"The fascinating field of digital forensics couldn't be more relevant for a journalist, researcher or editor. Specialised analysts can test the authenticity of a photograph: how many times has it been saved? Have additions been made to the original, and if so, in which order? Are parts of the image generated by a computer?
Professor Hany Farid, based at the Department of Computer Science at Dartmouth College in the US, explains that photo forensics refers to mathematical and computational techniques "that seek to determine if a photo has been altered from its time of recording, and how/where the photo was altered.
"This field of study is highly technical, and while some simple analysis can be done without much technical training, most of the forensic techniques require a highly skilled practitioner.""
In this digital age, metering is becoming a lost art. Many new photographers seem to be relying on the back of the camera for metering and correct exposure. Although, as a photographer mastering proper metering techniques is essential for achieving consistent repeatable results.

Lighting 101
Intimidated by the idea of off-camera lighting?
Don't be.
We are pretty much starting from scratch, so no worries. The first posts will be about what kind of gear you will need to do the minimalist strobe thing.
When we are done having our way with your wallet (remembering that light gives you far more bang-for-the-buck than does fast glass or the latest digital camera or 300/2.8) we'll move into basic technique. And after that, we'll keep it going with periodical essays and ideas on how to improve (or refresh) your lighting ability.
When you've worked your way through the basics of designing your light kit and learning how to use it, make a point to browse some of the examples in the "On Assignment" section. Those will be updated constantly, too. So keep checking back.
You will likely have some questions along the way. Sadly, it is not possible for me to take the time to personally answer all of the one-to-one lighting questions that pop up. So try to resist asking them in the comments section. The only people reading this behind you are the people who are, well, behind you.
You will find the one-to-one knowledge bank you seek in the Strobist Group on Flickr. There, you can ask away and get the diversity of response that you need. These are the lighting grad students, so to speak. They know this stuff, and are very enthusiastic about sharing their knowledge.
The Museum began acquiring photographs in
1852 and its collection is now is one of the
largest and most important in the world. It
holds over 500,000 images, by both classic
and contemporary photographers, and
illustrates a wide range of processes,
techniques and subject matter. The
Photography gallery focuses on the history of
photography, with an annual display of around
40 outstanding photographs from the V&A's
collection.

Click to view a slide show.With an impish smile, he glides behind our chairs, leaning over our shoulders to neatly frame pale yellow eggs, fat sausages, grilled tomatoes, and racks of thin, evenly toasted slices of bread. The 12 photographers gathered in the dining room of the Northbank Hotel-eight men, four women; some professionals, some enthusiasts-study him eagerly. We are on the Isle of Wight, a roughly diamond-shaped piece of land in the English Channel, for an educational weekend with Britain's pre-eminent documentary photographer. Occasionally Parr discusses technique and technology with individual members of the group, but mostly we learn by watching him. The lesson is simple: Photograph what you love.
Create your own photograph lighting with flashes and strobes. Learn about portable flash units for your camera in this free instructional video for beginning photographers.
Declaration of Principles
Kevin Sites in the Hot Zone is news reporting for the new millennium - a nexus of backpack journalism, narrative story-telling techniques, and the Internet, designed to reach a global audience hungry for information.
Our Mission and Goals
To cover every armed conflict* in the world within one year, and in doing so to provide a clear idea of the combatants, victims, causes, and costs of each of these struggles - and their global impact. With honest, thoughtful reporting we'll strive to establish Kevin Sites in the Hot Zone as a forum for information and involvement. Users will not only learn about the scope of world conflict, but will find ways to be part of the solutions- through dialogue, debate, and avenues for action.
How We'll Do It
We will be aggressive in pursuing the stories that are not getting mainstream coverage and we will put a human face on them. We will not chase headlines nor adhere to pack journalism but vigorously pursue the stories in front of and behind the conflict, the small stories that when strung together illustrate a more complete picture.
Veteran war correspondent Kevin Sites will travel solo to these conflict zones, aided by a U.S.-based "mission control" team: Producer Robert Padavick (NBC News, CNN) and Researcher Lisa Liu (Radio Free Asia, International Medical Corps).
Using the latest technology, including high-definition digital cameras and satellite modems, Kevin will deliver stories via a five-fingered multimedia platform of text, photography, video, audio, and interactive chat - all available on one website (http://hotzone.yahoo.com).

The Centre for Investigative Journalism (CIJ) advances education for, and public understanding of; investigative journalism, critical inquiry, and in-depth reporting and research.
CIJ is a registered charity offering high-level training, resources and research to the community, journalists, students, non-governmental organisations and others interested in public integrity and the defence of the public interest.
The Centre runs international summer schools, produces publications to help present landmark investigations, offers training in appropriate techniques, organises debates, speakers and screenings on critical issues - all designed to nourish the culture and professional standards of investigative journalism.
We are assembling a significant archive of investigative material. It can assist and defend investigations and provide research materials, advice and resources to NGOs, community activists, journalists and researchers. The CIJ offers particular assistance to those working in difficult environments where freedom of speech and of the press is under threat and where reporting can be a dangerous occupation.
