What is D-Log Videography?
RAW capturing is a good choice for still photos, since it ensures all highlight and shadow details are recorded. However, for video, RAW is not supported in most consumer-grade cameras, and that is why we need D-Log, with which we can record sufficient dynamic range for effective grading in post production.
The LOG setting on high-end cameras maximises the dynamic range of video footage. For example, if you’re shooting in light levels with strong highlight and shadow components you are able to retain a lot more detail than shooting in the default settings.
Essentially, D-Log is used for the same reason still photographers shoot in DNG (RAW), which achieves a greater image depth. This permits greater flexibility in post processing.
Most recent DJI aircraft are equipped with D-Log capture capabilities. In D-Log mode, dynamic range and colour gamut recorded by the sensor is dramatically increased. Since a much larger dynamic range has been compressed down to 8 bit, the image shown on a common screen may seem to be quite flat, which is not suitable for direct viewing by the audience. As a result, post-processing is required to correct and grade the footage to generate a look pleasing to the viewer. During the grading process, you can selectively preserve or compress the tones that interest you most to preserve.
Terra Recon employs Apples' Final Cut Pro X with Cinema Grade FCPX, which is a modern colour grading software built from the ground up that runs as a plugin inside of our Final Cut Pro X on our iMac desktops. The plugin has over 90 built-in Hollywood style color looks with realtime preview of our favorite LUTs. The output is that dramatic cinema-look that our clients seem to love.
