Here is a brief overview of my image capture to print process.
For landscape photography, I use PhaseOne P45+ 39 MP Digital Back, Medium Format Mamiya 645AFD II camera body and Mamiya 645 AFD lenses. I capture both wide angel, as well as close up of nature.
For wildlife photography, I use 35mm Canon EOS 1Ds professional DSLR camera body (yes, I need to sell it) along with combination of Canon "L" zoom lenses.
All my images are being taken while camera mounted on a very sturdy tripod (except when I photograph from airplane and boat).
As I shoot digital, obviously I process my images in my own digital dark room. I use PhaseOne's CaptureOne 5.x to process RAW files and Adobe Ligtroom 2.x to organize my digital images. I use Adobe Photoshop CS4 to make local correction (color, contrast and saturation adjustments, dodge) and prepare images for print.
Once an image is optimized in digital darkroom, it is ready for printing as well as available for other output devices such as digital projection / web / DVD etc. For the time being, my color prints are made on Epson Premium Luster (250) paper from professional quality in-house EPSON Stylus Pro 4800 printer with Ultrachrome K3 ink set. B+W images are made on Hahnemuhle Fine Art Pearl paper. For image size more than 16" wider, I get those printed from a renowned professional lab, West Coast Imaging (See http://www.westcoastimaging.com).
According to Wilhelm Imaging Research (www.wilhelm-research.com), when displayed indoor, Premium Luster paper with Ultrachrome K3 ink set will have 165 year display permanence rating. This is entirely dependent on the display conditions, of course, and long life requires that these prints be framed for protection from air pollution, especially ozone. Full sunlight is roughly one hundred times brighter than daytime indoor display conditions. Indoor lighting levels vary dramatically, so it is possible a print near a bright window might begin to be noticeably off in color balance in as little as a few decades.
