Timeslice (Derwent River and Dark MoFo looking north from Evans Street, Hobart, Tasmania, June 2016)2016
Artist statement: The Derwent Project is a collaboration between David Stephenson and Martin Walch that visualises the environmental dynamics and passage of time in Tasmania's Derwent River watershed. The Derwent time-lapse array is one method explored; twelve camera stations, each recording still photographs every five minutes, are dispersed throughout the watershed in key representative environments ranging from wilderness headwaters to urban estuary. These photographs allow environmental dynamics such as weather, water levels, tides, and urban development to be traced. Multiple outcomes for the photographic data include the recombination of selected individual files into a composite matrix, and the slicing and recombination of sequential frames into ‘timeslice’ images. Both methods allow the passage of time to be represented spatially across the image.
Also known as Giclee prints or bubble-jet prints, pigment ink-jet prints are generated by computer printers from digital or scanned files using dye-based or pigment-based inks. A series of nozzles spray tiny droplets of ink onto the paper surface in a precise pattern that corresponds to the digital image file. In dye-based prints the ink soaks into the paper, whereas in pigment-based prints the ink rests and dries on top of the paper surface.
Whilst the term is broad, pigment ink-jet prints have come to be associated with prints produced on fine art papers. They are the most versatile and archival method of printing available to photographers today. A wide variety of material on which an image can be printed with such inks are available, including various textures and finishes such as matte photo paper, watercolour paper, cotton canvas or pre-coated canvas.
