In the previous movie, we talked about color correcting skin by the numbers. Well, in this movie we are actually going to do it. We are going to get our hands dirty. We are going to learn how this actually works. We are going to be working on this file robin.psd. You can find it in Chapter-20 folder, sub-folder skin by the numbers, go and open that one up in Photoshop by double- clicking it in a Bridge, press F to get a Full Screen View mode and then Spacebar to re-position the image. Now the first thing that we need to do is select the Eyedropper tool. Press I in your keyboard. We need to change our sample size to something other then Point Sample, the higher the resolution, the higher the averaging. This is pretty low res of 5/5 will work fine. Now navigate to your Window pulldown menu, choose Info and that will open up the Info panel. Now this current panel is docked. Because of our default preferences it's going to auto close when I go to my adjustment layer, I do not want that. So I'm going to click and drag this out then I'm going to open up the Info panel and I'm going to click and drag that Tab out so it's free floating, then I'll close my other tabs here, Histogram and Navigation, so I just have a free floating Info panel.
All right, great. Well, you can see that I have already set a point for you on this document. I'm going to remove that so we can talk about how we would add that point. Well, here is what you do. You hold down to Shift key and you click on a little area. Next you go to your Info panel, change it from RGB to CMYK. All right, when I look at those numbers I say Okay, are my Magenta and Yellow equal? No, problem. Is Cyan 1/3- 1/5 of the Magenta or Yellow? No, another problem. So let's fix that. All right, well, down here in the layers panel you will notice we have the original image and then we have the retouch file and the retouch file looks better. If you are interested you can get more information about retouching, I have two titles on retouching, you can check those out in the lynda.com library. Yet the point here is not retouching, the point here is color correction. So, click in our top most layer. Then we will click on the icon to create a Curves adjustment and we need to work on this Yellow and Magenta relationship. Yellow needs to come up, so I'm going to select the Blue Yellow channel, grab the Target Adjustment tool, hover over this and then click and drag. Here what is going to happen when you click and drag, you are going to forget which way to go? So you drag one way, then you will drag the other, but you will quickly teach yourself which way you need to go. So I drag up. Okay my Yellow percentage went down. That is not good. I need to drag down. I just need to bring that percentage a little bit above the Magenta. Okay, well, the image is looking better already before and after.
Well, my Cyan amount is too high, so I'm going to go ahead and go to my Red channel, Target Adjustment tool still selected, hover over this and keep in mind, what I'm trying to do is lower these values, so that if I multiply this number by 3 or 5, it equals or fits within that range. 3 times 6 is 18, 5 times 6 is 30, well, I'm close. But when I increase the Red I also modified my Yellow down here, so I need to fix that, go back to that Blue Yellow channel and here what I'm going to do is simply increase that because we remember, right? Yellow always needs to either be equal or a little bit higher than Magenta, so I lower the Magenta, go to that Green Magenta channel, click and drag that down just so it's a touch below that. Now 3 times 7 is 21, Cyan is too high, click on the Red Cyan channel and I'm going to click and drag this down.
One of the things you will notice in here is there is an interplay with these numbers, it's kind of like cooking or kind of like a recipe, little bit of this, little bit of that, little bit of this, little bit of that, right, you go back and forth. Now this image 3 times 5 is 15, 5 times 5 is 25, so that number is right in the range. Now I could change it little bit, I could go up point percentage point, let's do that so I'll go ahead and go up to save the 6 or so. I think 6 would look good and then select our before and after. Here is our before and then after, you know what the skin tone is now Color Correct.
Now keep in mind this is just a recipe, just a starting point, we can make further modifications from here. You also can swing your color at one way or the other. Yet all that been said, this recipe will begin to help us to get color correct images and more importantly color correct skin tones. Okay, well, in the next few movies, let's apply this knowledge that we now have to a few other images, so we can really see how this stuff all actually works.
