alt Hacker NewsFor those who are curious, this is basically what we do when we color grade in video production but taken to its most extreme. Or rather, stripped down to the most fundamental level. Lots of ways to describe it.
Generally we shoot “flat” (there are so many caveats to this but I don’t feel like getting bogged down in all of it. If you plan on getting down and dirty with colors and really grading, you generally shoot flat). The image that we handover to DIT/editing can be borderline grayscale in its appearance. The colors are so muted, the dynamic range is so wide, that you basically have a highly muted image. The reason for this is you then have the freedom to “push” the color and look and almost any direction, versus if you have a very saturated, high contrast image, you are more “locked” into that look. This matters more and more when you are using a compressed codec and not something with an incredibly high bitrate or raw codecs, which is a whole other world and I am also doing a bit of a disservice to by oversimplifying.
Though this being HN it is incredibly likely I am telling few to no people anything new here lol
"Flat" is a bit of a misnomer in this context. It's not flat, it's actually a logarithmic ("log profile") representation of data computed by the camera to allow a wider dynamic range to be squeezed into traditional video formats.
It's sort of the opposite of what's going on with photography, where you have a dedicated "raw" format with linear readings from the sensor. Without these formats, someone would probably have invented "log JPEG" or something like that to preserve more data in highlights and in the shadows.
