Much More Than A Curve Generator! Check it Out!
Precision Digital Negatives for Silver & Other Alternative Photographic Processes, an eBook on crafting the best digital negatives possible!
The Precision Digital Negatives System is the finest SYSTEM available for crafting a digital negative. Using Photoshop and a good quality printer, the eBook gives instructions on file acquisition, working image files, making digital negatives & the calibration process that produces negatives custom tailored to your equipment, workflow and alternative process. The unique, patented, Color Density Range Control is a LOSSLESS method of tuning the negative to the requirements of your alternative process—resulting in far less drastic and less destructive adjustment curves. This system can do things that are impossible with any other system.
Users are also getting fantastic results with Photopolymer Gravure (or Solar Plates) using Precision Digital Positives.
NOW AVAILABLE! Curve Calculator II For Windows - Much faster & easier! Not just an upgrade to the old Curve Calculator, CCII is a stand alone database with versions that work on either Windows or Mac (Leopard compatible) platforms. All of your calibration information can be kept in one place! CCII generates a family of hybrid curves for each of your alt process calibrations—choose the hybrid curve that is the most pleasing to your photographic vision and export it automatically in Photoshop curves file format. See my article on PDN, Curves, and Curve Calculator II in the November/December issue of View Camera Magazine. Curve Calculator II requires a standardized 31 step tablet.
Standard Film 31 Step Tablet If you do not have a standard 31-step tablet (a film sensitivity guide) for calibration, you will need one. A 31-step provides increased accuracy in calibration over the 21-step tablet. You can purchase one here that I have designed and is produced for PDN by Stouffers Industries—the price is very competitive and it has improved features that make it much easier to read the results. Note that the 31-step tablet will be required for Curve Calculator II.
