In the last movie I suggested you used the pelican image to be able to add in the pelican into the lower edge of this page using the similar technique to what we did. Here's my solution to how I got this done. The image has had an Alpha Channel applied to it around the edge. I've stretched the image up a little bit and moved it directly into place. Now let's look at using the Image Adjustment tool. In our Media window, I've added an image called image_adjust. Go ahead and drag that onto the page. Close the Media Browser.
Make sure it's a Floating image, and we're going to adjust the size of the image so that it fills the top of the column on the right-hand side of this page. There we go. Now, the image is not a bad image, but the problem is it's not quite exposed properly. So let's go ahead and make a few adjustments, and we can do that right here inside of iBooks Author. With the image selected, we'll click on the Adjust Image window in our Toolbar. The Adjust Image window is very similar to the Adjust Image tools that you find in other Mac applications, such as iPhoto.
Let's go ahead and apply some adjustments to this image. The Brightness is already pretty good, but let's go ahead and boost the Contrast just a little bit and see what that looks like. I want to take mine up to about 13. That's looking a little bit better, a little more Contrast there. To help us in making the adjustments, let's go ahead and zoom in on the image a little bit more so we can really see it. Next, let's go ahead and boost the Saturation. The default setting is set to 50, which is halfway. I'll go ahead and boost this up some, and we can see that some of the greens and some of the other colors are really starting to pop out a little bit.
That's looking much better. Already the image is looking a little cool. Let's go ahead and warm it up by shifting the temperature up just a little bit, maybe only to about 5. That adds just a little bit more color here into some of these rocks. Likewise, let's go ahead and adjust the tint down just ever so slightly, maybe -1. That adds just a little bit more magenta into the image and pulls some of the intense green out. Next, we'll add just a little bit of Sharpness to the image. We'll bump this up, maybe about like that. That's looking a little bit better.
It's just making the detail show up just a little bit crisper. Finally, the image is overall a little bit overexposed, so let's reduce the Exposure down by dragging the slider here to the left-hand side just a little bit, maybe about -10. There, this image is now looking much better than it was when we initially started. The specific techniques that you would use for any other image will vary, depending on the image. It's going to take some playing around with to be able to get the image to look just the way that you want it.
I'll go ahead and close the Image Adjustment tool and deselect my image to see the final results. While the Image Adjustment tools here are not meant to replace a professional image editing tool such as Photoshop, they will get you pretty close on an image that's already almost there.
