Free Photoshop Tutorials: Content-aware scaling (CS4)
Version: Adobe Photoshop CS4
level: easyThis feature entered the world of photo editing algorithms a few years ago. Simply put, it enables magnifying or reducing photos without distorting any important elements (such as the main theme). Finally Adobe Photoshop CS4 also introduced such a feature last autumn. Let's see how it works out in a very obvious case.
Printer-friendly version
1. Load the photo
If you want to resize—for example, reduce—this picture, you have two choices: distorting its content, or making the whole picture proportionately smaller.
2. A transformable layer
One of the old methods is Transform, which also enables resizing.
If your photo is on a simple background layer, it is recommended to convert it to a normal resizable layer using Layer/New/Layer. Just click OK on the dialog that appears and you'll have an editable layer. You'll also need this step for content-aware scaling (discussed later).
