Join Bert Monroy for an in-depth discussion in this video Selecting the boat, part of Bert Monroy: Dreamscapes Volume 3.
On this screen we see a boat. It's an old boat that was grounded a long time ago. It's not seaworthy anymore, it's just sitting there rusting away. Well this boat is going to be the subject of our underwater scene. It's going to be a sunken boat way down below. So now were going to go in there and select this boat and pull it out of its existing scene. So here I'm going to choose, two ways of selecting, one which is the easy one and then one which is going to be a little more work. First one you're going to choose, color range.
Color range, right now, it comes in and finds a certain range right there, which is just blue. And so now I'm going to hold down my Shift key and I'm going to click and drag The cursor through the entire sets of blues and you can see that it's picked up all those other tones in there. I'm going to come down and pick up those lighter tones down there. So I picked up the entire area of blue. I'm going to click OK. You see that it selected the entire area of the blue. What I'm going to do is add to that selection. I'm going to hold on my Shift key and just kind of bring in some of this stuff that we see right here, right off the bat so we have it.
Now what I'm going to do is I'm going to save that selection. going to come in here and say Save the selection. And I'm going to call it boat. And I could deselect it now. And saving selection what its done is it's created an alpha channel which we see right here. Now that alpha channel has taken into account some of the major parts of the boat. And you can see that the hard things that would be to go in there. And set up by going in there and tracing all these little banisters and stuff, but now we get the rest of the boat to deal with.
So what I'm going to do is work from within the same area here. Now the parts that you see gray here, they were very similar in blue. Which is why they got selected as well. What I'm going to do is I'm simply going to paint those black. You've seen me use alpha channels in some of the other classes and then I explained alpha channels. So here what's happening is I'm just going to go in there and black is going to protect, so I hide those. So I turn on to see the RGB and now that I can see it, I'm going to start to continue to paint it. And then if I paint with black, I'm going to go in there and make it black.
And in fact, what we could do is go in there and invert this, because what we really want to do is select the boat. So I'm going to go in there, and invert the alpha channel, and now we see it as white. See there it is. So now I can go in there and retouch just a little bit. Like for instance some of these greys we can get rid of those really quickly by going into something like levels. And levels I can go in there, and just say let's make those dark tones darker. There you go see so those greys disappeared because I brought my dark slider over into the darkening range which made those little areas much lighter.
See the same thing here. There's some little strips of water back there. By pushing the black slider in, those were eliminated right of the bat. And now I need to do the rest. So I want to see those color layers on top. So I start to paint, and I'm getting real close. And basically what I'm doing is kind of like doing in a coloring book. We're going to go in here and start to paint. I'm going to go right through this, along the edge of the boat, just like so. I can start to go in there and just expose just the parts that I want of the boat itself and go all the way through. Now a lot of the bottom of the boat is like it is right being covered by land it is going to be covered by our underwater-scape, so it not that crucial that I get all of it.
But I do want to get the major parts of the boat that are visible. So I'm going to go in here and select that boat. And I'm painting with black which means that all of this area here. Will be hidden. So now, to save some time, you get the general idea of how to get this done. The end result is going to look like that. Where I have my boat completely isolated making it easy to go in there and select the boat and pull it out of its background so that I can then utilize it on the water scene. And the next movie we will start to do is to create the underwater scene itself. And you see up here? See these grays? When you stand back and you look at your image, you definitely want to make sure that everything, that you don't want to be selected is in fact black. So, I fill that area with black and there we see that outboat is now completely Expose.
And evenUNKNOWN you need to go in there and just get rid of some of that stuff. But you get the general idea of how you get the boat selected away from its background.
