Hi there, this video, we're going to look at lights in three D. There are four kinds of lights will work out how they affect our objects and how their car shadows will show you how to move them around to get kind of more dramatic effects. That's not very dramatic, but you know what I mean? Let's jump in now and work out how they work in Photoshop. Alright. Working with lights now by default, you're given a light here and our environment, it's just a default light just to give things shadows and so they can be seen. So you've got one light to start with. What we're going to do is look at adding our own kind of like purposeful lights. You do it by on your three D. Lay here down here there's a little light bulb, let's look at an infinite light. Think of the infinite light as the sun, you can't really move it physically, you can change the angle by grabbing this like little ball thing on the end here and you can kind of decide where it's going to be cast and you can see the shadows affecti...

ng it in the background there. So I'm gonna go straight up and try and cut, you can see the shadow being cast on the background a little hard to see. I'm gonna have rendered to give you a quick view Okay, and you can see here it's kind of like from the top, it's kind of casting shadows on itself here and onto the background. So infinite light is a perfect one. Think of it as like sunlight just kind of a good fill light and that may be all you need. What you might find though is I'm gonna hit escape stop rendering is that you've got you've now got two lights, you've got the environmental light which is kind of like an ambient light plus you've got the sun so they're both working together, let's say you don't want the environmental light because you just want this really strong sunlight. So here an environment just turn this one here, turn ibl off now we've only got this infinite son. It makes a I guess a little not clearer but it's just one directional sunlight now in Orinda it really looks like we've just got a single bulb, it's not super strong but in the shadows it's super dark whereas an ambient light bounces around and kind of fills lots of holes. Things you can do to adjust the infinite lights or whether it's selected down here, you can decide on how soft the shadows are or shadows whether it has shadows at all. You might not want them at all. So we've got shadows. The softness is really low but watch this if I crank it up it will get more feathered and more feathered rather than being a really kind of harsh, strong fixed shadow give you a quick render as well to show it okay, you can see now it is like a kind of a fluffy shadow. Alright, escape. You can also play around with the intensity. Okay, how bright this thing is and how maybe not bright It is easy one and color just means it's going to tint the color. So you want a kind of a weird yellow tint, not a weird yellow tint, you know what I mean? You just want to kind of a daylight kind of flavor to it or you go something a bit more indoor, see more like fluorescent lighting, kind of some sort of blue. Alright, let's look at some of the other lighting types. You've got two other ones spot and point to a very similar thing if it likes like the sun point light, let's turn that one on. I'm gonna turn off the Infinite son. Think of a point light is carrying around a bulb physically carrying it around and moving around the room. Whereas the infinite light just comes from everywhere in one direction. The bulb is actually something you can find. So with that selected, we can actually move it around now for me, I can see it. It's down here, You might have to zoom out zoom zoom zoom zoom and you should be able to see it. And what we can do now is it's a little hard to move this thing around. What you might do is look at from the top. Maybe we can go up to our views. Current view and go to top. This might be the easier way to look at it. So I've got my point light selected and I want to move it. Here's the move the red one. This closer, you can see, I'm actually right in front of the text now. So now if we go back to my current view and actually go down to actually there's an easier way you can click on, read option to their can you see I've moved this bulb really close to the artwork, so it's kind of like carrying a little lamp around, okay, And it's going out all directions. It's pretty cool, kind of moody, spooky Z. Moves it away and close and you've got your X and Y to kind of move it up and down, zoom a little bit to zoom out. Go to your top view and see if you can make it happen. So that's a point light. A spotlight is kind of similar except it's directional, does the same sort of thing. It's like you physically carrying a spotlight around and escape. That's pretty cool. I'm gonna turn that one off, We have no lights and I'm going to add the last one which is a spotlight. This is even harder to use if you've never used three D I'm gonna zoom out, click on current view, I'm gonna click on this first option and I'm gonna see if I can find there he is there. If I click on my spotlight, you can see it kind of, it's casting this way, it's only just getting a bit of this and it can be fun to you. Let's again get it into a kind of a spot where we know what's happening with it. So we're gonna go to current view, let's go to top, see where it is, zoom out, there's my little light there, I'm gonna grab my move option, I'm gonna click on my spotlight, it's shining kind of through and past my object, which is cool. But what I wanna do is I want to try and move it, move it this way, I need to rotate it around. I'm gonna use the rotation option and I'm gonna move it, so it's facing there right closer or further away. So that's looking at it from the top, we know it's kind of at least from the top down, we can see it pointing at my object, go back to current view. And let's use the let's look at it from the right hand side. Okay, so it's kind of coming down and towards it and that's fine spotlight. I might bring it down this way closer in and say I want to rotate it, make sure you got the rotation and click and drag it, It's a little bit hard left and right, not up and down. So I've got a spotlight pointing at my text and my background. Let's have a little look, let's go back to my read option to click on my spotlight, you can see mine here. It's actually pointing kind of just up into the left, so I could play a fun game of trying to rotate it and clicking and dragging and rotating it around. I'm gonna use the rotate 3D object and try and drag it around to point it at my graphic. It's kind of working so it's very directional and we have to do a lot of switching between different views to try and work it out. All right, the other thing you can do is you've got the hotspot and the kind of light, so basically how focused this is okay, whoops, wrong option. Okay, it's these two little dots here so I can expand this out. Okay, so what's happening is inside the circle is full brightness from this light, you can adjust the intensity of that center chunk, then you've got the fall off, okay, Which is anywhere between this hot spot and the outside of the cone, so there's no light outside of this. Watch this if I tuck you in very narrow and then this in very narrow, you can see the light is only affecting within that little range there, so I'm gonna expand it out and again, this will depend on what you wanna do. Do you want to really narrow kind of searchlight, you can adjust the hotspot and cone over here. It's a little hard to work out on the graphic Brenda. You could see they had a kind of a weird square going on that was just temporarily while it was just working okay. And in my case I want the count to be a lot bigger. Want the shadows to have a bit more softness and I'm going to play around with the rotation of it so spotlight selected the orbit option and I'm just going to kind of wiggle it around until I get it. How I want Brenda. Alright, so that is a half render, but that is the difference between a spotlight, you point it around and it's super fun and not difficult. It's yeah, it's difficult, it's hard to get it pointing in the right direction. Point light is quite easy, you've got to make sure you zoom out and actually find it on the map. Okay, You might have to train around with the different views just to figure out where it is in the world and I can see mine there, there's my little point line, move it to where I want it to be up down left, right, I can adjust how bright it is, how fluffy the shadows are, where there has shadows at all. Or you can use the infinite light Okay, which is more like you just play around with the direction it's hitting things all cars from the same angle, my read option to amen it's just a nice simple light or you might turn that off and use just the environment light or it's just kind of a generic fill things. Refract and bounce around and fill things is a there's a bit of contrast. Okay. And their shadows cast, but it's a bit more like real life fish. Well, you can turn them all on, have them all battling for supremacy and all kind of over saturating each other for end of that, wow, that's bright. All lights working together as one. Alright, so that's gonna be it for lights. Let's get into the last video where we look at rendering for our final production.

Amazing experience but it is little old. You should update with latest version of PS

Great class, but outdated PS version. It was confusing sometimes. Some tools are not in PS anymore and more tools have been added which is not included in the course.
