RED Tools is a convenient reference tool designed for use by filmmakers and camera operators to outline best practices in camera set-up for a variety of shooting situations. Each tool is customizable based on a selected RED camera and sensor type. Standard film formats are also included for comparison. RED Tools is also included in the RED Control app, which also provides free, full-featured camera control and video streaming for RED’s latest DSMC3 products. TOOLS INCLUDED: CROP FACTOR Preview how a given focal length will appear depending on resolution setting and sensor type. Illustration depicts viewable area relative to a traditional 35 mm stills photography sensor by default, but other reference sensors are selectable within the drop-down menu. R3D RECORDING TIME Evaluate the video data rate and available recording time based on your RED camera settings. This can help you understand media requirements and production costs in advance of a shoot. FLICKER FREE VIDEO Find a flicker-free shutter speed and frame rate combination when shooting under artificial lighting. DEPTH OF FIELD Understand how various camera settings influence depth of field. PANNING SPEED Estimate the panning speed where judder will likely become too pronounced. The goal is to provide a more accessible tool than the charts and tables commonly referenced in cinematography manuals. It uses the standard rule of thumb that camera panning should not cause objects to transit the entire horizontal extent of an image in any less than seven seconds. EXPOSURE Assist with exposure when one camera setting has to change. Example usage scenarios include when a higher frame rate needs to be used for slow motion, when the T-stop has to change for depth of field, or when the shutter angle has to change to minimize flickering in artificial light. NIKKOR Z Lens Coverage Use this tool to understand how NIKKOR Z lenses will look on your RED Z Mount camera bodies. The tool shows the extent the light will fall off at different sensor formats, and if any hard vignetting occurs.
