LFTools is an app for Large Format and Film Photographers. In version 1.5.0 LFTools contains 2 Tabs. The first one is the 'LF Tools' tab, with several sub sections. Each section has a tool to calculate certain properties which are used in large format photography. Like extended exposure times with regard to bellows extension or the magnification from a bellows draw for a given focal length. The second tab, 'Film Reciprocity', contains the Film Reciprocity Calculator. This calculator is of interest for all film photographers who are interested in long time exposure. With the Film Reciprocity Calculator one can overcome the so called reciprocity failure, which is inherent to almost all films. It is quite simple to use, one just has to select a film, shutter speed and aperture an the tool automatically creates a table with extended exposure times. The app comes with a pre-populated list of films from Ilford. Ilford was the only manufacture who publishes the p factor for their films. Al be it, the user can add its own films for calculation.
