maxotics Posted July 7, 2017 Share Posted July 7, 2017 I did a video on this (2nd try) but it's very dull (link below). My question to the forum is this, what am I missing in this logic? 8-bit video captures roughly 16 million color values Human vision is around 12 million (but let's call it 16 million) Human vision, is around 5-7 stops of dynamic range (without pupil change) CONCLUSION ONE: 8-bit color can deliver a complete color representation to a human; that is 16 million colors over a 6-stop gamut, let's say. In S-LOG, one is widening the dynamic range to 10 stops, let's say, and spreading color information across the fixed 8-bit data space, which means we're losing saturation compared to the 16 million colors over 6 stops? Compounding the above's theoretical question, a sensor becomes noisy or erratic a few stops above and below a range where is can accurately do #4; Therefore, doesn't one trade 16 million colors of better saturation for few colors and noise? (that's my finding after doing some experiments). My current conclusion is S-LOG is not really about dynamic range, unless you interpret that as capturing only brightness values in the wild. S-LOG is a "look". I'm personally tired of it, but that has no bearing here. The question is, isn't it a misnomer to say LUTs put the color back in? When one shoots S-LOG, aren't they walking away with more noise than accurate color values in which to apply the LUT? Will S-LOG look very dated and washed out in the future? Why isn't there more discussion of the destructiveness of S-LOGs on color data? Thoughts? PannySVHS 1 Quote Link to comment Share on other sites More sharing options...
