If you thought you could calculate accurately the depth of field of your photographs just by using your pocket calculator and the hyperfocal distance, think twice. If you require working with precise values based on the aperture of the lens you’re using, its focal length, the distance from the lens to the subject, and the circle of confusion, you need Photo Calculator, a tool designed to provide professional photographers with accurate depth of field and hyperfocal distance values.
The entire program’s functionality fits in the program’s compact main interface. Here you will find both the parameters you need to define to perform the calculations and the resulting values. Photo Calculator supports a wide range of film formats from well-known professional camera makes and models, such as Canon, Nikon, Olympus’ four thirds lenses, Leica, Casio, and even Hasselblad’s 44x33 mm film format. Once you’ve selected the one you’ll be using, you’ll be asked for the resolution, which ranges from 3 to 6 line pairs per millimeter. You can then calculate the circle of confusion manually or let Douglas Photo Calculator to do the math for you (recommended) based on the previous resolution and the film format values you entered. Next are the aperture and distance values – the former can only be selected once you’re registered your copy of the program for a ridiculously low amount of money, while the latter can either be entered manually or calculated using the hyperfocal distance. more
