James Ward - FoCal Previs Assist

TO LAUNCH, CLICK ON THE NAV-BAR BUTTON AT THE TOP OF THE EDITOR OR RUN THE EDITOR UTILITY WIDGET CONTAINED WITHIN BLUEPRINTS.


The FocusCalculation Previsualisation Assist tool aids in the previs stage of production. It provides Field of View (FoV) and Depth of Field (DoF) information that is calculated from sensor sizes, the relevant CoC (Circle of Confusion), and lens data (either from live camera data or manual input).

It will calculate and display in real time both the DoF (Including Hyperfocal Distance) and FoV with both viewport guides and editor widget guides.

The tool is aimed at helping productions by allowing the testing of shots with different camera settings so that decisions about Volume & LED-based walls can be made before production begins. Allowing for the process to be more efficient and for DP's, Directors and Camera Operators to make better informed decisions about the shots that they want to include in their productions.
