Here, we're going to look at another important preference which is located inside of the General tab. The preference we're going to focus in on is called Image Interpolation. Now I know that word or those words may sound a little bit funny, but what this has to do with is the way that we work with our photographs which are made up of pixels. How do we want Photoshop to handle these images, all of these pixels when were resizing or changing the size of those pictures? You know, in the previous versions of Photoshop, what we had to do was we had to select between Bicubic Smoother--which was better when we were increasing the size of our pictures--or Bicubic Sharper, which worked better when we were decreasing the size of our photographs.
Well, now we have this new preference, which is Bicubic Automatic. In other words, Photoshop will automatically choose the best type of image interpolation. So why does this matter? Well, this matters because this will help us to make our images look their best. And by choosing this preference here, Photoshop will then take advantage of this or use this in a few other places as well. Let me show you what I mean. Let's go ahead and select that option and then click OK. Next, in our Layers panel, let's double-click this Background layer. That will unlock the layer so that we can free transform it.
So if you double-click the layer name, you notice it opens up this layer dialog. I'll just name this BG for background and then click OK. Well, now this layer is unlocked. The next thing I want to do is free transform this. To do that, we can navigate to our Edit pulldown menu. About halfway down or so, you'll notice there's an option for Free Transform. Well, the reason why I'm going here is that once you activate this tool, you can see we have new options in our Options bar. All the way down at the end we have Image Interpolation options.
Here, you can see that we click on this, whatever we dialed in our Preferences dialog will be chosen here as the default setting, Bicubic Automatic. And this is great because, therefore, as I change the size of my photograph-- either decreasing or increasing the size of this image--it will then choose the appropriate image interpolation. Well, let's say, we want to increase this a little bit. All that we need to do is to click and drag that out and then press Enter or Return in order to apply that. Another location where we'll see the show up has to do with image sizing.
We'll be talking about image sizing much more later, but for now I just want to highlight this. If you navigate your Image pulldown menu, you can then select this option, Image Size. This will open up the Image Size dialog. You'll notice that at the base of the dialog, it will select for you Bicubic Automatic. And again, it's choosing that option because we dialed in that preference inside of the General tab of the Preferences panel. And this option--again it is critical-- it's really important when it comes to working with photographs and also when it comes to resizing or changing the dimensions of your pictures.
So again, back in your Preferences dialog, you want to make sure that you have that Bicubic Automatic preference turned on so that that will be the default image interpolation option as you work in Photoshop.
