Hey gang this is Deke McClelland. Welcome to Deke's Techniques. Today I'm going to show you a really great use for a little known tool in Photoshop called the Perspective Crop Tool. So here's the idea I captured this photograph of the aftermath of playing a classic 1970s board game called Landslide where you run for president of the United States. But I actually captured the photo like this. And you can tell that's the case because there are my feet after all. I'm perched on a bench looking down at the table and naturally because I'm to the side of the table a little bit I'm getting perspective in the scene.
So the front of the table is optically larger than the back and the slots of wood in the table are perched at various different angles. That's not what I want. What I want is this head on view of the scene. It's as if I am suspended directly above the table capturing the scene by looking downward at it. And as a result every single slot of wood is exactly vertical and that is an effect you can achieve using the Perspective Crop Tool as I'm about to show you right now.
Alright, let's get started. The first step is to go up to the File menu and choose the Open command or of course you can press Control > O or Command O on a Mac. And the you want to locate this image right here. It's called Landslide_DM39922.dng. The DNG tells you that this is a digital negative file. So, it's a raw file in other words. And the file name by the way was automatically assigned by the digital camera with the exception of the word landslide right there. Alright, I'm going to go ahead and click the Open button.
Because this is a raw image it's going to open automatically inside of Camera Raw. Now presumably you'd want this to be a Smart Object so that you can come back and modify the Camera Raw settings later. And to make that happen you would go ahead and press the Shift key so that the Open image button becomes an Open Object button and then go ahead and click on it in order to as I say open that raw image as a Smart Object. And you can see that it's appearing as a Smart Object because of this little page icon here inside the layers panel.
If I go ahead and zoom in by let's say pressing Ctrl+1 or Cmd+1 on a Mac zoom in to 100%. And I'll go ahead and scroll up to the top of the image. You can see that it's out of focus up in this region because of the fairly shallow depth of field that was at work when I shot this photograph. However if we move down a little bit to this region that goes by the name of the south in the game Landslide you can see that we have a little bit of motion blur. So you might be tempted to sharpen it up inside Camera Raw and you can do that by double-clicking on the thumbnail for this image here inside the layers panel.
And because you have a Camera Raw Smart Object that'll open up things inside of Camera Raw. And you can now go ahead and zoom in down here in the lower left corner to 200% let's say. And then I'll just go ahead and Space bar drag the image down a little bit so I can see once again the southern region of the United States. Now you may notice over here in the Basic panel that I've already made some modifications that suite this specific image in advance. I'm going to switch over to the Detail panel which is three icons over up here. And I'm going to crank the sharpening amount value all the way up to 150% so you can see that we've got this kind of wormy texture that's going.
That's a function of the Detail slider right there. But it also shows me that I have some noise at work. So what I'm going to do is take that luminous noise value up to 50% and then I'll press the Tab key. And you can see that, that goes ahead and settles down the noise quite a bit actually. Now when we're working with motion blur like this meaning that there was a little bit of camera shake because this is a handheld shot you don't want to apply a ton of sharpening inside of Camera Raw. In fact you want to take that value down to its default which is 25% and then leave the radius set to one a detail of 25 is fine for this image.
And then go ahead and click OK in order to apply that change. And you will not see a very subtle transformation on screen here. I'll go ahead and zoom in so we can see it better. This is before we made that change so this is the noisier version of the image. And if I press Ctrl+Z or Cmd+Z on a the Mac in order to reapply the change you can see the Camera Raw has gotten rid of a lot of that noise. Alright, now let's turn our attention to perspective crop. I'll go ahead and zoom out by pressing Ctrl+0 or Cmd+0 on a Mac so that I can see the entire image.
There are my feet popping out right there want to get rid of those obviously and we want a head on shot of the table. So I'll go over to my Crop tool click and hold on it and I'll choose the Perspective Crop Tool from the Flyout menu. Then if you so much as click inside of the image you're going to get this alert message that tells you that the Perspective Crop Tool doesn't work with Smart Objects is the problem. It only works with pixel-based layers. So go ahead and click OK. There's no way around that. This is a destructive tool so what you have to do is right-click inside the image and choose Rasterize Smart Object in order to convert it to a standard image layer.
Which means from this point on you can no longer double-click on a thumbnail to open up your settings once again inside Camera Raw. But now that it's a standard pixel based layer I can go ahead and drag inside of it using that Perspective Crop Tool. Now what you want to do is drag these corners to the desired location. So notice that all four of the corners move independently like so. But I want to make sure that I can really see what I'm doing so I'm Ctrl+Space bar clicking that's a Cmd+Space bar click on a Mac in order to temporarily access the Zoom Tool there.
And then at 100% I'll go ahead and drag this corner up like so, so that it's on the inside edge of the table. And then I'll go ahead and space bar toss the image over to this location to the left and I'll drag this guy up to this inside edge corner. Again we're going to be cropping away some of the cards I'm not worried about that. Then I'll go ahead and toss the image down until I arrive at this upper left location and I'll drag this corner into there. And then I'll go over to the upper right corner if I can find it there it is and I'll drag this guy down to this location.
And then I just happen to know from experience I am scrolling down a bit as you can see that I need to scoot this edge in this right edge inward just a little bit in order to avoid some highlights over on the side. Alright, now press Ctrl+0 or Cmd+0 on a Mac to zoom out so we can see the entire thing. And then to apply the crop notice that you don't have any options for not deleting the pixels so you always delete pixels with this tool. So once you're sure that you have everything the way you want it you can go ahead and click on the check mark up here in the Options bar or you can just press the Enter key or the Return key on a Mac.
And just like that we've gone ahead and squared off the image. So it's as if I'm hanging directly above the table taking this shot. Which of course would have been at best inconvenient. Alright, now I'm going to switch over to the Crop tool, the Standard Crop Tool. And because I was posting this image on Facebook, Facebook likes squares by the way, square images. That's how you're going to get the most out of your real estate. And so, I went up to the Options bar here and changed ratio to one to one square and then click inside of the crop boundary just to make sure it's active and now you can drag the image upward like so.
You don't want to drag it too much side to side because you'll pull the sides away which isn't what we're looking for. And I'm going to go ahead and drag this guy up on Space bar dragging down so I can see more of the image. And I just want to make sure that this Florida card is entirely cropped out because after all these cards up above are so very blurry. And that way we can see a little bit of New Hampshire down here at the bottom this little red card. And now at this point I'll go ahead and press the Enter key or the Return key on a Mac. Actually I'll do one more thing. Delete Crop Pixels is turned on by default.
I don't know why that is. But anyway we don't want that. Go ahead and turn that check box off. Whenever you're working with layer in particular you want to keep those pixels if you can. Then press the Enter key or the Return key on a Mac in order to apply that change. And then you can make sure that you haven't lost any pixels by switching to your Move Tool and then you can drag the image around and you can see that there's much more image available to you. I'm going to press Ctrl+Z Cmd+Z on the mac however and then I'll just go ahead and zoom in. Press the F key a couple of times and you can see now if I press Ctrl+0 or Cmd+0 again just make sure everything's centered.
You can see that we now have a squared off image thanks to our ability to remove the perspective from the scene using the Perspective Crop Tool here inside Photoshop. If you're a member of the www.lynda.com Online Training Library then I have a follow up movie in which I show you how to reduce the effects of camera shake using the Shake Reduction Filter. And as you can see here it's pretty darn complicated looking anyway but we will make sense of it. If you're waiting for next week's free movie I'll show you how to get rid of the effects of reflected light this glare in the lower left corner of the board.
We're going to remove it entirely as you see here in post in Photoshop. Deke's Techniques each and every week. Keep watching.
