One of the slickest new features of Adobe Photoshop CS4 is Content Aware Scale. If you’ve ever wanted to turn a horizontal image into a vertical, without damaging key parts of the image, this is for you!
Step 1: Open your image and double-click on Background layer to turn it into Layer 0.
Step 2: Go to Image > Canvas Size to add space where you want to scale to.
Step 3: Go to Edit > Content Aware Scale and transform the image into the empty space.
When skintones become distorted, you need to choose Protect Skintones from the Control Panel (formerly the Options Bar)
Step 4: You may notice that some areas aren’t working well, so Undo (or press ESC) and go back to Edit > Content Aware Scale. Now on the Control Panel (formerly the Options Bar) click on the icon that looks like a Mens’ room icon and now transform your image.
Step 5: If this still isn’t giving you the results you’re looking for, you can take it a step further by creating an Alpha Channel. Make a selection out of the area you don’t want scaled. Go to Select > Save Selection, which will give us an Alpha Channel we can use to protect this area.
The Alpha Channel allows you to designate specific areas not to be transformed.
Step 6: Choose Edit > Content Aware Scale, and from the “Protect” pull down menu on the Control Panel, select the Alpha Channel you just made.
Step 6: The "Protect" pull down menu allows you to use an Alpha Channel to keep areas from being transformed.
Step 7: Drag the handles, and decide if you need to go back to the Alpha Channel and add more white (the protected area) to that channel.
And voilà ! Photoshop transforms the areas that aren’t part of the channel! Not every photo works well with this technique, but when it works, it’s a lot of fun!
