Polar Coordinates

Now let's look at a weird way of bending things. This method is going to create tiny little planets, uh, or tiny little doughnuts. And I'll show you a few examples. If you've ever seen images that looked like this, this that's more the doughnut variety. Those were all created with a filter that is known as polar coordinates. And so I want to show you what you need to do if you want to create one of those little planets. So here, we're going to do it with some lions in order to create something that looks like a planet. We're going to be using the filter called filter distort polar coordinates. And it has two features to us settings when you get into it. Rectangular two, polar in polar to rectangular. I'm gonna use the top option because we're starting out with a rectangular document and it's going to wrap it around now in order to really understand what it's doing. So it's kind of wild what we got here. If you look at it, we now have those lions on the outer edge of this, and we have t...

he trees going in towards the middle, which is pretty crazy, but in order understand it. Let's grab a simple image. Here's my simple image and just noticed that that says top and bottom. And if I choose filter distort polar coordinates and I use that top setting, let's figure out where the top ends up and where the bottom ended up. So you noticed that the top edge of the photograph ended up being the center in the bottom edge of the photograph ended up being the outer edge. And so if we want something to look like a planet, whatever should be out in the atmosphere beyond the planet should be at the bottom of the photograph and whatever should make up. The planet itself should be at the top of the photograph because if you look here, that becomes the center and this needs to be a square in order. Get around planet. If you apply it on a rectangular, eventually get an oval. So if you look at this, didn't I say that I wanted what ever should make up the planet to be at the top of the photograph? So let's go up here and choose image, image, rotation, flip vertical. So now whatever is at the top will become the middle of the planet. Whatever is at the bottom will become the outer edge where it's like the atmosphere around the planet. But if I apply it to this, I can try it real quick. Since it's a rectangular document, we're gonna end up with an oval and I'd rather have it be round. So choose, undo. We just need this document to be around. So I'm gonna go to the image menu and choose image size and usually when you change the width and here the height changes along with it to maintain the aspect ratio original ratio. Well, if you turn off this little link symbol, then it doesn't change in both. So I'm just gonna copy whatever the higher number is. I'm going to paste it with lower number Waas to make this a square. It is going to do that by stretching the image. So if I click OK, now it's stretched. And if I zoom out it's a square document. Then I'm going to apply that filter called polar coordinates. Click OK, and now we have a planet. The only issue with the planet will not the only issue. But the main issue with the planet is there is a seam. Can you see the seam right here? That's where the left edge of the document is touching the right edge of the document. If you want to avoid that scene, choose undo in when you're in. This were about Teoh to apply the filter instead, apply different filter. The filter is called filter other offset Offset is like a conveyor belt. It just means move my picture. Let's say to the right, in whatever part of it goes beyond the edge of the screen haven't wrap around like a conveyor belt. Would is if that was one continuous piece. So when I choose Offset, I just bring up this horizontal setting and it just moves the image to the right. And I'm just exposing the seam right here is the scene. And so at this point, I could come in here and retouch out the seam. I'm not going to spend much time doing that, but I could hear you something like the, um, spot healing brush that's not quite appropriate, but might have to do the top part manually. That looks all right. But now I don't really see a seam in it. And now I could go back and apply the filter. Polar coordinates look OK. And now we have a planet with No, uh, seem. The final thing you might want to do is make around selection in fill the outer area with a solid color, because otherwise, whatever it was right on the edge of the picture right here just gets extended out to the edge of your photograph. And you can fill that in with whatever color you want. Just make a solid ah, round selection. Select inverse to get the opposite see of the corners in fill with whatever you desire. So if you want to see other examples of that same thing, um, let's see this original just flipped and then stretched turns into either this if we put the content at the top of the photograph or if we left it at the bottom of the photograph. You get this instead. But you gotta retouch up the seam. This came from this image here, and this image here produced that. So now you've gotten a pretty good idea of how to warp bend in liquefy images and photo shop and just try to combine these ideas with what we covered in other parts of the ultimate guide. Because I find oftentimes I use a lot of these features when I need to perform complex retouching. Area I copy from in one part of the document doesn't quite fit another and using what was in what's called the Clones source panel to rotate in scale and even flip. Sometimes that isn't enough. And that's when I turned to some of these features in order to really be able to melt my image. And if you watch the advanced retouching lesson, you'll see how I did that using puppet warping. But this is just another installment in Photoshopped. The Complete Guide.
