Knowing how to effectively zoom in and out on our photographs is essential. Whether we need to zoom in, in order to evaluate or make corrections to our pictures, or just if we need to change our zoom right in order to get a sense of our overall image, we need to know how to work with the Zoom tool and also how to dial in some important zoom preferences. So let's start off by taking a look at the Zoom tool. You can select this tool by pressing the Z key or just by clicking on the Magnifying Glass icon, which you'll find in the Tools panel. Next, once you select that tool, you notice that you have some preferences up top.
One of the preferences is resize the windows to fit the zoom rate. This is really helpful if you have a window which is floating. Let me show you what I mean. If you navigate to the Window pull- down menu. Here, what I can do is turn off the Application Frame. Well, now this window is just floating here, and with the Zoom tool if I click on the image, you can see it also changes the size of this window. If I turn this option off, well, the window stays the same size, but when I click the image inside of the window is the only thing that changes.
So you just want to choose the option which fits your workflow. Let's go back and turn that Application Frame back on, because typically we'll have that on and here we can then see our photograph. Well, in this case, I've zoomed in too far. I need to zoom out. Well, the easiest way to zoom out is to hold down the Option key on a Mac, Alt key on Windows, and that will change the cursor. You'll notice the little magnifying glass now has a Minus sign icon inside of it. So now if I click, I can then zoom out. And here I am clicking multiple times so that my image is much smaller.
Another way that we can zoom is with what's called Scrubby Zoom. With this option turned on, well, you can just simply click and drag. And as I do that--either dragging to the left or to the right--you can see that I can change my overall zoom rate. Now let's say that we've zoomed in and we just want to see the whole image. How can we do that quickly? Well, we can do that by double-clicking on the Hand tool. When you double-click on the Hand tool, it takes your zoom to a view so that you can see the entire photograph. All right. Well, now that we know a little bit about zooming, let's take a look at a few preferences that we might want to choose inside of our Preferences dialog.
So navigate to your Preferences dialog, and let's go to the General tab. Well, here you can see we have three different options for zoom. We already talked about Zoom Resizes Windows. Then we have Zoom with Scroll Wheel and also Zoom Clicked Point to Center. By default, these two options are turned off. I recommend you turn them on. Let me show you why. Let's go ahead and click OK in order to apply those. Well, the first one is zooming with our Scroll Wheel. If we have the Zoom tool and if we have a three-button mouse, we can then simply use that Scroll Wheel in order to quickly zoom in and out.
The other thing that's helpful is to have that preference for changing the centered area of what we're zooming to. In other words, let's say that with this picture I want to zoom in on the hand. Well, if I click here, what it will do is it will allow me to zoom in on the image. But you also notice that it re-centered my photograph. I didn't move the Zoom tool, but it moved the entire image so that this now is in the center of the frame. This is especially helpful if you want to work on an area of your image, like the eyes. You can click there and it takes it to the center of the screen so that you can then focus in on that area.
Otherwise, what would happen is you would zoom in and this would be right on the edge and you couldn't really work with that part of your image. So again, I recommend you turn that preference on because I think it will really help you out. All right. Well, there is just one more thing that I want to share with you here before we wrap up this movie. Let's go ahead and double-click the Hand tool. Well, if we double-click the Hand tool, we know that our image now fits inside of this view. Another thing that we can do is double-click the Zoom tool. Well, why would we want to do that? Well, if you double-click your Zoom tool, it will take your image by default to 100%.
This is helpful to see your image in a 1 to 1 view. You can see the actual pixels. In other words, here I am not zoomed in or out, this is just an actual representation of my image. So again, those two double-click shortcuts, they work well together. Double-click the Zoom tool to go to 100%. double-click the Hand tool and that will take you to a fit in view perspective so that you can see the entirety of your photograph.
