I am currently creating a service called PanoPanda.
This service allows professional photographers and anybody with a modern smartphone that has panoramic photo ability to share the high resolution images in their full glory. Up until now there was no other website dedicated to sharing large scale photos and that would work in any browser including mobile.
The website will be free for the first 100 users, after that a few options will be launched to accommodate a wide range of photographers and agencies.
When an large scale image is uploaded from a phone or from a computer it goes through a process that will split the image up in small tiles that are then put together depending on the zoom level that you are viewing the image with. This allows browsing the photo in superb detail without compromising quality or the vast size of it. You can view an example here: http://panopanda.co/msurguy/38
You can try the site right now, browse through the panoramas featured on the home page or upload your own high resolution images. The photographers keep the copyright of their photos so that their work is not compromised.
Please let me know what you think about this service. Would you or somebody you know use it? How much should I charge for it when I get some traction?
