Toland (named after Gregg Toland, ASC, cinematographer of Citizen Kane, The Best Years of Our Life, Grapes of Wrath among other films, as well as being an innovator in the use of light) combines a calculator and logging interface that tracks photographic choices as they are made. Changing the camera speed will bring up feedback on how this affects running time and exposure; changing a lenses, will derive Depth of Field and Field of View updates in real time. If desired, Toland then allows a log to be created with all this information, building comprehensive camera reports throughout the process.
