  1. I haven't been able to find an answer for the discrepancy between the Scopes Histogram and the HDR Zones Histogram. I've attached 2 pictures below showing the Histogram for a Gray Scale ramp and the settings I'm using(I know they're not HDR. I was just trying to understand what the HDR Histogram is actually showing). I understand the x-axis represents the tonal range(in stops rather than the typical tones in the primaries curve) and I understand why it ends at a 100 nits (The limitation of SDR being a 100 nits) but why is the histogram an exponential curve on the HDR Zones whereas it's a straight bar in scopes as it's supposed to be (all of this is at default settings). On top when I change the Output Color Space to Rec709 2.4 it's still an exponential curve and ends at a 100nits but the Y-axis is only like 1/4th way up. Basically, what does Y-axis actually represent both for the Histogram and Blue Curve/Line in HDR Zones? Thanks P.S: I'm not a pro colorist or anything. Just someone who is genuinely interested Output Space sRGB, Timeline Working Luminance: SDR 100 Output Space Rec709 2.4, Timeline Working Luminance: SDR 100 Output Space sRGB/Timeline Working Luminance 4000 HDR(Just another example) Scopes Histogram(Always stays the same)
  2. Can I use colorspace transform instead of a conversation lut ? What are the differences here? I am hoping someone will shed some light on this for me. Thanks
  3. Hey everyone, I need a little help here. I have a Project shot on Red Epic (Prores 444, 2k), I'll be color grading on davinci resolve 15 studio. This Project will be Projected in Cinemas (DCP, and Private watching on Tv) So my question is should I Work on Rec 709 output and than convert it to DPC using DCP O-matic ? Or should I Work on P3 Color Space output ? (I will be using Ipp2) Thanks for the help !!
  4. I often hear and read here that nobody transforms LogC (or Red, or whatever) colorspace gamut to destination gamut. For example from AlexaWideGamut to Rec709 gamut. Everybody just makes a contrast curve, then some LGG, and that's all. Even If I go this way, I still use a gamut conversion LUT after normalization curves. Or I use gamut (colorspace) conversion plugin after the curves if I'm on Resolve. Why do many colorists skip this step?
