Carried in wallets and displayed in homes, photographs are a common, but often an overlooked feature of modern life. And, with the advent of digital technology many believe that the so called 'wet chemistry' behind old fashioned photography is a thing of the past - but is it?

The Chemistry of Photography endeavours to unravel the mysteries of picture taking and reflects on the diversity and complexity of the science. It gives readers an insight into the chemistry needed to generate pictures, spanning all mediums including still and motion picture as well as digital imaging.

Beginning with the components of conventional photography such as films and papers, the book also looks at light capture and amplification, negative films, processing solutions, colour transparencies, the chemistry of colour and motion picture films. The book concludes with a discussion of digital technology and new innovations in photography.

This fascinating book will appeal to scientists and those with a general interest in both the new and the old science behind photography.

Patent on Media Interestingness - A new class of metrics !

I suddenly realized that photo-sharing sites such as Ipernity may be (some day) infringing on a flickr patent! You'll have to read to read the details in the application, but in its method of claims includes all "groups" and "taggings" ..

What is Interestingness?

Interestingness is what Flickr calls the criteria used for selecting which photos are shown in Explore. All photos are given an Interestingness "score" that can also be used to sort any image search on Flickr. The top 500 photos ranked by Interestingness are shown in Explore. Interestingness rankings are calculated automatically by a secret computer algorithm. The algorithm is often referred to by name as the Interestingness algorithm. Although the algorithm is secret, Flickr has stated that many factors go into calculating Interestingness including: a photo's tags, how many groups the photo is in, views, favorites, where click-throughs are coming from, who comments on a photo and when, and more. The velocity of any of those components is a key factor. For example, getting 20 comments in an hour counts much higher than getting 20 comments in a week.

Does Flickr really have a patent on Interestingness?

Interestingness ranking of media objects

Abstract

Media objects, such as images or soundtracks, may be ranked according to a new class of metrics known as "interestingness." These rankings may be based at least in part on the quantity of user-entered metadata concerning the media object, the number of users who have assigned metadata to the media object, access patterns related to the media object, and/or a lapse of time related to the media object.
