the one highlight that play is in the 2D line but not the others, why / how could that be? Tried dragging them in but doesn't work...would be useful!

Okay. Apparently I need to work on being more clear.

When Photosynth first launched, there was no panorama support - only synths. Similarly, there was no highlights feature when Photosynth first launched. The original purpose of the slideshow or the 'Play' button was simply to automatically move from one photo to the next until you reach the end of the cluster and loop back to the beginning. 

When highlights were first introduced, there was still no panorama support on the website and highlights only pointed at an entire photo, rather than part of it. The synth slideshow remained identical to how it had functioned from the beginning - it simply plays through all the photos in order of proximity to each other. The highlights only served as a way to bookmark particularly interesting photos and were an alternative for people not willing to wait for the slideshow or who found it difficult to get from one photo to where they wanted to go.

In other words, in synths, the slideshow has never been connected to the highlights. They are two separate ways to explore the synth, just as Overhead View and 2D View are different ways to explore it.

When panoramas launched, highlights got a little upgrade as in panoramas they only made sense if you could select portions of the panorama. This carried back into synths as well, allowing us to select only a portion of a photo, rather than the entire picture.

What about slideshows for panoramas, though? Panoramas aren't like synths where you get to move all around an environment. If you've shot a panorama to be free of stitching errors, you haven't moved the camera lens' position at all, so the slideshow can't be a 'tour' like it would be in a synth. So, in panoramas' case, the Photosynth team made the slideshow follow the highlights since there's nowhere to go in a pano.

In photosynths, tho, the slideshow's purpose is just to tour through every photo in the synth.
