Join Garrick Chow for an in-depth discussion in this video Cropping and straightening, part of iPhoto for iOS Essential Training.
Now I'd like to start looking more closely at the editing tools that appear here in the lower left hand corner of the iPad when you have a photo selected. If you're on an iPhone or an iPod touch, you'll see a little tool box icon in the lower left hand corner and tapping that will reveal these tools. My default, browse is selected. And that just indicates that we're in browsing mode where we can scroll through our thumbnails looking through our photos. The tool that appears right next to that is the Crop tool. And this is actually two tools in one. With the Crop tool selected, you can both crop your image and straighten it.
Let's take a look at how to crop first. With the Crop tool selected, if I hold down on my image, I see this grid appear. But moving my finger over the image doesn't do anything right now, because I'm seeing the entire image. Nothing has been cropped out yet. But if I place my finger over any corner. The grid will reappear and I can drag it to make it any size and aspect ration I want. So that's how easy it is to crop an image to any size you like. And now that I'm cropped in, when I tap and hold on the image, I can drag it around to reposition it within the cropped area. So, that's how to free form crop an image but there may be times when you want to make sure the image maintains a specific aspect ratio.
First, I'm going to tap the Options button, and choose Reset Crop and Straighten. And that reverts the photo back to its original state. And as you probably just saw in that menu as well, here's where you can select specific aspect ratios. Here you'll find two pages of aspect ratios for both portrait and landscape orientations. For example, if I was going to use this image in a video slideshow I was editing together, maybe an iMovie, I might choose the 16 to 9 ratio, so I can set here an iPhoto how the photo will be cropped. When you crop a photo, iPhoto automatically crops based on the center of the photo.
But as we just saw, I can now drag the photo around to reposition the visible area. Now, at this point, if I were to drag a corner of the grid to crop in some more. Notice, I'm once again able to drag into any proportion. Which may not be what I want to do in this case. Maybe I want to keep the 16 to 9 ratio, but I want to crop in a little tighter on my image. First, let's reset the image again. And I'll select 16 to 9 again. Now, one way to zoom in, is to simply pinch out. So, with a combination of pinching and dragging, I can reposition and crop the photo. Let's reset that again. But you may prefer to drag the grid, rather than pinching in and out.
To keep the grid in the correct proportions, first, select your aspect ratio. Then tap this Lock button. And as you can see, that locks the grid into the 16 by 9 proportions and I'm free to resize it as I like. So, that's how to crop. Now let's talk about straightening an image. Because if you're like me, you'll often notice that you weren't holding your device perfectly level while shooting your photos. And it's nice to be able to rotate them from right here in iPhoto to straighten them out. And there are actually several ways to accomplish this. Let's select a different photo to see how this works. I have a photo here of Coit Tower in San Francisco. And we can tell just by looking at it that it's a bit askew.
It kind of looks like it's leaning over to one side a bit. So, once again, I'll select the Crop tool. And one way to straighten this image is to simply place two fingers on the photo and rotate them in the direction you need. Now, as I did that, you probably saw this dial down here at the bottom of the screen. You can also move the dial itself to straighten the image. Which gives you the advantage of not blocking your view of the photo with your hand while you rotate it. Now, the reason the strain dial is found with the Crop tool is because when you strain a photo, you are, in fact, cropping it. iPhoto has to zoom in slightly on the image so there are no blank sections inside the viewable area of the photo.
If I hold down on the image, you'll see the cropped out portions of the image around the edges here. The same way we saw the cropped portions of the previous image we were working with. All right, so you can rotate an image either by using the style or by rotating with two fingers. Now, iPhoto has yet another way to rotate the photo that takes advantage of your device's built-in gyroscope. To see what I mean, tap the dial at the bottom of the screen once. Then simply rotate the iPad itself to adjust the straightness. And when you're done, tap anywhere outside the image or tap the dial itself again. Personally, I think that's the most difficult way to straighten an image, but it's also a fun way to show off with iPhoto.
Now, with some photos you'll find that iPhoto is able to automatically detect a horizon. In which case, it will show you a tool to automatically straighten your photo. For example, I have a photo here of Alcatraz island. It's fairly level, but if I select the Crop tool, iPhoto detects the horizon and places this line over it. If it looks like it's correctly identified the horizon, I just need to tap this Rotate button on the right side of the line. And it straightens the image for me just like that. If, for some reason, it still doesn't look straight to you, you can still manually adjust the straightness using any of the other methods we look at.
And again, you can always undo any edit by tapping the Option button here. And choosing to either remove the effect or edit you just applied, in this case Reset, Crop and Straighten. Or, if you tap Browse, you can tap Options to access the Revert button, which will remove all edits you've performed to the photo. But in this case, I'll leave things straightened out. So, that's how to crop and straighten images in iPhoto.
