Now, the problem with this technique, the down side is that we have transformed all colors inside the image. So in other words, we did not just change the yellow boards to red, we also change every other color inside the image to some different color.
So for example, if I undo the modifications, you can see that this plastic underneath the boards is sort of this dull brown color. And then afterwards, it changes to kind of a dull purple color instead.
Okay so, it does not happen to matter them much in terms of this image because yellow boards are really all we see. We do not really care or notice what the color of the plastic is underneath. But, it change as well. What if we do care about the other colors inside the image? Well, we have to use a different technique.
To reveal this wonderful technique and it is truly wonderful folks, go ahead and close this image, yellowstats, I am going to click no and behind here, I have another image open. It is called girlinvioletphotospin.jpeg. It is also inside the Lesson 6 folder, inside the Part 1 folder, and this image happens to hale from total trainings favorite stock photo agency, which is photo spin. This is more of a traditional stock photo agency, photographs by professional and it shows. And this is a lovely, lovely wonderful photograph.
Now, I do not want to correct the colors inside this image because the colors are fantastical, but all I want to do is I want to change this little girl’s shirt from purple to some other color, from violet to something else. Without changing the colors in their face or her glasses or the green background or anything else, how do I go about doing such a thing?
Well, it turns out we go that very same command, hue saturation.
So, what I want you to do just so that we can see a new technique here, I want you to replay the last hue saturation you just got done applying. Let me explain what I am talking about.
If you go to the image menu and you choose adjustments and you choose hue saturation again, or you press Ctrl U, the keyboard shortcut or command U on the Mac. You just bring up the hue saturation dialog box from its default starting point. So, no changes have been made. However, you can re-apply the last color adjustment, you just got done applying. This is true of many of the color adjustments inside Photoshop. By choosing the command with the Alt key down, under Windows or the Option key on the Mac, press and hold Alt or Option and you would choose the command, okay? So that is one way to do it.
Or, you can just take advantage of the modified keyboard shortcut, Ctrl Alt U or Command Option U, and that will replay your last color adjustment, that will bring up the hue saturation dialog box complete with the last color settings you applied.
And only reason I am doing this other than to show you a nifty new technique just so you know is so that you can see how this specific adjustment affected all colors inside the image. So in this case, it changes her shirt to blue from violet to blue, but it also changes her face from a natural healthy sort of yellowish, orangesh tone, which is where all of our face tone reside no matter what you are luminosity values, no matter how light or dark you are. And it changes her to this strange sort of magenta creature, which nobody falls inside that range. And if we increase the saturation value, it is even more obviously wrong than it was before.
So, how do we go about isolating just her shirt, well, turns out we can do that from inside the hue saturation dialog box and we can do it splendidly.
First thing I want you to do, assuming that you have done what I have done so far, you brought up your last changes, I want you to restore default values, and you can do that by just changing the hue and saturation values to zero and zero and of course, zero for lightness if you want it too. You can do it manually in other words. You could cancel out and re-choose the command. But here is the best way to do it, another technique that works inside lots of dialog boxes.
