Mountain Lion's Preview application serves not only is a way to view graphics and PDF files, but also as a light editor. We'll begin our look at Preview by examining how it works with image files. So to do this I'm going to go to my Documents folder, and I'll double click on an image, and automatically that image will open by default in Preview. Now the Tool bar includes the kind of tools that you want to use most commonly, and that includes zoom tools. So zoom in, zoom out.
If you want to share this, click on the Share button, you can email it, you can send it through a Message. You can AirDrop between computers, post it on Twitter, post it on Facebook, post it on Flickr, or you can add it to iPhoto. You can also rotate your images, and you can annotate them, and here's the annotation button, so click on that. Once you do that you have a variety of tools. First one is a rectangle. So if I wanted to call something out, I can draw a rectangle like that, and if I choose to, I can change the thickness of the line around it.
We're going to undo all this to get rid of the rectangle. I can also draw an oval. I can create a line. Let's make these lines a little bit bigger so can see. I could choose to create an arrow. Choose the arrow style.
I can add a text box. I can add a text bubble. Click outside and I can get rid of it by selecting it. I can make a little dream bubble if I like, and we'll get rid of that. And then I can choose the fonts that I use within these bubbles or within some kind of text box.
You can also choose a variety of selection styles. So I can select this area, and I might want to copy this, for example, and then I can choose New from Clipboard, and I have just that area that I highlighted. And no, I don't want to save it. You can do the same kind of things except now you have an oval or round selection tool.
Copy, New from Clipboard, and you can also choose a lasso style. So I wanted to just select this portion of the flower, I can do that then Copy that bit, New from Clipboard, and there's that clip. Now this is a pretty rough selection. Fortunately there are some tools built in that help you create a better selection. So with this Outliner Tool I can make a much broader selection.
Again I'm going to draw it very roughly here. And when the points meet and I'd let go, now I've got my selection. This is much closer than what I selected with Lasso Tool. Or you can create an alpha mask. So I'll click somewhere I'll just start highlighting this yellow color, and I'm doing this by dragging a little bit to the right. If I continue doing that, you notice that it selects more of the colors as it goes outside that yellow spectrum, but I'll drag back to the left, grab just the yellow.
Now that yellow is selected, so I'll copy that, New from Clipboard, and you see I have a much better outline, just using this simple tool. I'll get rid of that. I can also crop if I like, so I'll click this off, go back to the Rectangle Selection Tool, and now I can crop the image. I'll undo that. And if I like I can also change the color, very much like iPhoto. So bring in some Highlights, I can change the Exposure, bright, darker, change the Contrast.
Blow up the Highlights, blow up the Shadows, change Saturation, change the Color Temperature, Tint, make it old fashioned-looking, kind of like that, and I can change the Sharpness. To get rid of that just Reset All and you're back to your original image. There are some helpful things in the Tools menu as well. First, you can show the Magnifier, and this gives you a chance to look at the details of your images. We've already looked at Adjust Color, but you can also adjust the size of your image.
So as you can see this is quite a large image, but I can change it so, we'll make this instead, say, 10 inches wide, and click on OK. So if you need to quickly resize an image you can do that with Preview. And if you have a lot of different images open, you can view them as a Slideshow. I have just the one image here so I don't need to do that, but you can if you want, or you can choose to Enter Full Screen. Finally, you can also use Preview to change the image format, so choose File and then Export.
Currently, I have a JPEG, but I can use a different format. So I can change this to a PDF, a PNG, a TIFF file, or a couple of other different file formats. And we'll cancel out. Again, as with TextEdit, Apple packs a reasonable amount of power into a seemingly simple application. You can try these tricks with your image files as well, but we're not quite done with Preview yet. In another movie, I'll show what Preview can do with PDF files.
