Color Crosstalk - DaVinci Resolve DCTL

hey I'm God I'm a freelance colorist and DC cell developer and in this video I'm going to Showcase my color crosstalk DC till this is a tool that takes multiple steps that all can all be done in DaVinci Resolve and automates most of them so you can focus on the creative side of loot creation and this tool allows you to turn an image like this into this well let's see how to use it so I have set up a node-based color managed project with this lovely image from Ari going from Ari white gamut log C3 to DaVinci white gamut intermediate and to rec 709 gamma 2.4 that being my monitoring displays color space and let's write two serial nodes so we can compare the built-in RGB mixer found here and my DC tell let's have this be it a RGB mixer and this beady dctl to access the dctil go up to effects search dctil and drag it on and here you have a list of all your digitals which can be put in your Lots folder and we're going to find the color crosstalk in this case version 1.2 DC tell out of the box you can see that the DC tool does nothing to the image we can confirm this by turning the node on and off and looking at the Scopes and to make the DC till work as similar to the built-in RGB mixer as possible only doing one automation I will disable Ankara skin tones and work in linear now let's do the first test in the RGB mixer let's add some blue to the green Channel and what we can see is that the whole image becomes a huge green mess this is because we have shifted the overall balance of the image and to restore these patterns we will have to take these values and divide them by a number so that the total becomes one once again in this case we have to divide both of these numbers by two and we can see we have achieved our result and to make it as simple as possible we'll also disable preserve luminance now having done this let's grab a still to compare later and let's do the same thing with my DC tell let's take blue and green slide it to one and we're done now if we compare you can see a tiny bit of a difference on the Scopes but the color channels themselves aren't really moving it just seems to be some kind of noise now the next thing you will probably like to do is to move the skin tones back to where they were and the simplest and most non-destructive way to do this is to actually shift or rotate to Hue off the whole image and we can try to do this visually by using the Hue rotation control on the primary color wheels panel and let's just disable the node okay we can try to do it visually but well we can never be completely sure that it's precisely what we started out with in terms of hue so in my digital you can check the anchor skin tones checkbox and it performs the Hue rotation for you automatically returning the skin tones Hue to what they were at the beginning if you have skin tones with a different base Hue then you can use the skin tone offset slider to Target those you don't have to know the precise value you can just play around with the slider until the skin tones look correct once again and finally there's the work in linear option to use this you will also have to select the correct gamma you're working with in the gamma drop down in this case we have DaVinci intermediate and when I check linear you can see that the changes become more soft which is something I personally like and thus is the default setting for this dctil well there you go if you like what you saw you're going to find a link to the tool down in the doobly-doo and till next time bye
