A tool that combines two idiosyncratic tools that I personally use for cinematographic purposes. The first tool is used to measure the distances required to place a convex mirror, the corresponding light source and its target subject, to emulate the size of the Sun. The idea comes from Jarin Blaschke's (cinematographer) film Nosferatu, where, together with Gordon Arkenberg, they calculated this distance. The second tool is inspired by the paintings of the Renaissance and by Salvador Dalí. It allows the user to generate Fibonacci spiral frame lines to overlay on an external monitor, to help achieve golden compositions.
