IDEA 5 - exif data creates and image from an image

Everytime you press that shutter button on the digital camera, data is instanly stamped onto that image reminding the author of how that image was taken. Each detail is recorded the second that the light is read. The file is output as “Exchangeable image file format” or .exif for short.

Data is sorted as a table with the “tag” and then the “value”. Here are afew examples of the tags which store the data of the image.

Each of these will have differant data on each image. Some could be the same, such as FNumber but others such as focal length could have large veriances.

Using the data from exif files i would like to crate a generative visual piece of work. I would created the visualization in flash action scripted or more likely in processing (java environment).

Research is needed into how the exif data veries and how this might effect the outcome of a generated imaged in processing. I would also need to find a way of importing the data. Flickr.com manages to pull out exif data for display to i could use PHP inside processing to get this data, for another possabilty would be to use a processing libary which might have already been made, I know there has already been an MP3 ID Tag created.
