contextual pictures taken with mobile phone cameras, which include the alternative, otherwise 'hidden' environmental data dimensions (e.g. sound, temperature & pollution) as aesthetic visual parameters onto the images themselves.
in practice, a digital camera senses these parameters, & affects the image accordingly with artistic (~Photoshop-like) filter effects in real-time. the photographers are "not interested in having the contextual information available in raw data as a supplement to the image file, but preferred to explore the visual effects."
