I tried out PhotoZoom on Microsoft Live Labs tonight. I created an album for some of my outdoor photographs taken in Texas. I've loaded only one so far, a shot of Blue Mountain during a storm in the Davis Mountains. PhotoZoom uses the deep zoom technology built into Silverlight allowing a smooth zooming and panning experience on very large photo files. I uploaded the file at nearly the top resolution of my 10.1 megapixel DSLR. PhotoZoom post-processes and stores the file. The photo can be browsed at PhotoZoom, but the site also produces a snippet of HTML to embed within any web page. I had originally posted this photo on my flickr site with a much smaller resolution. Here's what can be done with PhotoZoom:

The deep zoom capability in Silverlight is based on some work done by Microsoft Research called Seadragon. (Seadragon Software was acquired by Microsoft in early 2006.) They have embedded the technology in Silverlight and have recently released an AJAX control. Seadragon Mobile was also used in the iPhone application that was released this week.
