Grade School: Using HDR tools & film grain like a pro
Pro Colorist answers all of your questions about HDR tools, when to use them vs primaries, and how to best work with applying film grain.
0:06 Introduction
2:05 In which tone range is the film grain more visible?
6:40 What’s the difference between grain and noise?
10:58 Is film grain a viable option to mitigate color banding? Does noise help with
clipping?
15:21 We usually apply grain at the end of the node stack, right before the
LUTmaster look but photochemically grain is the last step when a positive print is
generated. Is there a difference if the grain node follows the look nodes?
20:24 My transformation to REC709 using automatic color management differs from
the one I get using color management in nodes. Why does that happen?
23:00 Is it better to use the HDR wheels on the clip level or at the timeline level? Do
you prefer turning the wheels freely or typing in exact numbers?
27:32 What are your thoughts on combining the highlights slider in the primaries and
the HDR highlight or ‘’light’’?
30:20 Can you explain what the ‘’Timeline working luminance’’ ‘’Limiting output
gamut’’ and ‘’Input/Output DRT’ settings are in DaVinci YRGB color management?
40:34 Choosing between DaVinci and Luminance Mapping usually creates a
difference in the red and yellow hues in the ODT. Why does that happen?
45:04 Can you demonstrate how to use the voyager LUT pack using ACES?
55:12 Does changing the pivot point in your contrast knob affect your mid grade
point set in your look?
58:59 What is the logic of applying gain to 0.5 in HSL and then 2.0 gain in HSV to
get subtractive color?
1:03:34 Final thoughts and conclusion
