EXIF Meta Data
Since the dawn of the digital age, photographers and others who handle digital images on a regular basis have struggled with keeping track of the spread of their images. Because digital images are easily copied, a photograph published online could end up easily on a thousand websites. Just as the music and film industries have been forever changed by illegal downloading, the imaging industry faces similar challenges when it comes to tracking, copyrighting, and protecting their digital media. In the age of Google and Yahoo Images, many people feel that they have a right to download, copy, and distribute any of the images that they find. It seems that the world will never grasp the concept that the internet is still bound by the same laws that outlaw copyright infringement and theft. Most people accept that they cannot walk out of a store without paying for their groceries, yet willingly copy and paste images off websites or online photo galleries. Google Images easily becomes the Napster of digital images.
So how do we combat this as people who work with and publish digital images? Well, for starters, EXIF meta data is now embedded into almost every file created from a digital camera. This data tells us when the photo was taken, by what camera, and all of the information about how the photo was captured. We can tell what film speed, aperture settings, and shutter speed the camera was set for when the image was taken. Many photo editing softwares now allow us to embed additional copyright information into the meta data. Now, these photos are easily tagged with a digital fingerprint that can reveal the ownership of any published image.
Jeffrey Friedl has created a great online tool for checking the EXIF information of any image, even if the image is on your computer and not published on the web. I have posted the link under photography links at the bottom left of this page. There are also links to great resources for more information on EXIF meta data and copyright laws for digital imaging. As an advertising and web design company, we have a great responsibility in how we license and manipulate images. Stock Imaging companies require strict licensing procedures and hired photographers usually do as well. Since I consider myself a semi-professional photographer, this subject is very important to me. As with any art, a photograph is the intellectual property of the one who takes the picture and their wishes as to it’s use should be strictly followed.
