Color Range Command 2

 

Okay, we’re going to continue, folks, to colorize this Porsche by cleaning up the layer mask that was created in our lesson on the Color Range command. And what our layer mask does, when used in conjunction with an adjustment layer is, wherever you see white, folks, it’s allowing that adjustment layer effect through to the background layer, in this case. Okay, wherever it’s black, it’s blocking that effect. Let me show you what happens when I delete this layer mask. Now it’s letting the entire Hue/Saturation adjustment layer affect the background layer.

Let me delete, hit CTRL + Z to back up a step. Now let me show you this layer mask in the actual document window by holding down the ALT key and clicking on it, right here. There you go. Now you are looking at the layer mask as a grayscale image. Okay, the same way you would be looking at it as an alpha channel in the channels palette.

Now what we have to do to clean up this colorization is get rid of these partially selected pixels. Let me zoom in by holding the CTRL key and the SPACEBAR at the same time and then marqueeing around an area that I want to doom into.

Okay, these partially selected pixels here…

[NOTE: Partially selected pixels have a transparency value applied to them. They occur when they are not an exact match for a color you selected using the color range eyedropper, but they do fall into the range set with the fuzziness value.]

…are letting through some of the Hue/Saturation adjustment layer but not all of it. It’s based on 256 layers of transparency. If you remember in the Color Range lesson, that command will partially select pixels and you can see these dirty pixels here were partially selected; that’s why they are grey.

Wherever you see black, those are 100% DESELECTED pixels, wherever you see white, those are 100% SELECTED pixels. The grey pixels or dirty pixels are not letting the full effect of this Hue/Saturation adjustment layer through to the background. So let’s clean them up. And we do that, folks, by painting in black or white, okay? What you need to do is get the Brush tool, alright, and then make sure you have white as your foreground color, black as your background color. And if you don’t, hit the D key on the keyboard, for Default, and that will select your default colors. And then let’s start out by painting white. Vinyl Banners by Experts

I am going to increase my brush size by hitting the right bracket ] key on the keyboard, and then, I am just going to paint white here. And when I am doing that, I am allowing more of the adjustment layer to affect the background layer.

Now you don’t have to work in this grayscale image, let me show you. Sometimes it’s the easiest. Whoops. CTRL + Z. If you go to far, you can just hit CTRL + Z and back up a step. You can also work… Hold down the ALT key, and click right here.

You can also work in the image itself, okay, and watch it be revealed as you work.Okay? Now right here, we are going to need to paint in some black, so let’s change the foreground color to black by hitting X on the keyboard. Alright? Lower our brush size by hitting the left bracket [ key and then I paint in some black, that’s what we are doing, we’re painting in some black here. I’ll show you.

You see? Go back and forth and just work on your image, by switching the foreground and background colors and just painting, painting black and painting white. Changing your brush size, going back and forth, and cleaning up your image. Okay, I am going to finish working on this and I will see you in just a moment. Okay folks, about three minutes have elapsed. And I spent that time painting in black and white, working on the layer mask. Here it is, you can see I got rid of all those dirty grey pixels, and I am letting all of that Hue/Saturation layer, where the Porsche exists, through, to colorize that portion of the background layer. And there you go.
