Photoshop’s 3D features will be removed in future updates. Users working with 3D are encouraged to explore Adobe’s new Substance 3D collection, which represents the next generation of 3D tools from Adobe.

Content-Aware Scale resizes an image without changing important visual content such as people, buildings, animals, and so forth. While normal scaling affects all pixels uniformly when resizing an image, content-aware scaling mostly affects pixels in areas that don’t have important visual content. Content-Aware Scale lets you upscale or downscale images to improve a composition, fit a layout, or change the orientation. If you want to use some normal scaling when resizing your image, there is an option for specifying a ratio of content-aware scaling to normal scaling.
If you want to preserve specific areas when scaling an image, Content-Aware Scale lets you use an alpha channel to protect content during resizing.
Content-aware scaling works on layers and selections. Images can be in RGB, CMYK, Lab, and Grayscale color modes as well as all bit depths. Content-aware scaling doesn’t work on adjustment layers, layer masks, individual channels, Smart Objects, 3D layers, Video layers, multiple layers simultaneously, or layer groups.

Reference Point Location
Click a square on the reference point locator to specify the fixed point around which the image is scaled. By default this point is at the center of the image.
Use Relative Positioning For Reference Point
Click the button to specify the new position of the reference point in relation to its current position.
Reference Point Position
Positions the reference point at the specific location. Enter X-axis and Y-axis pixel dimensions.
Specifies the image scaling as a percentage of the original size. Enter a percentage for the width (W) and height (H). If desired, click Maintain Aspect Ratio .
Specifies the ratio of content-aware scaling to normal scaling. Specify a percentage for content-aware scaling by typing in the text box or clicking the arrow and moving the slider.
Chooses an alpha channel that specifies an area to protect.
Protect Skin Tones
Attempts to preserve regions that contain skin-tones.
