Hi! This is Mama Shan with another Green Screen Series Video. And in this video tutorial we are going to extract this lady from the green screen. And there is a different method to use when you have a lot of hair. It is very easy and you have a lot of choices to make when you are doing it on a simple subject like the gentlemen that we did that basically has a very close crop haircut. But when you have hair, the approach is a little different. We are still going to create a layer mask but we are going to use the Background Eraser Tool.
So the first thing that we have to do in order to preserve a copy to mask is to duplicate the background. So on a PC, you would hit Ctrl+J, Macintosh that would be Command J, and that will give us layer one. Once that is done, you can shut the visibility icon after the background layer. Make sure you are highlighted on layer one, and then come over to your tool bar and click and hold on the Eraser Tool. The background eraser is the second tool that has the scissors icon on top of it.
Then look up at your top options bar and there are a couple of icons up here at the top. You want the middle one right here which is for sampling one. So that means when you click the mouse down, it is going to remember that color and the tolerance settings for as long as you hold the mouse down and drag.
The second parameter that you want to choose is Under Limits and you have choices of discontiguous, contiguous and find edges. When we are doing hair we want discontiguous because we want that diameter to be able to go in and delete a green area even if it is not connected to an adjacent pixel. And the tolerance setting, the meaning of tolerance is the same as I have explained before.
And we are going to start out, we are going to try a 64 tolerance and see what happens. And one of the best shortcut Commands that you need to know is the undo Command which is Control C and Command C on a Macintosh. Because a lot of times, you are just testing here first, to see which tolerance is actually going to give you the best result.
Now I have increased the diameter of the background eraser tool just like you do with the brush tool, you can use your right bracket key and your left bracket key to make it smaller. This brush looks a little differently. It has a crosshair in the center of it. And the crosshair, is the point that is being sampled. For example you do not want to click this in the hair or it is going to erase the hair. We are going for the green. And once you click, just keep it held down, and you can see, that it is erasing way too much. So you release and then do a Ctrl+Z on a PC, Command C on a Macintosh. So are now at tolerance of 64, is selecting too much.
So we are going to come back down to 32, and we are going to try that. So click in a green area, where part of your brush is overlapping in the hair here and this is working much better. Keep your brush button held down, and just draw a halo around the hair, like this. And then go back and forth.
Now when you release and click again, click again, click in a green area, it is sampling a new point but it is only one sample per click. So I am going to make the brush a little bit smaller here and zoom in using my Spacebar and Control key held down and click, just to come in right around here. And I want to sample that green area in the next to the earring here. So I will actually make the brush a little bit bigger. I will click once, keep the mouse press down, and I am just painting. And it is not erasing the skin because that was not sampled. Now I will release and come over to this side, click in the green area and then move the brush and we are here and clean this up. Okay, I am going to move this around.
Now I am going to add a slip layer underneath because as I said before, and just like in the other sample, sometimes the transparency grid can be deceiving. So, I will click on the background layer, I am not going to turn this visibility back on for it. But I am going to add a solid color fill layer right above it. And as I click, let me see; let me get som
