Video: Cropping to a specific ratio or size

In this movie I'll show you how you can crop to a specific ratio, such as 4 by 5 or 5 by 7. That kind of thing. You can also dial in specific image size and resolution values if you like. I'm going to switch back to the crop tool and then I'll go ahead and redefine my boundary a little bit so that it's very wide, like so. I'll go ahead and drag out the left side a little bit and the right side quite a bit so that we have more of a sweeping panorama. And that will help me demonstrate what the ratios look like.

Cropping to a specific ratio or size

In this movie I'll show you how you can crop to a specific ratio, such as 4 by 5 or 5 by 7. That kind of thing. You can also dial in specific image size and resolution values if you like. I'm going to switch back to the crop tool and then I'll go ahead and redefine my boundary a little bit so that it's very wide, like so. I'll go ahead and drag out the left side a little bit and the right side quite a bit so that we have more of a sweeping panorama. And that will help me demonstrate what the ratios look like.

You can select a ratio from this pop-up menu right here. For example, I could switch to 5x7, and that's going to go ahead and constrain my crop boundary like so. If I don't want 5x7, I really want 7x5, I still want a horizontal shot, in other words, then I can click on this little double arrow icon. In order to swap those two boundaries and I'll come up with this crop here. Now that doesn't limit my size. I can still increase the size if I like. It jsut constrains the ratio.

And notice that it constrains the ratio even if I drag the bottom handle here or if I drag a side handle. So I no longer have free form control. You can also right-click inside the image and choose front image aspect ratio, which might make you think you're going back to the very original image, the one that I first opened a couple of movies ago, but that's not the case. If I choose that command or original ratio, Either one. I'll go ahead and choose this one, though, because it gives me numerical values.

I'll see these guys right here, 2505 by 1744 in my case. If you're working along with me, you may have different results. And that's actually the ratio of the last crop boundary I applied. And I know this because the very original image measured 3600 by 2400 pixels which is, by the way, 3 by 2. And I can access that by once again right clicking inside the image window and choosing 2 by 3 same difference.

But that is going to give me a vertical or a portrait shot. So I'll right click in the image and choose rotate crop box. That's the same as clicking on that little icon right there and notice that you have a keyboard shortcut of X. And I'll go ahead and drag this guy over a little bit like so, and then make the image bigger. Another option is to dial in a specific resolution, so I could right click inside the image window. And choose front image, down here.

Any of these options, by the way, is going to assign a resolution to your image, and that is going to modify the image size. So, in other words, you will resample the image, which I regard as very dangerous. So, I just want you to know this up front, and I'll demonstrate why. If I go ahead and choose front image. Just by way of example. And I'll make the crop boundary very small indeed and you can see, by the way. Notice this, this happens with the ratio as well, that you can switch between vertical and landscape just by dragging around.

But I'm going to go ahead and keep a landscape format. And drag the image into this area like so. And then I'll press the Enter key or the Return key on the Mac in order to apply that change. And notice there's a lot going on there because Photoshp had to think about it. And sure enough if I zoom in on this image to 100% you can see that it has been upsampled quite dramatically. And here's the kicker. It wasn't upsampled using Preserved Details, it was upsampled using By Cubic Smoother.

So it's the battled upsampling which I would encourage you to avoid. So I'll go ahead and press Ctrl+Z or Cmd+Z on the Mac in order to undo that change because you can see he used to be. Much smaller, and he deserves to be small as well, because he's in this big landscape setting. All right. So now let's say I drag with the crop tool, and I still have that same constraint at work, and I can see the constraint up here in the options bar. So I now have three values a width A height and a resolution. If you want to get rid of the resolution value, and just stick with a ratio, then you can switch back to ratio up here like so.

And, if you just want to clear the whole darn thing, you don't want any constraints at work at all, then just go ahead and click on the clear button in order to clear things out. And now, I once again have free form control. Over my crop, which is what I'm looking for. I'll show you just one more thing, because I think you'll find it handy. If you want to hide that portion of the image that appears outside the crop boundary, then just press the H key, and that'll go ahead and temporarily hide those pixels. They're still there, of course.

And then if you want to bring them back, you press the H key again. And you will once again see them. Now, the one thing that you don't want to do at this point is rotate the image some more. You don't want to do this number, because that would compound the destructive modifcation that we've already assigned in the previous movie, in other words, we'd be rotating on top of a rotation And that means that PhotoShop would have to once again, rewrite those pixels. Thankfully, I do have one undo, when I'm working with the crop tool so I can press Ctrl Z or Cmd Z on the Mac, in order to make the image upright again. And I drag down just a little bit like so and then I'll go ahead and accept this crop, which is now entirely non destructive by pressing the enter key or the returning key on the Mac, which.

For some reason I can't get it to work so I'll just go ahead and double click inside the crop boundary instead. So there you have it. That's how you constrain your crop boundary to a specific ratio, as well as how you clear that ratio so you can apply a freeform crop here inside Photoshop.
