" Again welcome to pixel perfect beeper on -- actually all kinds of Photoshop stuff and whatever else comes up the one -- my sponsors godaddy.com. Where you get 96 dollars in free extras with your domain name. Godaddy.com. Deals. Include free hosting with your web site builder. A free blog. Complete email and so much more. Plus -- to -- pixel when you're seeing right here. When you check out with your dot com domain name get it but just six dollars and 95 cents a year. Some restrictions apply you've got to go to this site and find goes out. But until there check out code icon. So now. Got a bunch of requests. And I know about compositing things getting those edges to look right and so one. So I want to go in here and show you a composite. Now one thing that makes things -- of the fact that. When you select something and bring them to another image it automatically for until later ones -- and that there is a lot of things you can do to it. Now one of the things that you can do of course is to create what's called -- layer mask which allow you to. -- certain parts of that image to make it look good -- right here I got this image of good old David Prager. That's my producer until he's gonna separate layer I'm bringing into that image back which is right not -- wait -- that mayor and dragons here. And bring it in. And that area there now I just want justice face to appear I want everything else the kind of planned out. So what I do is just get that layer a layer mask I can do it from right here by clicking on this little -- I'll come up here. I'm the layers and say layer mask which gives me two choices -- I did a whole episode on layer masks. Showed do you hear reveal all give me a white one which would expose at all hide oh gimme a black one which -- Hide everything I say reveal all and there's my -- appears that it how right now it's like. As I said reveal all now and there I cannot create a tone and get my blend tool. Meg going to here and I'm going to use the radial gradient. Which right now I have my foreground colors at the white my backgrounds that the black through a creative integrated. The circle in the center will be the white so right click on movie -- bridge of his nose here and I drag out like this. Hate to see what happens. Yet at this nice little -- around him. Because you see right here in the layer mask I have this white halo. With a black on the outer edges. Now this has a lot more control than going in there and creating this election at a time which can also be done. Because I do have the ability to go in here and make a selection this -- select them right here like that. And that you're going there and say. Select refine the edge in finding beds allowed me to go in there and play around that they are going there and add a feather. And -- seen that effect it. But the problem this is it that this is going to make that selection that way. By doing it here. With a layer mask. I have more control. I can always change my mind in going there and say I don't want to see every appeared to be fuzzy. So I'm going there in my paintbrush as got a nice big rush they about it 200 that looks good. Switches to black and start painting. That area there action white. And ways and expose it accept the pain that area and writer on its face seem to have more control this way. I'm not erasing anything and simply hiding it based on the contents of that layer mask. So it allows me to go in there and -- individual images onto other images and play around with how they look. Now there are times when something. -- been selected you've gone to a lot of trouble to go and I select something maybe use an alpha channels technique or use the pen -- whatever. That's a case like this. Yeah we're gonna deal with the edge he knows at that coffee cup right now is against a black background. And I'm putting it into this image back here which has a white background."

" So we have what's called anti alias and that's that little edge over there and a zoom in on the corporate campus -- about SpinRite and hats and alleges. You see that there's a variety of colors in there a mixture between the flight phase of the cup and that black. That little mix of colors in the air softens that it its quality placing it creates an illusion that something as sharp. -- basically putting in focus without that you're gonna get stair step. So. And avoid that stair stepping. I'm gonna go in and select this spot among the evidence election. Now people say well if you want a soft -- that as selection in this case it's gonna make it black edgy even stronger. Because this cup is against black. About whether something is gonna spread out that led to selection which is gonna bring in some and a black giving the -- it black halo. So I want to avoid that. So if you don't have a path right here for the cup and turn that path into a selection. Here mate selection make sure there is no better. Click okay there's a selection but I can take this guy and drag -- here now comes in there it looks pretty good but if we're getting close. See that black kids is a dirty yet that's the ante is being that it's picking up from the retirement. As a control built into Photoshop. Idea under layer where data bound by only gotten that they adding has removed black -- Andy friends. The fringes going to go in there and look at that it. I notice of default is one you -- want to go to much more than one. Because what happens is gonna go into the image find a color as long outage as far as redundant push them out towards the outside. Now I used the fault of one and click okay. There we see it pretty much got rid of a lot of but it still left the little dirt smudges in there. Me and do that. Batteries you don't want to go further like. -- his shirt fielded different -- going on there if you give it a shot of me and fielding a television viewers have nothing different of ten. Post and you blue streaks on the from the different colors look wrong. You gonna keep at different down to the minimum now what I need to do is to fix this is to actually fix my original selection. And a dual what's called. Choke my mask spreading and so. There are two filters that was specifically designed for that. Now -- go in here and I've got my cup select. What I'm going to do to this is gonna save it as in alpha channel. Because of getting close -- in -- post here and it's. He selected. In real close."

" And turn on that path to path to see -- it's -- that edge. Now I could go in there and modify my patents a lot of time a lot of effort has that happened there. Lot of extra work alone make this really fast kept so I'm doing I'm simply gonna choke the mask. Back to a percent here turn them into a selection again. That and save the selection. To what's called an alpha -- Go into my channels and there it is. Anatomy. Now imagine a second go they are filters specifically designed for spreading into except that kind of brute force that these two guys right here. On the other we have yet and other we have maximum and no. A maximum. -- in default is one but Sierra spread it out. Further I go. Why did add math becomes but even the default of one is a little too much let's cancel that. Let's go to minimum. Then on -- smaller but again. It was a kind of brute force going one hi -- go the more chokes it to the point where it looked like the company more let's cancel that. I'm gonna do this interactive. I'm gonna go there and -- this mask. In a controlled way. It's getting closer again. And the -- that anti alias there isn't anti everything caused by this election that I may. And he we have to tones and there -- that mix the white and black give me a -- it. On the increase the range of values there by giving this a -- not does burn up marked -- blur which is going to double the amount you know I have four tones and there. -- additional dynamic range of grays and iTunes and it is is gonna give me the control that I want. Felt that do this I'm gonna go to levels. Image adjustment levels. Now. He's -- it is there this -- mostly black and white with a great between the legitimate right. The majority of the tones are here in the blacks and the whites they'll conflict there which represent those will grays in between. By pushing my black slider and you -- it appear interactivity that move -- you see that I'm choking the -- how it's getting smaller. Getting tighter. And I move the whites lighter and it's spreading. Well and we see. The image on top -- I've gotten image. The red represents the -- that's the hidden area so it's working at a quick masked by going to my levels again. And I took my mask. And -- And so that I see what's happening it's going in there eliminating. That those values and there I click okay. I can now going there and turned that election on. Make that selection I'm gonna hold down my command key in Tola PC and just click on the channel right here and Pallet and delicacy the selections in this election is inside. The actual tons of the cup. So. When I drag this and again. As it did before now we see that the ads is clean all the way around so we have two cups. The one has to dirty that's right through there and no one has. It is -- in there and took my maps compressed it. Very similar to going in here and things select modify and expand and contract. Doesn't do the same thing unit pixel screen into pixels except there it's just doing it based on values that -- set by doing it. The -- county have full visual control over how much you're spending which token that mask. -- that gives you a little more control of how that image is gonna come into the other and it's like going in there and eliminating all of that in the racing along the edges which you'll find when -- bringing in something from. It colored background it's very contrasting to the new image that you bring him into. -- something from that. And remember to play this way to learn. He got something that you want to be it it's to show you something in that sure how to get there are some decent magazine can't figure it out. The TV whenever sent me an email to -- and Revision 3 com and try to answer for. Next week."
