It would be great to have the app for the iPad with the ability to transfer photos from iPhone to the iPad.  This will be great for letting others view the photo on Photosynth on the iPad and also makes it easier to edit. Was looking for a new place and taking photos, but couldnt appreciate the full effect on the iphone due to its screen size.

When are you planning the ability to view Synths ( as opposed to panoramas) in your iOS or HTML viewers? Are there any plans to fix the iSynth app which does not work on any current release iOS device and frankly should not even be made available for download?

Please do consider allowing photosynth to be installed on thenipad1 to allow users to see the pics created on the iPhone on their iPads

@squareflips, you seem to be asking mainly about panoramas taken with the iPhone app being viewable on the iPad, if I'm understanding you correctly. 

Any panorama that you've taken on the iPhone and uploaded to your account, should be able to have its location, title, etc. edited on your iPad, if you've installed the iPhone app on your iPad and signed into your account. 


@Kattapuram, you can install Photosynth's iPhone app on your iPad, if you like. Also, you can view any panorama on, using Safari on your iPad, so viewing others' panoramas should be quite simple for you, already.

@ReefQuest, you're not likely to get a timeframe for viewing synths in the HTML or iOS viewer announced ahead of that functionality's release. 

I believe that work is going forward on that via the Read/Write World project. 
(See for announcements from 2011.)

The iSynth app is not (and never was) an app created by the Photosynth team, but was rather the product of a Live Labs summer intern, Greg Pascale. He did join the Photosynth team for a year or so, but has since left Microsoft to work with Gary Flake at 

I believe that iSynth was functioning correctly until Photosynth transferred their imagery from LimeLight Networks (where it had been since their Live Labs days in 2008) to Windows Azure earlier this year.

I think that if Greg updated his app to look for the new URLs, it would work again.
Ask him here:

Can't believe this wont work on an iPad.

I know Mac and Windows are competitors but not being able to view synths on an iPad is a massive mistake in my eyes.

@dtymt, Can you give me a link to what you are wanting to view on an iPad?

Every panorama on should be viewable on both Mobile Safari on the iPad as well as the Photosynth iPhone app. 

Every photosynth on is a different format of imagery (i.e. not a simple cube map with a Deep Zoom Image for each face of the cube, but rather up to around 2,000 different Deep Zoom Images arranged in 3D space as well as a corresponding 3D point cloud model of their shared contents).

As I mentioned above, Greg Pascale's iSynth app used to load the point cloud and the camera positions and even thumbnails of each photo in the synth to give you a reasonable experience of viewing a photosynth on an iPhone. 

I used to use it all the time when I used an iPhone 3GS and he could updated it to load full resolution images and draw more of the point cloud when the virtual camera moves, now that iPhones and iPads have much better RAM, GPUs, and CPUs in them.

Being able to view panoramas but not photosynths is nothing to do with Microsoft and Apple being competitors. Rather, it has to do with Photosynth's team not making Microsoft any money, but taking money to run. Because of this, they do not have much money and therefore cannot hire many programmers to work for them. 

It is a simple fact of needing some programmer out there to build a Photosynth viewer in a graphics technology that will run on iOS, Android, Windows Phone, Windows RT, and XBOX. 

Photosynth's first photosynth viewers were all written in Direct3D. (You can still use this whenever you are on Windows, using Internet Explorer or an old version of Firefox 3, and click the "View this Photosynth in the Direct3D Viewer" link in the lower left corner of a photosynth's 'View' page.

After that (before the smartphone revolution) Microsoft was trying to encourage web developers to use Silverlight to write better web apps, since Silverlight was built to run on Mac OSX just as well as Windows. That's why, just a few months after Photosynth's release on the web, Photosynth reprogrammed their viewer on their website to use Silverlight (which couldn't yet use your computer's graphics card and so couldn't do as good of graphics as the Direct3D viewer). 

Apple outlawed all web browser plugins on iPhone and other iPad devices. This is why any webpage needing Java, Flash, Silverlight, etc. doesn't work on an iPad or iPhone. 

When Google released Android, they allowed Flash at first. 

When Microsoft released Windows Phone in 2010 they didn't support Flash either. 

Adobe later announced that they were going to stop programming Flash for all video game consoles and mobile devices.

So the reason that the Silverlight viewer doesn't work on iOS, Android, or Windows Phone is that Microsoft decided that trying to push their own technology (Silverlight) on the web wasn't a good strategy, since so many different types of devices access the web with decent resolution nowadays and an increasing number of them aren't running Microsoft operating systems, which makes more and more work for Microsoft if they were going to try to support every device type. 

Instead, Microsoft has changed directions to holding web standards technologies (which are appropriate for the web and are decided by a combination of representatives from all companies) to higher standards of performance and reliability.
Meanwhile, Microsoft has switched focus to using native code (C, C++, DirectX/OpenGL) which runs on all operating systems for building local apps. 

A photosynth viewer needs to be built in CSS:3D, HTML5 Canvas, or WebGL before we can view synths in any browser.
