" And welcome to pixel perfect beeper owners who actually vote and Photoshop stuff. Want to thank my -- sponsors godaddy.com. They have some cool specials for you read if you entity code. Pixel -- on screen here. When you check out and I get your dot com domain name a question only 695. A year that's incredible deal. They -- post -- of your domain name Delhi design to -- for you so go check about it godaddy.com. Now. His aggressions time I have a lot of people west be about shadows. They weren't sure about how shadows work. Now which has a little complicated. So I want to get into. I'm just looking at them. Names here of people without and our talk about shadows and how they work now. A simple drop shadow that's no promises to shadow being -- something that's of war and so. Shadowed that's the more complex like going across the ground and up Walt that's been discussed. Try to discuss right now. Now on the screen here I've got one of -- things got Damon which did three shows on a long time ago. But I want it talk about this once just to give you the idea of how these shows -- going to work now -- it's -- this is an existing shot which and its. It's just the payments make believe the photograph I want to put something right here on this count on this out platform. So let's just say I'm gonna go in here and that layer I'm going here and create -- that allowed missile shaped like this. And we'll add a little. --"
" And her -- to the bottom of it right down here like that. I do think that and I'm gonna fill that with a nice little. Gradient -- go from this dark gray here to it is lighter gray. That and with. Gradient that's the near and go in here and create this -- shape like that now on the top given little circuit this election on top. To -- that and I'm gonna fill that with that. Like Colin says -- shape now it's casting the show. -- have to cat's shadow and everything else is casting a shadow. I'm not sure. Where that light coming from so I'm gonna do is I don't little lion the site experimentation here in another -- accurately a little guy from myself. Yeah cause that can really see like this red. And with my. The -- is right here. And make sure it's set to pixels on -- start right here at the shadow -- at the edges shadow and draw a line goes up to the top edge right here. -- the object is casting a shadow. Right there. -- that. Okay."
" And it's very thin lines that they want when we make in a twenty point nine pretty pixels. Strategy against -- don't really see this. Let's go there and ago right this it's and there's my line of sight. All right so I'm gonna do not take that. And move that over here. Ready to do this chick berry see that's. Where the shadows going to end right there street across. I can see from I think also that. -- the pretty much streamed across onto another duplicate. My little disk there. My little cylinder and no one and back on galactic transparency. And fill it with black. For now I'd go in there and distort that I take that shape in the go to rotate on first. Like so."
" Move into position right here where I want it. Okay and did my little guide si -- he got so not going there and do a little distort things and pulled aside over. -- That. And -- to this. -- though."
" Nick okay make it happen. We can get rid of this little piece on the side here that is gonna raced through child recruited -- unlock the transparency. And go and history that peace there being -- passing bit. And turn off that guide layer and there we see there were casting a shadow that followed the line of sight of everything else now because this is around it. This could be little more rounded up there as his question and then -- itself. I create an accidental belt looked airport is kind of modifying the existing one. And other -- and more complex of the show. -- And I've got this scene right here. This is gonna be a little more complex that this tree here and it's gonna be casting a shadow straight back and up the wall. -- gets complicated quite -- examples of stuff that they've done and is one thing that they've overlooked is how shadow actually tiles. -- sure study reality. Line something up against the floor there and hit with a spotlight -- nice strong night and watch how this data travels over objects and a wall that's what we need to do here. Going to create the illusion by. Creating shadows. And the duplicate. The mayor of the tree RBI for the one on top one and back a little lock the transparency. And the that would black as they did before. And I'm gonna -- transparencies it means we can manipulate this -- duplicated again. Duplicate that shadow lair -- who. Right so. Take the -- selected elements Q that's given it's Q. Here and they use that shadow. The handle and that's -- me over like this. -- we've all seen over -- even more area we have long shadow like that there is now. And the shadow it's further away from the object it starts to get a little Mary. So the happier I happened have an alpha channel that's going to expose the part of the image that I need to our radio we here so. And then go ahead and load that up to -- and shouted out countless working an earlier episode I explained how which how's it going there and see. And knows that and that layer of shadowed one at skewed and go in there."
" And applied a filter of -- ambler and which is -- out a little bit let's -- of two point one that's gonna click okay. I can -- select that. Bring down the capacity to say 8% and I got this myself. I'm not going to give it a mask. Give -- there a layer mask reveal all. And I will create a little tiny gradient than you gradient rating here -- period liberated. This thing. Made that part disappear it's going to make them straighter. Tell you what we'll hold the shift key that could strain that there are nice and straight. And you bring any capacity for that just a little more than that about 66 that's good. Now it's gotta go all the -- she's cute isn't going across the ground and I'm going up the wall that's -- the second one comes it. So I grab that second shadow bringing into position now it's further away so first and do is make it smaller than gonna scale it down. Much smaller go much further away to pick okay put it into position right about there were I want it. And give that that same gauzy blur that we gave you. -- just -- and are there it -- bring down the capacity to the same as the other colleges about 65. There it is and give this one. A layer mask as well. They reveal all. Give them little tiny gradient in here. -- like that and there we see there we had the illusion of the shadow travelling across the ground and then up the wall. Keeping in mind that as it got further away it got smaller. And as you got further away got an area. Right behind a tree trunk -- you see this sharp and it's getting softer is it's further away and the and the one going up the wall it's completely soft and much smaller. Again it's stunning reality it's gonna teach these things work. Like things look at how like to work how reflections are working the highlights are working these things that make things look real. How light hits things in next week's episode white is gonna pay a very crucial role in getting what a substance is made up. Best way to go in here and learn this stuff is observation and playing with the program. Think of it is working think of this plane. Have a good time in Osce and the next show."
