System information
Here is the same scene shot with the same PMW-F3 camera, but this time using the Sony S-Log1 (F35/F3)
color space (viewed here in 8-bit mode):
You can see that it doesn't have any clipping in the histogram (no telltale spike at the right):
However, the picture is very low contrast and is not ready for delivery. When you shoot with S-Log, you
aren't supposed to deliver that image as your final picture. You can view the image in Vegas Pro but you
must also do post-production work to create the final image for delivery.
When you unwrap the S-Log encoding into what's called a scene linear color space, you can't directly view it
on a standard display. You need to run it through a reference rendering transform (RRT) that compresses
the dynamic range and rolls off the highs and lows. The ACES RRT has been designed to be very film-like.
When we set this source media to the Sony S-Log1 (F35/F3) color space and view it using the ACES RRT, it
initially looks like this, which is quite a bit darker than the regular video:
