I wrote the original version of this program more than 20 years ago to run on the Radio Shack PC-5. Some years later, after the PC-5 and its successors the PC-6 and Casio FX-795P had disappeared from the market, Ludo Hauduc, a professional programmer and amateur photographer, volunteered to port the program to the Palm Pilot. Although the Pilot interface was entirely new, the program functions remained essentially unchanged. Then David Rude, another professional programmer and enthusiastic large-format photographer, wrote an enhanced and expanded version to run on the Compaq iPaq, and similar PocketPC handheld devices. In addition he enlisted the aid of a friend and fellow programmer, Mike Morearty, to upgrade the Palm program to match the new capabilities of the PocketPC version.
Through all these revisions and improvements, the purpose of the program has remained unchanged; its aim is to provide serious photographers who work in large-format B&W with a device that can be trusted to provide reliable exposure and development information, so that they can concentrate on the art of photography without being distracted by technical concerns.
Of course this information can be no better than the data that the photographer provides, so this latest version has been integrated with the Plotter, an elegant program that analyzes the photographer’s own test data and calculates personalized working information for export to the Palm or PocketPC handheld device.
Although inexperienced amateurs can use the Expo/Dev program with generally good results, it has really been developed for photographers who are familiar with BTZS principles and methods and who understand what the device is actually doing for them. It is, after all, just a tool; but it’s a very sophisticated tool that will perform best in the hands of equally sophisticated users.
