Hello, welcome to Knowledge City's Intermediate Course on Adobe Photoshop. My name is Jeff Drylovitz, and today I'll be walking you through the Image Size dialog box and the importance of resolution. When considering screen resolution, it is important to remember that this represents the number of pixels a monitor can display. So if your screen resolution is 640x480, then your screen is displaying 640 pixels for the width and 480 pixels for the height. To access the image size options, you can either go up to Image in the drop-down menu and choose Image Size, or hit Command Option I for the keyboard shortcut. So once our dialog box is open, you'll see that we can move the image around within this space right here. We can also zoom in and out as needed, so we can get a clearer idea of what we are doing to our image as we are resizing it. So starting from top to bottom, we have got our image size, so the actual size of our document right here. We've got the dimensions, just as I was speaking before, about the width and the height. That's how large it is in pixels right now, 330x220. And I can also change that to percentage, even at pixels, inches, whatever option suits your needs. I'll stick to pixels for right now. Next down, we have got our Fit To option, our Fit Toon drop-down menu. So you can see this is showing it at its original size. Now what I can do is I can choose a preset if I'd like. So I've got various presets in here that can adjust the width and the height or the resolution, or both together, all depending on what I'm looking for. So you can see some at 144 PPI, pixels per inch, some at 72, you've also got the same at 300, or you've got different sizes, you know, photo sizes down here, 4x6, 5x7, and so on. You can also load presets as you've had, save presets based on what you've inputted already, or create a custom one. Now when it comes to actually resizing our document, we can do this manually as well. So we've got our width, we've got our height, we've got our resolution. Now here's the thing to keep mindful of. If you adjust the resolution before you adjust the width and the height, it'll change it proportionally. So now what you want to look at here is you can adjust your width, your height, and your resolution. So I can change the width, let's say I just want to make this 15, and you'll notice that the height changes in proportion with that. Now if I want to take this out of proportion, I can unlink right here. There's a little chain link right here, it's a constrained aspect ratio. So right now, they are linked up. If I unlink them and I want to change my width to say 20, well you can see in my image here if I hit OK, it's now stretched out in a, you know, very unrealistic sort of way. Let me undo that, or remember Command Z can be undo, I'm going to bring open my image size dialog box again using Command Option I. So as we are looking through here, we can also change the units of measurement for our width and our height. We've got inches to work with, again, the same options that we had up top for our dimensions, pixels, percent pixels, inches, centimeters, millimeters, points, picas, and columns. I'm sticking with inches, that's just the unit of measurement that I feel works best for me personally, but you use what works best for you. So I'm going to link these back up here. So now what we have also is resolution. So resolution is important depending on what you are working on and what size you need to work in. So if I want to create something that's going to be printed out as say a banner or a poster, I'm going to want to hire resolution because again, this is 300 pixels per square inch of my document. Now, if I were to drop that number, say, to 72, you can see the image gets smaller, and as I zoom in, it becomes more pixelated. If I were to say move that up to 120, there's still pixelation going on in there, not as much because there are more pixels per inch in there, and if we bring it back to 300, you can see you can zoom in a lot further before it becomes pixelated. Now smaller resolutions, that's better for something you're looking at on a smaller scale. So if you're looking at saying avatar for social media or a web banner of some sort in a situation where you don't need to zoom in as close because it's just in a fixed place on a device. So that's a situation where you'd use a smaller resolution. So let me just change my width and the height so we can take a look at what we have here. So let's just say I want to change my document to 120 on the resolution and make my width 5 by 3. Again, we're keeping constrained, I hit OK. My document is now smaller. I can zoom in on it. We can see the difference here, and if you look at the rulers up top, you can see it is 5 inches by 3 inches. That is all for our look at the image size dialog box. Stay tuned for the next lesson where we look at resampling within the image size dialog box. Hope you learned a lot, and thank you for watching.
