Mac users can put their calculators away - Douglas Software has announced the release of version 1.0.0 of Camera Module for Macs.

The software, previously only available to PC users, provides a photographer with instant assistance in solving many day-to-day optical equations such as angle of view for selected lens and film format combination, depth of field, including near focus, far focus, total depth of field and hyperfocal distance, as well as image width and height.

The Camera Module covers 37 digital formats including 9 digital backs and 12 conventional film formats, and can calculate optical equations in just a few clicks. Simply enter the specifics into the software, such as camera type, lens and aperture, and the programme will immediately respond with a figure for the equation you need.

Camera Module for the Mac 1.0.0 runs under Mac OS X 10.2 or later and costs $75 (about £38). Registered customers are entitled to unlimited functionality and free technical support. However, you can grab a no-cost demo version, where the aperture is fixed at f8, from their website.
