The RED DSMC Field Ops Guide is a 54 page PDF that covers the fundamentals of working RED Epic and Scarlet camera bodies. Much of this information applies to RED Weapon and Raven cameras as well. In the guide you'll find information on how to use the In Camera Tools, a concise overview of how ISO/FLUT works on RED Cameras, quick reference for common things like Resolutions and Formats, as well as some of my personal notes on operating RED cameras.
Included with this purchase are both High Resolution and Mobile Optimized copies of the RED DSMC FOG. The PDF is optimized for on set reference and features links to and from the Table of Contents in order to quickly navigate to the information you're after.
