I have just got back from the stunning Stellenbosch near Cape Town, where I took lots of pictures, some of which are on my Flickr page.
One of the photos was the biggest panorama I have ever taken. It was made of 10 D800 photos stitched together in Photoshop and it measures 27,246×5,874 which, for those without calculators or the Rain man like ability to multiply big numbers is equal to 160 Megapixels.
Years ago I used to use Zoomify but that is no longer compatible with my Mac so I started looking for other options. This is a good blog post and came up with a couple of options. The option of using Google+ was out because the image is to big to upload to Google.
Zoom.it sounds quite straight forward so I uploaded the file to some webspace and then typed the url into zoom.it
