Using Curves and Vs Curves In DaVinci Resolve 15

today we take a look at an advanced way of using curves as well as all of the versus curves [Music] all right so jumping in here we have our first shot let's close this up we have our first shot here and we kind of have an overcast day there isn't a ton of detail in the sky here there isn't really much to see the majority of this is gray and kind of flat looking as we progress through the shot we're sort of getting that same thing where it's just gray there's a little bit of blue in here but for the most part there isn't much detail throughout this shot when it comes to the sky if we take a look over here traditionally it starts on key frames but you can click this little button to see your scopes and we can actually see the information for each of the channels and what we'll notice is that right here along the top nothing's actually touching it it's right right below it so we have some some space that we can work with this because all of this isn't clipped clipped is when you have your values pushed to the top like this and then you just have a solid color but currently it's not a solid color there is detail in here it's just very hard to see because there isn't much contrast between the high points that are bright and then the not so bright lower points so there is some detail in here we just have to manipulate that so how we would do that is we traditionally use curves there are a couple of different ways of doing this but we would use curves where we would you know make a modified like little S curve something like this where we get more contrast II looking more of a contrast II shot but typically we would normally put at the higher end we would put one and we lift this and all we're doing is just really compressing that so we don't really want to do that if we pulled it down we can pull it down and get more of this but we're also dropping a lot of this mid-tone detail which is this barn here so how would we go about doing this and not have it affect the majority of this other stuff but have it affect the sky what we could do is we could use qualifiers so qualifiers you can pick a value so the eyedropper I can click right here and now we have a value with some red lower saturation levels and a medium high amount of luminance which is your brightness so if I click on this little button so I can see what I have selected I have the barn selected so traditionally you would pick a qualifier and then you'd be able to modify that qualifier you know to your liking so I can modify this barn and get it to look a different color we can take that sort of approach to this but we could use just the luminance value to grab just the sky so we can just modify just the sky itself so I turned off the hue and the saturation here and then all we have to do is just move up this low level till we get to a point where we don't have the majority of this building in here anymore as you can see when we move it up all the stuff that's in gray won't be affected by this node anymore so we are just lifting this up a bit and we're getting rid of most of this one thing that you have to watch here is I have a tree over here if I lift this too high what happens is that tree becomes like a blob so we don't really want to do that what we could do instead is we can lift or we can move this softness so that we start to soften out around a lot of that stuff we can add a bit more softness and we can soften out around that stuff and then all of these like mid grays and stuff they'll be affected but they just won't be affected as much we can do just something like that now if we come into our curves all we're going to be affecting is that sky so currently our top point is up here at the top we can pick somewhere right below here and then pull this down and it should separate the majority of this information here so if I just grab here and I pull we're kind of separating this and then we can put like a kind of like modified s-curve in here and if you see over in here now we're getting a lot more detail in the clouds it's a it's a little bit much here but you get you're getting the idea of how this works additionally something else that you could do is you could use your contrast setting down here and they just move your pivot so how a pivot works is a contrast is affecting this whole thing and our middle point is right here the pivot is where that middle point is so if we would move that and that pivot to something else what you'll notice is now the pivot moved up and it started to separate this data up here so we're sort of getting that same thing and it's not so intense as when we were using the curves adjustment here so that's kind of another way of doing this and we don't have the blotchy stuff that was over here that it's moving everything kind of uniformly so now we have the ability to affect the sky here we could change its color we if we want it to we get to come into our temperature and we can adjust the temperature make it warm or cooler you know and so on that's one way of working to modify your curves is by using a qualifier to select just an area and then we can use our curves adjustment so let's go on to another shot here so this shot is just some I just wanted to grab this shot quick cut it's just a bunch of color if I boost up the saturation what we can see here is we have a reddish color and a blue color that's coming through some of these glass chess pieces so if we come up here to our curves we have a our customs curves what we've been using and most people understand curves as being these curves that you can adjust the red green and blue channels or you can combine them and effect them all together or just click Y and then just affect luminance so if we drop down to let's say hue verse hue what you can do is you can take a a color value and you can change it into a different color value so here is our color wheel if we wanted to take a red and make it blue we could just move those colors around you know if you were to grab your offset wheel and move think to the blue you're affecting everything around as well but we can with the hubris hue we can pick just a color value so we clicked right here with our qualifier selected and when you go into these curves it's automatically selected and once you select a color then it's going to pick that color and a little bit to the left and to the right of it and now right here the outline is where that color resides we can move this up or down and we can adjust that particular color now there's a bit here that is kind of looking a little bad if you wanted to add a bit more of it in you could just slide this over and now we're getting a little bit better with the gradient here when you're moving these so try to reset them it's the one that's active is always the one that is the outline of the circle you could just simply click down here and it'll reset over on the curves if you want it to reset or get something to come back you could just hold the alt and then it would snap it would snap back there so and as well if we were to move this we could always snap but yeah that's how that would work now going back over into our Huber's you obviously this doesn't look very good so how could we use this hubris hue in an actual shot so if we come over to an actual shot this was shot with a Sony camera and for some reason tungsten lights like these Edison bulbs they always they don't really look that great there's it's a weird yellow it looks kind of like a sick yellow I don't know why it is what it is but we can modify this and it's a very slight modification all we want to do is just add a little bit of like an orange e reddish into here and it'll really make this look a lot better so if we were to click somewhere in here to get a yellow and then we could just sip just modify this just so slightly I would say something just like that and then just bring this down a little bit and add a little bit of red into here and we will bring this end point down and just clicking here we'll have a go to zero and now we're kind of getting somewhere there is a bit more it's kind of milky so let's just add another node in here just drop down our value a little bit and get kind of a little closer to where we probably want to be I would say something something like that okay so now we're sort of getting somewhere so where we were that gross yellow to kind of where we're at now everything's looking a little bit better there's a little bit of extra red in some of the areas as you'll see up here there's a little bit of red I don't know if that'll show through YouTube but there's a little bit of red up here an easy way to show this is if we were to what you see on YouTube a lot is a lot of people say okay you know in your mids and highs we're gonna push them red or orange and then we're going to take our shadows and we're gonna cool them down by bringing them in to Blues in science so if we were to bring this down to Blues and science like they say to doing those what ends up happening is this is supposed to be black but it's not it's a blue and you get a lot of these like color casts that personally I can notice and I don't think that looks very appealing so what I would do to not have that amateurish look there is just take a look into a shadow any shadow anywhere in your house wherever it may be and what you'll notice is where it where things are lit they have a good level of saturation and then as they go into the shadows what ends up happening is that saturation that brightness and color starts to diminish it doesn't turn blue it's just diminishing now if you're outside and you have a warm Sun beating on the side of one mountain and the other side there isn't a Sun and then you have like some type of like atmosphere diffusion off into the distance obviously the other side is going to be a little more on the blue-ish side but we're not in we're not outside here we're inside we have black TV screens and a speaker over here as well as her shirt and their work we have this blue tone that's being added to a lot of this so we would want to get rid of that obviously and then back in here this is starting to look purple because we had red it's red bricks we're adding blue in there it's a darker value so it's adding that blue on there so we're also getting purple back here so let's get rid of some of that if we come into our luminous for saturation or we're taking as luminance levels and we're reducing the saturation for this so we could just click down here and this is going to give you a good starting point for your shadows and where they fall off we could just bring down some of the saturation and a lot of this and what you'll notice is that in our screen we start to lose that saturation actually let's make this funny another note so we can turn this on and off but what you'll see is as we pull this down you'll start to reduce the saturation over here you can also click there and you can get where that value Falls so you could bring this down you don't want to go overkill on this because if there is some luminance in an area you are gonna have some color so just don't go oh you know crazy with it but that's the overall idea a lot of the darker values you're gonna want to not really have much color in them because they're not being lit up by anything to represent that color but there will be some color in things that are in shadows just not much so that is a way as you can see the blue here and now it's a black and it's looking a bit better as well as you know everything else his hair is it blue anymore it's represented by black which is I would think that someone that has black hair isn't going to go and get it dyed for a shoot and it is still black okay so that is one way of using the luminance for saturation we talked about the hue verse hue now let's go into how Q verse saturation works now to make if you're if you're if you've just jumping into DaVinci resolving you not you don't understand how I'm making these other nodes you can just simply come up to Wow where the hell is it you can come up to color and that nodes and then add node here it's just alt s you can also come over here you can click over here add node and then you can pick a node to add okay so now that I am now I have a clean node that I'm gonna be adding here there hue ver saturation it's just is simply what it is you can pick a color and you can make it more saturated if you want at the bottle or her shirt so let's just pick her shirt and now I can add more saturation into her shirt as you can see here we're just adding more saturation of the things and as you can see everything else that is a similar value is going crazy so we could just simply take a mask or also known as a power window and then just select an area that you want to have affected by that particular selection and then there we go now we have just her shirt is affected by it and it's showing that red value we could also change the color of it if we want it to but that's the idea here a lot of times where I personally use this is let's say I have a shot of a park and there is a stop sign in the corner but I really want to get right saturated grass that looks great as well as a nice blue sky but then we have a stop sign there that is just blazingly bright red we can tone down that red a little bit by picking that red dropping down that saturation and then we have a shot that looks a little bit better and that stop sign or if you're looking at this you can see boom look at how bright that red shirt is you can bring things back into your grade so if you have something that's really saturated you can bring it back into your grade so that it looks a little bit better the next thing that we have here is Satmar set so the idea what's at Birth set that I personally use it for is if I'm trying to recreate a look or I'm trying to recreate like a film look or something of that nature what ends up happening with a lot of film stuff is you don't really have saturation levels that are really bright you do have a good saturation level across everything but it's not really bright so you want to take you know all of your saturation and you want to bring it up but you're gonna have if you just move the saturation curve it's gonna move everything so you're gonna have a couple of pieces of saturation that are gonna move up faster and if you can see over here because we have her shirt that's so saturated this is the red if you don't know how a vector scopes work it's pretty much set up the same way as a color wheel we have red magenta blue cyan green and yellow same exact way is here and then we have these little pieces I just turn this up to 2x so that we can see it a bit better we can see these pieces that are out and how bright they are and you can see the majority of this shot is kind of on the red side and it's represented here let's say we wanted to tone all of the really out the outliers I always call this we want to tone those back we get simply you set or set and it's taking one saturation value and then you can manipulate it to be something else so we could take the brighter end here and we could tone this down and what you'll see is we're manipulating here or bringing down that brighter value you see that and I think her shirt actually comes in a little bit further in and it does we can tone this back a bit to you know kind of come back into the toll range of the rest of the shot and not have it be that really bright value and then we can have everything else the same and we just brought back so we pretty much eliminated that here but we didn't have to use we didn't have to specify it just being you know a very particular part of the shot we can bring the tonal values of the whole shot down to to match everything else or if you're going for a film stock particular film stuff you can tone it down to whatever that film stock would be recorded as so that's kind of how I personally use the sat verse at so yeah I think that's pretty much it on how I use curves in DaVinci if you have experience using curves and you use them in a unique way let me know in the comments and I think that's pretty much it for this one again my name is Sharon thanks for watching [Music] [Music]
