Never seen this before and I seriously appreciate your willingness to share this golden nugget. I prefer the subtractive color look WAY more than the standard look so this is incredible.
I've used DCTLs to do subtractive saturation in the past , but the beautiful thing about this approach is being able to use Gamma and Gain to adjust the saturation curve. For example, pulling Gamma and Pushing gain to get a relative normal saturation approach throughout most of the tonal range, but then quickly ramp up to a punchy saturation at the upper sat range. It feels like magic. Conversely, pushing Gamma and pulling Gain to get a really even and holistic saturation response throughout the whole tonal range before dipping to 0 for neutrals. This is brilliant. Thank you for this!
My man you are SURGICAL in your methodology with color grading, more than anyone else i've seen online. I just up davinci and have been binging all of your tutorials, glad I found your channel on the path to greatness!
Looking forward to this discussion. Thanks Cullen. this method triggered my memory of learning something similar where you have a node set to HSL, turn off the channels - and set the luma mix to 0 - and decrease gain, Then add a following node and set it to HSV( remove the channels ) - luma mix to 0 and then bring the gain up. This makes deep saturation that changes and leaves blacks and whites clean.
@@m1nt9reen Disagree - to have the colors look denser the Y channel shouldn't change with the adjustments. If you try it with and without changing the luma mix to 0, they are slightly different results. So then it becomes a subjective move.
@@JimRobinson-colors they are not slightly different, they are 100% identical. The luminance mixer control does nothing when in HSV, even if you keep all channels enabled.
@@m1nt9reen Actually you have a point and I surrender to your argument. Just note that I made that assumption from seeing it done in the past. But I believe you are right now that I think about it. When doing this process - I am not sure how it is being compressed where if you push the HSV that it still seems to remain in the safe region on the vectorscope. Thanks for pointing out that.
I love your videos and thank you so much for sharing! On the next one, could you possibly move your camera window to the lower right side instead? We can't see anything you're doing on the primaries or curves. Thanks and keep it up! It means the world to us trying to improve our color correction and subsequent grading in Resolve!
This is the only brilliant, simple explanation I ever found on youtube. I appreciate your willingness to go this much deep into this subject I struggled to find the right amount of saturation. Looking forward to your next video. Thank you!!
Best tip of the year for me. I try to never use the SAT knob, as I never liked what it did, and if I did use it, then I always ended up trying to counter the overall SAT increase with a Sat vs Lum curve to get deeper colors, but this is exactly the technique I've been looking for. Thanks so much for sharing this Cullen.
This is amazing. Using your lift gamma gain method on a saturation channel gives a much better result than the saturation knob alone. I was wondering why my saturation adjustments looked so 'cheap'. Now I know!
So this is how it's correctly done. I've been trying to achieve this by increasing the saturation knob and decreasing the overall luminance. This really helps. Thank you!
Hi Cullen - awesome tutorial for quick saturation boost. I am using this a step further for getting the filmic "Subtractive Color Look", that is about making more saturated colors a bit darker, but w/o changing overall saturation at all: 1) just put 2 nodes in a row - first node is HSL, 2nd node is HSV 2) adjust Gain of the 1st node (HSL) back to 0.5 3) adjust Gain of the 2nd node (HSV) up to 1.99 (ideal Would be 2.0, but DR allows only cranking up to 1.99) The overall saturation remains the same after the 2 multiplied S-channels of the 2 nodes, but by applying first HSL and next HSV you get the darkening effect on higher saturated parts And, now your trick comes into play: If you want to get the overall image more saturated, plus the cinematic effect enhanced, just add your explained HSV node before both (as node 0 of now 3 nodes) and manipulate only the saturation with all the tricks you explained in your video - awesome results that come very close to saturation behavior of true film material because node 2 and 3 will have more saturation to take effect on. Thanks so much for sharing your trick because I was always using the Sat attenuator for node 0 - now I get the saturation I always wanted.
@@joyoffilming9500 I try your node construction. 1st node HSL with channel 1,2 and 3. 2nd node HSV with channel 1,2 and 3. I adjust the gain to 0.5 for HSL. on the second you say you can only go up to 1.99. but the gain can go much higher... Something I don't understand. /// 3) adjust Gain of the 2nd node (HSV) up to 1.99 (ideal Would be 2.0, but DR allows only cranking up to 1.99)///
@@fartsmr5100 Sorry for ma late response. Here some things to consider with the 2-node HSL sequence for getting that deep dark saturation: 1) set the color space of both nodes to HSL (HSV would also work here) 2) uncheck both channels 1 and 2 - this leaves only the channel 2 which is the S-channel (= saturation channel) 3) Go to the primary wheels and adjust with the Gain-wheel the saturation values (node 1 = 0,5 and node 2 = 1,99) In the meanwhile, I use DCTLs for such as gentle color weighting and film density - but, you can achieve much of it with the 3-node combination (Cullen + my 2 nodes) Hope this helps a bit.
Awesome video! This process gets me closer to what I do on the photo side, where I create a saturation mask before manipulating saturation to affect the lower saturation parts of my image more. Thanks for sharing your knowledge, Cullen.
I mean bro, your Pro for a reason, cuz the first image looks doper than a lot of stuff I've tried to do. But second image using HSV for saturation was even more awesome. Dope tutorial bro!!
Amazing lesson as usual. Only thing that would help us viewers would be if we could see your primary wheels when you’re adjusting them. Even if it was something as simple as cutting your ARoll for those moments, I think that would help a lot. Another step further would be to also scale up the primary window as it’s being adjusted to help with its readability.
Thanks for the easy but pro way of doing it. I just watched a 20min add that made this with a much more complex set of nodes separatin the values and then subtracting form the origianl image and then adding it again, also using the qualifier to chose wich color to saturate more o or less, to achive more or less the same results, and ending the video with "this looks great but its REALLY complicated, thats why we recomend this U$D100 plugin to make it all inside one node" ...
Thank you for sharing this technique. Exactly the result I knew that I could get from my 10 bit footage but was having trouble getting it there. Huge improvement!
THANK YOU FOR THIS VIDEO! genuinely game changing for me. I hate what the saturation knob does, especially on 8bit & 10bit footage... and you've just set me free. I am forever grateful
@@cicolas_nage nah homie, i dont think you understand my comment or the video. No one said anything about footage breaking and also the way saturation methods react mathematically and visually with different bit depths is very much a thing.

This is my first time coming across Cullen. I got his name from another colorist on UA-cam. Cullen is phenomenal. He seems to understand how the basic colorist thinks and is able to translate how you should think before approaching a project rather than what to do. Does he have a masterclass?
Very useful information! However, the adjustments that you were doing were overlapped by your video. For a relatively new user like me, it helps to watch the adjustments being made. Thank you!
Every time I pull up a Video of yours & learn something new out of it. Realizing I'm learning from the God of Page 6 on Resolve. Can't Thank You enough Man. Also you told me to check the Wide Gamut Workflow series which I did & now I operate the same way like you taught. It really makes the workflow easier.
Hey Cullen Can you please make a video about how do you use your own 2382 LUT, using the layer mixer technique “combination between color\contrast” in such a template Node Graph, where you exactly put the LUT with the layer mixer in front or after the parallel !! How and Why !! Thanks in advance
Based on your definition/explanation, I would say this is a good approach to implementing vibrance control, as opposed to saturation (using the gamma wheel)
holy crap, I just tried this, its so much better this way, I have been trying to bring out the blue sky in my off road videos and the normal situation makes everything else way to vivid, like tree and clay etc so I just kind of gave up with it except for a very mild boost, this is exactly what I was looking for
This is one to rewatch for sure. Working as a photographer I tend to avoid saturation controls like the plague (though Capture One Pro is bearable for a quick fix). When I started out with Resolve I notice that more often or not if I was experimenting colour boost was was often preferable. Due to bugger all work lately, or real projects, I have not used DR much so can't remember why!!
This is a phenomenal approach -- working with log profiles I often feel like I have to push the image too hard to get proper sat. Just making sure I understand: on this model, gain adjustments will target the more saturated areas of the image, gamma the middle of the image, and lift the lowest sat parts of the image?
That's a really brilliant idea - something that, once it's been explained clearly, seems really obvious but which most of us simply hadn't thought of at all. Nice one! I must also compliment you on your presentation style, which seems to me to strike the perfect balance between putting the information across and not patronising the target audience. Making videos is a sideline for me but I like to do things properly and I'll be making a point of watching more of your material in the very near future.
This is huge for me. I used to love sat vs sat and sat vs lum / hume vs lum , it served quite well in different situations , but curves tend to break the image easly , Gotta try HSV out 🔥🔥
Great video as always Cullen! Saturation is one area which I really want to explore more deeply, so hopefully you'll get into more detail on the subject of subtractive saturation and other stuff I probably have never heard of yet. I do have one question regarding the different colorspaces and contrast: how do different color spaces affect contrast? Or does the contrast operation yield the same results across all color spaces? Since it affects the saturation as well, it would only make sense to have different results in different color spaces. Looking forward to the next grade school, Dawid
Love this technique. I don't think I can make it to grade school this week, but I think the obvious question would be: can you make a hue v sat curve in HSV space using this (or a similar) methodology? Another thing: often times we make adjustments to saturate a color more, but also to reduce its luminance. Right now, this requires making a similar adjustment on both the hue v sat and hue v lum curves. Is there a way we could tie those together into a hue v sat&lum curve?
Yes, you are on the right track. This is essentially what a chroma curve does. Very few tools can do this natively. For example, grossgrade has a pure chroma curve. Other programs, you need to set a node as composite mode 'color' with 'S' shape curves under a luma matte with opposite 'S' shape to work in a 1:1 fashion. We should make a dctl for this for sure. Another option is to incorporate the HCL color model directly into resolve so all the tools respond to chroma itself.
Yes! Yes! Yes! Only 1min into the video and i know this will be pure gold 💪💪💪 Question: Does combining HSL and HSV nodes for saturation in similar way have any benefits over only using only HSV?
Thanks for this! but as someone's already pointed out it would be good to have seen exactly what tools you were using... Any chance of reposting with the full screen of Davinci on? (probably not, but just in case..)
I've been using this method and realized just now that it introduces artifacts in shadows that the regular saturation knob does not (at similar sat levels).
If I have material recorded in camera in 8-bit (because I dont have internal 10-bit). Should I use "color transform tool" for node in davinci to change "output gamma" to cineon before color work or it is better to work without gamma transform, just in plain flattaned as possible footage?
Hi Cullen - amazing video yet again that has me thinking! I'm wondering, how does this process (particularly the targeted saturation adjustments you mentioned at the end) compare to adjusting saturation with Sat vs Sat curves? Thanks!
For starters, the sat v sat curve is presented as a horizontal line, so you can certainly make the mistake of making your mid saturation colors more saturated than your highly saturated colors, which can create artifacts. With the method presented in the video, you can ensure that more saturated objects will still be more saturated as long as your curve always has a nonnegative slope.
This is pretty cool I gotta try it out! One question though. Does saturating blue also increase contrast in a sun lit image? I hat that something like that happen to me when I graded and put more of blue in the mids of an image and couldn't figure out why it looked more contrasty. And I heard different colors have different densities. What's your take on it?
@@CullenKelly Yes, I have seen it yesterday! I felt that you had made that video because you had read my comment. Now that I read this answer, the reality is different hahaha but there is some kind of connection.
Thank you Cullen, that was amazing. Sadly when using your HSV node, I get very weird noisy violet or green artefacts in grey and white areas. Even when using it slightly to reduce saturation. Any Idea what I might be doing wrong?
Very informative video Cullen! Please move your talking head so that we can see the changes on the wheels for the next one :)
It would also be great to have a top down view of the mini panel & see what you’re doing
When he says spin gain wheel to the right, does it mean to move the color to the right? Or saturation to the right?
@@mustafakamal8608 It means the gain - the exposure tool, which now affects the saturation because of how the HSV node is set up.
I didn't get anything out of this, due to that exact issue. 🙂
This is the most beautiful treatment of saturation I've seen on the internet up to this date. Incredible tutorial.Cheers!

If I have material recorded in camera in 8-bit (because I dont have internal 10-bit). Should I use "color transform tool" for node in davinci to change "output gamma" to cineon before color work or it is better to work without gamma transform, just in plain flattaned as possible footage?
@@CullenKelly Thx, I will do it! :D
Hi Cullen - amazing video yet again that has me thinking!
I'm wondering, how does this process (particularly the targeted saturation adjustments you mentioned at the end) compare to adjusting saturation with Sat vs Sat curves?
Thanks!
For starters, the sat v sat curve is presented as a horizontal line, so you can certainly make the mistake of making your mid saturation colors more saturated than your highly saturated colors, which can create artifacts. With the method presented in the video, you can ensure that more saturated objects will still be more saturated as long as your curve always has a nonnegative slope.
@@CullenKelly Thanks Cullen - you explained the HSV vs HSL difference really well on the stream too which helped :)
This is pretty cool I gotta try it out! One question though. Does saturating blue also increase contrast in a sun lit image? I hat that something like that happen to me when I graded and put more of blue in the mids of an image and couldn't figure out why it looked more contrasty. And I heard different colors have different densities. What's your take on it?
This was Amazing!!! Cullen, could you make a video how to "DENOISE", please? That would be very helpful.
@@CullenKelly Yes, I have seen it yesterday! I felt that you had made that video because you had read my comment. Now that I read this answer, the reality is different hahaha but there is some kind of connection.
Thank you Cullen, that was amazing. Sadly when using your HSV node, I get very weird noisy violet or green artefacts in grey and white areas. Even when using it slightly to reduce saturation. Any Idea what I might be doing wrong?
