LuxOratio works simultaneously as a Ratio calculator for anyone working with more than one light source (photographers, lighting engineers, photo directors, decorators, scientists) and a notebook.
The Ratio calculator at the core of the application determines up to 280 different combinations of light intensity and can save and store the results. The notebook function lets you add various information such as equipment used, distances and other relevant information. The notebook therefore provides a memory aid while using the iPhone camera to add visual references.
