 So we've got a photo of a dog we can use to talk about the difference between canvas and an image. So if you think about the image, how it looks versus the canvas as the actual width and height of the image itself, think about a canvas like your painting. You can choose your colors for painting. You can choose what it is you're actually going to paint. Think about Bob Ross painting happy little trees. That's all what goes in the image itself. But the canvas, of course, is something you decide pretty early on. Are you doing an 8x10? Are you doing a 5x5? That's the difference here. And Photoshop treats it a lot of the same way. So with canvas and image, both options are available up under the Image menu. You just click Image. In sort of the middle of that menu we have both Image Size and Canvas Size. So I'll show you both of those and I'll start with just Image Size. So by clicking that you get a little preview of the image itself here. On the left we can zoom in and out of that as we need. So you can really see exactly what changes you're making to your image as you make them. Of course it's great to know what you want to end up with when you're making these changes. You don't always know that. So in all cases it's best to err on the side of caution if you don't quite know how big the finished product needs to be while you're working on it. By all means do this at the end. But if you do know if you want to begin there that's okay too. So we can choose from these options here on the right side it defaults to the number of pixels. But you can always change that if you know the inches that it's going to be. If it's going to be something in print for example or if you're not in the US centimeters, millimeters, you have a lot of options here. You can also do it as a form of percent. So of course the default 4% is 100 because that's the size that you're starting with. And then you can always change that to something smaller. And you can see once I punch in 50% the preview shrinks down by half. So if I choose okay on that I've chosen 50% of the original size. You'll see the image itself shrinks down. So the image goes to 50% of what I specified. If I'd chosen pixel or centimeter or inch or anything else same result. So that's the difference between or that's image size. Canva size though. I've chosen image size to be a very specific set of pixels or a percentage. Going back into the image menu I chose canvas size which is right underneath image size. If I specify a different size here let's say I choose, I'm staying on pixels if I choose 1500 width and a 1000 height that will bring the edges of the image down into the image itself. It will basically crop anything that exists outside that specific measurement 1500 width by 1000 height. And I'll click okay and you can see on the image itself what happens to the image when I choose a smaller canvas size. And it wants me that I'm shrinking down basically. The image itself won't resize to a particular percentage but it will crop everything beyond the size that I specified. So you can see it's kind of a tighter zoom on the subject itself once that. As you can see from what the original was versus what it is now as opposed to image size where you've shrunk the entire image, canvas size will either crop to or expand beyond the size that you specified. Let me back up a moment and I'll show you the opposite. So I'm going back to the original size and I'll go back to image, canvas size and I'll specify a larger canvas this time. I'll say 3000 by 2000. And you can see the arrows beneath it are now going outwards rather than inwards. The last time they were pointing to the center, this time they're pointing outwards. This tells me that there's going to be more canvas space around the actual subject of the photograph. So if I click okay once that shows up for you folks you'll see there's basically the equivalent of a mat. Like if you're framing a photo on your wall you've got space for a mat. This is something that I had to do. I framed a wedding photo that we wanted to hang in our house. We needed room for the mat so I created a canvas size that was larger than the photo itself so that when we printed it out at the printer there was space for that mat that wouldn't just cut into the photo itself. So this is an important consideration when you're adding things to your canvas. You have a logo or you have a photograph or something. You want to create extra space around something. You can always expand the canvas size without having to sacrifice any quality or having to crop or anything like that.
