As an amateur photographer, I have always kept my eyes open for new tools to help me search, sort, filter, and view my own photos. Microsoft Pivot (a cool new technology that lets you easily view, search, and filter data using deep zoom) seemed like a natural and obvious fit for the task.
Therefore, using Microsoft Pivot and the Pauthor open source libraries, I created a tool that helps users create a pivot collection from the photos on their hard drive and supports filtering by all the nifty meta data embedded in those files such as shutter speed, aperture, film speed, and focal length.
