saturation like Mitch BOGDANOWICZ method ??

Recommended Posts

What are you specifically trying to achieve? I think you can already get some interesting kinds of saturation by using the tools within Resolve: Cullen Kelly has demonstrated placing one node into HSV space, turning off H (Hue) and V (Value) and then using gain to bring up Saturation. It's a different look than the normal Primaries Sat knob, which is based in RGB.

Cullen's video is fairly informative:

I'm not sure I'd call it "cinematic" per se, since that's kind of a word that gets thrown around an awful lot. But it's an interesting alternative to trying to turn color level up with the Sat knob, or with the Color Warper -- which can be put in different modes as well (HSP, HSY, HSL, and HSV). A lot depends on your expectations and the time available.

I also wouldn't underestimate the Color Boost mode, which can do some interesting things under the right conditions.

Graded with the help of Niran film print developed by Mitch for Ravengrade 


Mitch’s 2383 is Onyx. 

(lovely work in that grade btw).

I do find that the implementation of Onyx in Ravengrade clamps max saturation quite a bit earlier than Mitch’s original 2383 xyz model that I assume the Ravengrade version used as a source, however that is just my own speculation since both the original LUT and Ravengrade version are almost identical apart from the saturation clamp.

Is there anybod out there to explain ?? it would be great help . Thank you 

Mitch’s 2383 is based on a large data set. However I assume the overall ‘look’ you are referring to re saturation is the subtractive nature of a film print’s saturation, which his 2383 models.

There are many ways you can achieve this type of subtractive saturation, but essentially you would need tools that can lower the density of a hue and also saturate/expand it. Typically with subtractive saturation as a hue becomes more saturated it also becomes darker. The saturation knob In resolve will have the opposite effect because it is additive, it linearly expands out all colours and perceptually increases their luminance as it does so. So as you apply saturation colours will become bright and garish, especially those that are already near the gamut/cube edge.

When you apply a more ‘film like’ saturation lower saturated areas will become more saturated quicker than higher saturated areas, so for example skin will become saturated but car tail lights will hold where they are. This is a non linear type of saturation and can have very beautiful results.

Nobe color remap / color warper can be effective tools for experimenting with density and saturation of a hue across a hue’s luminance and saturation. And as already pointed out, playing with S in HSV can also give a subtractive style of behaviour. Paul Dore put out a free dctl I believe called film density which applies hsv saturation. Different colour models behave differently, it can be fun to experiment!
