How to work with Transforming and Retouching in Photoshop

Changing the size of the work canvas

Top

The Canvas Size command lets you add or remove work space around an existing image. You can also use the command to crop an image by decreasing the canvas area. In ImageReady, added canvas appears in the same color or transparency as the background. In Photoshop, there are several options for the background of the added canvas. If your image has a transparent background, the added canvas will be transparent.

To use the Canvas Size command:

  1. Choose Image > Canvas Size.
  2. Do one of the following:
    • Enter the dimensions you want the canvas to be in the Width and Height boxes. (Photoshop) Choose the units of measurement you want from the drop-down menus next to the Width and Height boxes.
    • Select Relative, and enter the amount by which you want to increase or decrease the size of the canvas. (Enter a negative number to decrease the size of the canvas.)
  3. For Anchor, click a square to indicate where to position the existing image on the new canvas.
  4. (Photoshop) Choose an option from the Canvas Extension Color menu:
    • Foreground to fill the new canvas with the current foreground color
    • Background to fill the new canvas with the current background color
    • White, Black, or Gray to fill the new canvas with that color
    • Other to select a new canvas color using the Color Picker

    Note: The Canvas Extension Color menu isn't available if an image doesn't contain a Background layer.

  5. Click OK.

Rotating and flipping entire images

The Rotate Canvas commands let you rotate or flip an entire image. The commands do not work on individual layers or parts of layers, paths, or selection borders.

    Rotating images A. Flip Horizontal B. Original image C. Flip Vertical D. Rotate 90 CCW E. Rotate 180 F. Rotate 90 CW

To rotate or flip an entire image:

    Choose Image > Rotate Canvas, and choose one of the following commands from the submenu:

    • 180 to rotate the image by a half-turn.
    • 90 CW to rotate the image clockwise by a quarter-turn.
    • 90 CCW to rotate the image counterclockwise by a quarter-turn.
    • Arbitrary to rotate the image by the angle you specify. If you choose this option, enter an angle between -360 and 360 in the angle text box. (In Photoshop, you can select CW or CCW to rotate clockwise or counter-clockwise.) Then click OK.
    • Flip Canvas Horizontal (Photoshop) or Flip Horizontal (ImageReady) to flip the image horizontally, along the vertical axis.
    • Flip Canvas Vertical (Photoshop) or Flip Vertical (ImageReady) to flip the image vertically, along the horizontal axis.

 

Cropping images

Top

Cropping is the process of removing portions of an image to create focus or strengthen the composition. You can crop an image using the Crop tool  and the Crop command. You can also trim pixels using the Trim command

 

Transforming objects

Top

You can scale, rotate, skew, distort, and apply perspective to entire layers, selected parts of layers, masks, paths, shapes, selection borders, and channels.

 

Retouching and repairing images

Top

You can use the Clone Stamp tool, Pattern Stamp tool, Healing Brush tool, and Patch tool to clone pixels and repair images.

 

Using the Liquify filter

Top

The Liquify filter lets you push, pull, rotate, reflect, pucker, and bloat any area of an image. The distortions you create can be subtle or drastic, which makes the Liquify command a powerful tool for retouching images as well as creating artistic effects.

The Photomerge command combines several photographs into one continuous image. For example, you can take five overlapping photographs of a city skyline, and then assemble them into a panorama. The Photomerge command is capable of assembling photos that are tiled horizontally as well as vertically.
