Tone and Colour Correction

Okay, So so far we talked about what we've incidentally talked about color. When we've been talking about currents because we're increasing the contrast, increase the saturation. But new Let's switch Teoh Toning folder and no, don't go with first Fire, which is Lab will come back to lab later. Hopefully go with T c. I won't. And let's look at a few different tools we've got for adjusting images, thistles, A shot off. Um, I forget what the rights called Blackpool Pleasure Beach to we live in when we're in England on a So what would you want to do to this? This kind of occurs there active. Just just got a little bit more contrast. Make it a little bit brighter. So we'll leave That turned on. What would you like to do in terms of color? Increase the color intensity more intense. And she is the color yet What color would you like to pay? There's a pink I showed up with over the pink jokes. What color would you like it to be? What could we do you like to see purporting? Purple? Purple's kin...

d of pink, isn't it? Yeah. You see, you knew had Gunboat you go in the pink room, right? We've got the channel mixer here on. We mentioned earlier we were using the Channel mixer for on Black my conversions. But you can independently modify these channels. It's what I've done here. Haven't changed the Red Channel. I have changed the Green Channel. I haven't changed the Blue Channel. That's what I've done in the Green Channel is I've lowered the contribution of Green Channel 74%. So why is it gone purple? No, I wanna show you something. If you're using a Mac computer Ondas to color pictures in fact, shop his eyes of the adobe one, which is kind of a square grid where you can change all the values. I'm is kind of useful to look at the apple color picker for a minute. So it's gonna power, folks, I did something with green. So what's that? The other side of green being comfortable magenta. So when we're thinking about color, kind of, if you can get this color wheel to stick in your head, you'll find it's really useful for the rest of the afternoon, or at least for the next anyone on or 20 minutes and I have along with tights. So if you think about the primary colors, we've got red here green. They're blue, Ran the wheel. In between them, we have the second colors. So it goes red, yellow, green, cyan, blue, magenta. If we look across the wheel, you'll see those opposites here. So the opposite of green magenta, the opposite of blue is yellow. Ready Science? Yeah. If you forget it, just share and will come back to you. Wanna jot it down? It's kind of important to remember those for a lot of tools we're using. So if I take some of the green away from the Green Channel, it's gonna go to its opposite. So the more I do that, the more magenta is gonna get. If I increase the mail, it's gonna go green. So the channel mixes quite, you know, we can shift. It kind of starts off reason. The neutral weaken shifted towards green weaken shifted towards if I wanted to make it yellow. What channel? We don't need to be admitting who were clear. Channel which direction we're gonna push the slider down. Game well left. There you go. So we can go yellow by dragnet in that direction. We could go blue, my dragnet in that direction. By the same token, if I switched to the Red Channel. If I go up, it's gonna go red. What kind of pinky? Red. But if I go left, it's gonna go. What? Yeah. Hey, Scion. So we kind of start with this neutral turn the right lettering off. Kind of neutral image on you can pick any color that you like. We've done the channels independently. You can mix the channels as well. So we revolted once the time. But you can also to it a time. Yeah, that makes sense When it did happen quite quickly. Quite easy. An easier one channel. The Channel mixer is a bit complicated, cause this idea of mixing channels together seems a bit confusing. I'm so another one you can use his color balance tool. Now, this operates slightly differently. We've got three buttons on top shadows, midterms and highlights. And then we've got a load of sliders down here. So I want to alter the midterm values and write more. Scion kind of do that. I want to read it. I could do that same again. I can do pink magenta. I could go green. I could go yellow. Go blue, you doing? You're doing exactly the same thing here, but with a different you kind of just skewing the color in a particular direction with with the Colorados to Although I could independent change the highlights so we could have some yellow highlights and I could go back to the mid tones and have some say in mid tens. I kind of got a warm yellow for the highlights on a sign from it turns. Um, preserve Luminosity, sometimes quite useful, is welcome. Kind of when that's turned on. We're adding a lot of color in, so we're making the image a bit bright. So sometimes turning that off if using the color. But it still works well. I'm kind of going quite quickly through these, but simply because I want to give you a feel for the scope of the different tools. Does that kind of makes sense So far? Yes, so that's channel mix of color Balance Channel Mixer is kind of an overall adjustment, so we kind of went blue. But we're going blue across the image on, you know, become controlling. It's an independently color bands is slightly more sophisticated because it allows us to control the shadows in the midterms and highlights separately. But in kind of exactly the same way this time you've got your color pairs. So much is not for you. If you forget the red Cyan, Pam, gentle and green and yellow and blue. Okay, so that's two tools you can use for turning images. At this stage. It's worth pointing out that we're working on a very blinding. It's almost black and white, so I kind of don't want confusion issue. I'm gonna show you kind of throwing throwing cones that things. Another tool is a selective color, too. Anyone played around with selective Kotal? I'm afraid of it because I don't like selective color you don't like in wedding right now. It's got nothing to do with that. That's okay. So you've been afraid of it for the wrong reasons, right? When you work with color image on, you got a whole range of controls here for difference channels. One way of thinking about the selective color tool that might help you make a bit more sense it. Everyone understands how an inkjet printer works kind of a simple inkjet printer. What color inks deporting an inkjet printer? Yeah, So for a sing a simple four color printer, it's cyan, yellow, magenta and black on you make any color out a combination of them. This is pretty much what the selective color told dots. So let's go to skip the colors for the time being will come back to those when working real image with more color. If you go to the neutrals on what kind of alternate already, So let's let's reset that. If I want to change the in cabal Unz for the neutrals in this image, I can add in some magenta if I want to make them darker, I can't and some black I want to make a lighter intake and some black. So the neutrals, it's like, How would you prince the neutrals in an image using inkjet printer, you would vary the combination cyan, magenta, yellow, black make to create a color on densities, whereas densities darkness. It's that kind of makes sense. If anything of it. Training for reasons that you're high, figure out OK, so again you can kind of mix these colors up on effective. You could make any color at all because this is what inject princes. Do you know there's no range of colors you can't reproduce in a new contract, so it could have kind of greeny scion. We could make it a bit more green by adding some yellow. We could make it more signed by taking out yellow, and you kind of have to get a feel for human. These colors go together, but effectively, with a neutral image like this, you can turn it in anywhere you like. And again I could go to the highlights and say, Okay, let's make the highlights a little bit more yellow so loud in some yards the highlights take out some of science. That's kind of a subtle effect. I'm not sure that shop online kind of new. We've got this kind of yellow glow around the brunt spot. Kind of that kind of makes sense. Quick question from Tatiana. Could you touch on the relative and absolute buttons of the selective color tool? Yeah, If you select absolute with selective color, it'll you see quite weird things happen. So now if we're looking at the whites and we switched absolute, the whites and become extremely yellow. I don't understand the maths of this, but it's relative. If you leave, relative selected its relative to its current brightness, so because it's very brightened whites down here. If you had yellow toe white, it just stays white pretty much if you want an absolute value so that this kind of disregards the fact that it's very bright. You can then add more color, typically for a subtle effect. You're gonna be leaving it set to relative because kind of that kind of looks wrong to me when I don't like that. So it kind of depends how you want toe and the colors of the image. Absolutely well, it's kind of like just throwing the color at it relative. It takes the brightness into account and uses that term. How much college kind of makes sense. The commission. Stevensville. Excellent. Okay, on right restriction of the revision. You before Actually, no. Let's stick with that for a second. Let's add another curse adjustment lap, so I back back with my favorite tool again. Now, when we've used the curse tool, we've stopped with the RGB on. If you look at this little drop down menu, at the top here. You'll see you've got red green on blue. Yep. So I switched to read. You see the curve changes to read now without doing anything. If I had a control point in the middle and drank this slider towards not slide of control point towards the top left, What color is going to appear? That red wine usually only record channel. I'm going towards the top left. I would make for the reds brighter. So as we got cross, you can see I'm kind of adding red if I drank it the other way. What color is it gonna go? Who? It's blue and, well, visually. Yes. Technically know what's the opposite of red color science. Yeah. So even got science. If you wanted to go blue, you'd be kind of dragging the blue slider to make a girl blue. What's it gonna go for it? The other way. Yellow yellow? Yeah. Cool. On the same was green Weaken. Do the green and we could go back to our kind of pink color here. Now, one of the things we can do with the curse tool is we were talking about telling the highlights before. If I want to and yellow to the whites. During that I still ended when his bright white stone here. What would I need to do to add yellow to the highlights? How could I do that? Using curve, Go to the highlight End of and go where with it Down. Well, don't. Absolutely. Yes. If you go that way, it's kind of moving the white point along. But I go Damn, I'm dropping the white point for the blue curve, which means I'm adding yellow by taking blue ales and I didn't yellow in that makes sense. We may get some questions about that one, because kind of moving white points down curves is a little bit different. But I can also do something Still change the shape of this curve. So what I what? I don't know. In terms of the blue again, uh, where that where that point is, would be shadows. You're adding. Yet if we're looking within section line again on anything to the left of intersection line, we're ending in. That was in this case to the shadows in the midterms were adding blue, but to the highlights were brought this dance and red and yellow. So if I kind of just rather reset it, let's just start again because we have the green curve active there as well, so I can pull this day that adds, yellow across the image, pulling out. So there we got kind of split time. The image we've added yellow to the highlights on blue in the shadows, turning on and off. You can see it's not adding a great deal in blue when it's having some, but it is having quite a lot in yellow. Okay, that makes sense. Yeah, right. We're kind of thrown color at an image that didn't have much to start with. And this doesn't really time to my point about adding character. Anything else? It's just kind of a way of toning images that quite stark and like color. So the image we looked at yesterday off the pole, in the wires in salt, it is another one of the pink ones here and come in bright purple tone with through on Onda kind room, which we don't want one of those wives. So let's look at an image where it's a little bit more subtle. I'm on which ones we go here This is kind of my favorite image for demonstrating color and this waas I think you'd find in there. Sorry T c I to Right. So what? What time? What time of day was this shot? What's going to speculate? Name Like finding in fact Evening. Yeah. Yeah. Sun's going do Okay. What time of day was it? Shot? You now have changed it mid afternoon. Possibly enough to new. Uh, does that change the feeling of the image again so we can make it colder? Weaken Really warming up so we can have a nice sunset? Uh, got cold in that way, we get warmer. We change it that way. What is the color doing? What? What is the color important in this image for the other for the other image we just looked at. It's kind of a graphic thing. We're just creating a graphic. We know we're not really changing the move particular. What can we do with this image? What is the color do? What message does it put across? Well, it conveys a different emotion. I mean, the color temperature, sunrise, sunset. It's a different emotion, then warmer versus the colder. So yeah, yeah, So If you look at this picture here, you've got these two figures here, so kind of what's not invited things. Guy to me kind of looks a little bit hunched over. It's a bit cold if we go for this one. The guy you know, even though it's a tiny little speck in the distance, it kind of looks like a struggling along in some light, so you can change the whole feel of the image. Now these 1st 2 it's a selective color, so let's take a look at what we did to make it colder. So with the previous image, because it no much color to work with. We looked at the highlights on some of the whites and neutrals, but this time we can take a look at altering individual color ranges. So for the Reds, what I've done is if I didn't scion, taking out magenta and taking out the yellow so we reset likes their default values. Your kind of you'll see the red come back in again, so not a huge difference you get. You get the red effect of that for Let's start, let's start from scratch again. Let's start with a new selective color adjustment because we want to take the Red Aims. We want a cold a field. So we're gonna put Sion in. I'm gonna tighten Mogens from the L A. Rams, so I kind of get rid. We get rid of the Reds. The Reds kind of gonna image if you go to the year lives. Now, if one of those colder technique yellow text in the region Three Italians science. So we just to changes there. There's the image before we ought to the Reds and yellows. And there's the image when we kind of it's kind of equivalent to just decent correcting the reds in your lives. So much cold field. It's that kind of makes sense. Yeah. So what happened with this one? If we if we go back to this one what changes were made there without looking speculate about when you can see the 1st You see what's happened to the Reds? The reds? The science taken there, Lots more magenta supporting and lots more Yellow is pouring. What else have I changed? I haven't made changes to the yellows. You think Turn it off again? Kind of what? This is a tool for playing around with You kind of need to fiddle around with this one. To be, Kev is suggesting saturation. Have you played around with that, um, effects of this study? We haven't changed it all. We're just changing colors. Scott Woods. Did you get rid of the blues? Let's have a look. What? We just the blues. Um no change to the blues. Any other guesses changed science. All right, no change the greens on They changed. The magenta is I think you changed the l a. The whites a little bit the neutrals. So the neutrals have being changed. Eso I've added some yellow neutrals to take the name and see the difference that night drug that across I could go blue and I could go yellow. It's kind of the neutrals of the mid tens. Um, in terms of yellows, what I've done is taken science, adding some magenta and yellow kind of we just one adjustment we've gone from. In fact, I think this was taken. It's kind of late afternoon in winter, so it's not too late in terms of time, but kind of the sun's about to go down for a filing. Five. Tell us on camera Ditech. So you have the first of February 2006 at 23 in the afternoon, so the sun hasn't quite come down, but it is. Winter is quite cold, but if you look at that one, you know, this is kind of almost a different time of year. There isn't never mind a different time of day. It's got a completely different feel to it now. There's two reasons. I think this is a useful technique on, I think amongst yourselves now who would like to volunteer and come up and play with these tools on one of the images they shot. I don't want anybody in the spotlight don't come up, but maybe someone who hasn't come before So have a poll interviewing volunteer on what kind of go through some of these tools. There's two reasons it's important. One is. You can do things like this. You can fundamentally change the feel of an image. Um, so if you start out with something like this is people walking along a bench? The emotional content is images don't have emotional content images, Redford for emotional content or you and emotional content so kind of when I teach this with big groups is quite interesting. So I got a group of 16 people on 18 men and 18 women on. I let everybody loose in the area, so just just play around with selective color. It'll until you've got an image that you're happy with. Kind of. How would you think? Just what would you say would be the gender split in terms of appearance of the image? Would you expect to be well, every single time I go? This photo with this'll? How would you expect? Would you expect to be a difference between him raining women? Typical processes? I would. Yeah, I would expect women to go more towards the warmer versus men going more towards the colder. And it does invariably. Not everybody it's not. It's not 88 split, but at least five or six men come out with quite a cold image. At least five or six women come up with kind of either something that looks like this are kind of the more kind of pinky image, but kind of a warmer, more nurturing tack of image. So it's kind of interesting when you do it in a group because it makes it makes people think Why did I do that? It looks good to me. But why did I do it and why? Why have I done the same as all the other way blacks ago if I was interested in the last group in it when the blokes have gone pink. And as I started explaining, I could see thinking about this is well, I'm changing a bit and it gone pink and switched to blue before anybody notices. Is that that was kind of interesting. I'm so you can change, fundamentally change the mood of a picture. But it comes back to what I was saying as well about digital cameras. All ship, that same image. And there is variation on but not huge amounts. And you kind of want to make a software change out of subtle tone. I am so for me, I'd be looking at a curve with this one. Maybe. All right. Kind of one of my favorites. I mentioned yesterday kind of adding a bit yellow to the highlights on kind of punching up the blues a bit, retaining the blues in the shadows. So I'm looking at something like that on, then maybe just a touch. More contrast. That would kind of be a typical change for me. What kind of hat? Look that I kind of like that kind of signature time for May. You're free to do anything you like.
