Some of the presets are designed for print, others for the web or on-screen viewing in general.
There's also options for saving and loading our own presets. There's some potential problems and pitfalls you can run into when choosing preset image sizes, though, like the fact that some presets have different aspect ratios than others, so we'll look more closely at this option in another tutorial:.
Shortcodes, Actions and Filters Plugin: Error in shortcode [ ads-essentials-middle ]. Below the Fit To option, we find three very important options - Width , Height and Resolution - that together make up the main image resizing section of the dialog box:. We can enter new values into the Width and Height boxes. When we change the value in one of them, Photoshop automatically changes the other to preserve the original aspect ratio of the image.
By default, the measurement type for both the Width and Height is set to Inches, but if you click on the measurement type selection box for either option, a menu will appear with other measurement types to choose from. Notice that at the moment, the Pixels type is grayed out and unavailable. We'll learn why that is in another tutorial when we look at the difference between resizing and resampling an image:. The Resolution option works the same way. I'll cover everything you need to know about image resizing in the next tutorial, but briefly, the term resizing simply means changing the size at which the image will print, without changing the actual number of pixels in the image.
For example, currently the Dimensions section at the top of the dialog box is showing that my image has pixel dimensions of x That's because we'll be fitting of the image's pixels from top to bottom and pixels from left to right inside every inch of paper:. Again, this is just a brief overview of image resizing.
We'll cover it in more detail in the next tutorial:. Below the Resolution option is the Resample option which can be enabled or disabled by clicking inside its checkbox. Up until now, it's been disabled, so I'll go ahead and enable it:. The Resample option changes the behavior of the Image Size dialog box. The term resampling means changing the actual number of pixels in the image, not just its print size, to make the image itself larger or smaller.
With this option enabled, the Width and Height options can now display the width and height of the image in pixels unlike earlier when the pixels measurement type was unavailable :. We can now change the actual number of pixels in the image by entering new values into the Width and Height boxes.
By default, Photoshop again keeps the original aspect ratio the same, so if I enter a new value of, say, pixels for the width, Photoshop automatically changes the height to pixels to match the original ratio. If we look up at the top of the dialog box, we see that the Dimensions section is also showing my new image size of px x px, and above it, the Image Size section is telling me that the file size, in megabytes, has dropped from its original Also with the Resample option enabled, you'll find a clickable link icon between the Width and Height options.
This is the Constrain Proportions option, and it's enabled by default. This is what tells Photoshop to keep the original aspect ratio of the image intact by automatically entering the correct height value when we change the width or vice versa. In most cases, you'll want to keep this option enabled, but disabling it will allow you to enter separate values for both the width and height at the risk of changing the aspect ratio and distorting the look and shape of the image:.
Another very important option that only becomes available with the Resample option enabled is Image Interpolation , which refers to the method Photoshop uses for adding or removing pixels in the image. The interpolation method we select can have a dramatic impact on the quality and appearance of your image after it's been downsampled made smaller or upsampled made larger.
The interpolation option is located directly to the right of the Resample option. It doesn't actually say "Image Interpolation" anywhere, but it's the option that, by default, is set to Automatic :. Clicking on the word Automatic will open a list of interpolation methods to choose from, including a brand new one in Photoshop CC, Preserve Details , designed to keep our images looking crisp and sharp when enlarging them.
In fact, if we leave the interpolation option set to Automatic, Photoshop will automatically select Preserve Details when it detects that we're enlarging the image. When downsampling reducing the size of an image, the Automatic option will choose Bicubic Sharper for the best results. The preview window will update to show you what the image will look like as you select different interpolation methods.
We'll look at these options in more detail in the full image resampling tutorial, but for now, leaving this option set to Automatic is a safe choice:. If you're using any layer effects styles in your document, like drop shadows, strokes, bevel and emboss, and so on, you'll most likely want the effects to scale in size along with the image.
