Pip uses archival materials to assure utmost permanence of his images. Combinations of ink and papers are evaluted for best reproduction and permanence. While digital imaging has not been around for long, accelerated testing indicates that all his finshed products should have a lifetime of at least 100 years. All matting and framing materials are similarly selected for archival life.
Pip uses a Nikon D7000 camera with 18-200 mm zoom lens for visible light and a Nikon D5100 with 18-55 mm zoom lens for infrared. The "standard" (715 nm) infrared camera conversion was done by Digital Silver Imaging in Belmont, MA.
Printing is done by Pip on two Epson R1800 printers. Color is printed on a stock Eposn R1800. For black & white a second Epson R1800 was magnanimously provided by Woody Stack, fully converted to a Continuous Ink System (CIS) using Jon Cone's Piezography K7 Neutral system of inks. Piezography uses black ink plus 6 additional shades of gray (very dark to very light) to fully capture the continuous gradations and range of tones. Imagine printing a very light gray with only black ink: you would get one dark spot in a filed of white. Splat. Piezograhphy intead fills the area with the appropriate tone. A vast amount of information on Piezography is available at http://www.piezography.com/PiezoPress/ for those up for a good science project. The results are extraordinary.
