We've been hearing rumors that Canon will be releasing a firmware update for the Canon 5D Mark IV that will make it possible to capture in C-Log, Canon's own log file format, and that they will be making it available during NAB in Las Vegas next month. Whether the Canon EOS-1D X Mark II will get the same update is still unclear, but reliable sources have made it known that the 5D Mark IV is definitely getting updated.
What is Log?
Capturing in Log isn’t the same as capturing in raw. It’s a special way of capturing that maximizes the tonal range of a sensor by spreading the corresponding input/output luminosity function across a greater range, resulting in a low-contrast initial image, but allowing for more tonal range to be captured. Therefore, it might look flat and desaturated during capture, but it gives much more dynamic range and room for post-production and the use of LUTs (Look Up Tables) than a regular compressed video file would offer.
This will be a great added feature for the photographers who already updated to the Canon's latest full-frame camera and will most certainly convert the photographers who were looking around for extra video capability. Canon Rumors is reporting that the upgrade may require sending your camera back to Canon, however. We'll know more soon.
