Free photo tool: HD View, the camera for the web! Gigapixel panorama is AWESOME!
Overview
Build Gigapixel panoramas on your website! This is amazing, and I definitely see the “find this item” kind of contests if you hide a small image of a number or something in the picture!
You will need to use the Imagine Composite Editor (ICE) see my blog for more information at: https://bit.ly/photostitching
The information on HDView can be found at: https://research.microsoft.com/en-us/um/redmond/groups/ivm/hdview/, seriously this is fun and if you like to take a lot of pictures, something that is worthwhile.
