I also provide services to print digital negatives from digital files for both platinum-pallidium and silver gelatin contact printing. I have a professional printing lab and provide services for Platinum-Palladium Printing, Silver Gelatin, and Piezography Carbon Printing. I also conduct photography tours around the world. I offer workshops for small groups and individuals for platinum printing and silver gelatin darkroom process. I have been teaching photography and print making to both amateurs and professional photographers. I am a print maker and a professional photographer. I also found the monochrome files were very flexible and cooperative in the postproduction process. With monochrome, I have a full control of my exposure in the field as opposed to the film. However, in my opinion, the tonal range and the smooth transitions of the tones are superior in the monochrome files. I selected these countries because of the interesting cultures and open landscapes that yielded well to B & W photography.Ī black and white image converted from an RGB file shot with a digital camera works very well for platinum printing and can be used to make a digital negative. My collection of images in my blog from Iceland, Romania, Morocco and Kenya were shot with Leica Monochrom. Leica Monochrom provides high quality files with rich tonal range, which adapts very well to platinum printing. I have always used analog black and white film for my platinum printing. To exploit the full potential of platinum process, an image with a wide tonal range is very important and essential. In these all-digital times, this classic technology wins the hearts of photographers, collectors, galleries and museums. It is the other end of the spectrum of commercialized ink jet printing. Platinum printing is for individuals that enjoy the value, effort and satisfaction of handcrafting. A personal touch plays a big role in the platinum print making process. The work is labor intensive, but the finished results have the signature and soul of the artist. Each print is completely unique and one of a kind, making the process extremely special. It is then air-dried.īecause of multiple factors affecting the print process no two prints appear the same. Finally, the print is washed extensively with water to leave behind only the pure metals platinum and palladium. The print then goes through 2 successive clearing baths, each lasting 5 minutes to remove any remaining photosensitive compounds. After the exposure, a “developer” is then poured on the paper to complete the reduction of metal salts to pure metals as the image appears. Once the paper is dried and humidified, the negative and the paper are placed in a contact printing frame and exposed in intense ultra violet light. The solution is then coated carefully into the paper. It begins with the preparation of a photosensitive solution containing platinum and palladium salts in different ratios are mixed with ferric oxalate. Platinum printing process is entirely made by hand. A number of factors such as the ratio of platinum and palladium, the kind of developer, the relative humidity and restraints that are used, can vary the appearance of your print. This process gives tones that range from cool/warm blacks, neutral grays, to rich sepia browns that are unobtainable in silver gelatin prints. I use Hahnemuhle Platinum Rag and Arches Platine, a 100% cotton water paper. If properly processed, the print can last over a thousand years. Because platinum and palladium are noble metals, when they are embedded in the fibers of the paper, it makes the print unalterable and indestructible.
