Join Chad Perkins for an in-depth discussion in this video Creating masks, part of Learning SpeedGrade CS6.
Oftentimes, when you're doing Color Grades, you don't want to work on the entire image, just a portion of it. And that's where masking can come in handy. So, down here at the bottom, there's actually a Mask tab. So, when I click on that, and I want to make sure to expand my interface by Clicking and Dragging this little grip indicator here. And that way, I can see all of my <ask controls. And we can just go ahead and quickly create basic shapes using the presets here, just like a circle, square or vignette. For right now, I'm just going to click on the circular mask, click that, and it is created for you. This is the mask, and then this little widget in the middle is kind of like the controller.
So, what I'm going to do is click on one of these points and expand it. Cuz I actually want to just kind of call out just her face, and correct just this area and make this kind of stand out a little bit more. So I'm going to click, and I can rearrange this however I want. And I can click and drag to increase the tension on that side, just like you would in Adobe Illustrator, or any other Bezier Curve Editing tool. Now, let me explain what this widget does, this is kind of interesting. If I click right here on this bottom part here, I will skew that particular point.
Actually, you want to select everything so I'm going to Click and Drag a marquee around all points, the entire mask is selected. And now if I do this it horizontally, skews the entire mask, I also vertically skew the entire mask. Actually, I want to be just like her face so I'm going to leave that there. I can also rotate it with this round part of the widget using the center point I can move this into position.
I could scale this horizontally using this right facing arrow. I could scale it vertically using the upwards facing arrow, and tweak this a little bit individual little points. And you might need to deselect and then select again in order to get that access to individual point there. And doesn't have to be perfect but that's good for right now. Also with this, actually I'll click and drag a marquee around these points just like the entire mask again. But I can scale up everything uniformly using this square here. And I could also feather the mask, which in this case is going to be really important, by going to this outer corner here.
So, I'm going to click and drag this out, and you can see that we have a second mask. And basically, it's going to fall off between these two masks. So, what we're going to do is we're going to brighten the area inside of this inner mask, and then everything outside of this outer mask will be unaffected. But between these two masks, there will be a gradual fall off between the affected area and the unaffected area. So with this basic mask setup, and actually I might click on this outer point and just kind of give that a better fall-off a little bit here. Now, what I'm going to do is go over to the Look area, and I'm going to make an adjustment.
Nothing's going to be different so far. I'm just going to brighten this up a little bit. A little bit in the gain, actually not so much in the gamma. That looks okay. Now, what I want to do is only apply this correction to her face and not to the entire image. So, what I'm going to do is go over to the Mask and Alpha area, these three buttons. And by defaults, Masks are turned off, so we need to turn them on. And so, this first button will do what we want it to do, will apply the grading adjustments we've made into that area. And this other button will apply the grade to outside the mask that will brighten everything outside of it.
We actually want to do this, which will apply the grading only inside of that shape there. So, if I press 0 on the numeric keypad, we could see before and the after. So that's the original, and that's with the adjustment that we've made. We might want to make that stick out just a little bit more and maybe we can even increase the temperature and just warm that up, just a little bit. And now her face really pops, really comes alive. Again, there's before and then after. Really makes it just kind of more three dimensional.
Another thing that we can do and actually this seems a little bright right here on our knuckle. So, I might go back to the Mask area and I might just click and drag this point, so we just have a little bit more of a falloff. Let me click on that inner point a little bit. And you might need to do this, as there are areas where the mask is kind of obvious, and we don't want it to be obvious at all. So, go back to the Look area, here's another thing we can do. I'm going to select this layer, and I'm going to click on this button right here. This will duplicate the current layer. So, what we can do now is do the opposite.
And we can change it so that the mask applies only to everything else. So, what I'm going to do here is do the opposite. This is kind of an extreme example here, but I'll click the temperature swatch so that this isn't warm. And we'll take the gamma and the gain, the opposite direction. You'll see what it's doing is that it's darkening everything behind her. So, that makes her head stick out even more. It's kind of a little ridiculous. It looks like her head's like 20 feet in front of her body in this case, but I just wanted to show you what's possible.
Again, here's before darkening the background and then after darkening the background. And here's the original, and then here is the corrected version, with the brightened face and the darkened background. Again, this is a little bit too much. But we could always go back to our opacity adjustment for each layer, and dial it back. So maybe, we'll do about 50%, somewhere in that range, for each of these. Do, do, do, do. And there we go.
And now, we have a much more balanced image. There's the before and after we darken the background and brighten her face with masks. We have that. So, Masks again are a great way to isolate parts of the image and just work on those.
