Lighting for video is part art and part science. In order to master the art one has to have a firm grasp on the science. There is a wide array of professional lighting options and fixtures for anyone making video.
A characteristic of true professional video lights is the ability of a particular fixture to produce consistent photometric characteristics, the same light over and over again without variance. Anyone familiar with professional video lights is familiar with the Arri brand of lighting. Arri provides a wide range of precision lighting instruments for a diverse number of uses. There's a great benefit in having many video lights made for specific uses. The only downside is the amount of knowledge it takes to fully understand what each light does. For someone who is new to lighting for video, and even for seasoned professional, lighting can be tricky if they don't know what their video lights are capable of. This past month the Arri Group released its Photometrics iOS app.
Photometrics iOS App
The Photometrics iOS app lets the user reference the photometric characteristics of different Arri light fixtures. The app only references Arri Lighting but considering the popularity and availability of Arri lights, it's a useful tool to have. The Photometrics app will give the user information on a lamp's luminous output, beam diameter, beam angle, luminous distribution graph, light properties, physical properties, and just about any other detail that is of importance to a lighting director. For anyone interested in lighting for video, even if they don't have any Arri fixtures, it's an informative tool and will help them pick up the lighting vocabulary that sometimes seems foreign on set. The Photometrics app is free in the iTunes App Store.
