If you’re like most Photoshop users, you’ve probably noticed that your images can look a little off-kilter when they’re printed or displayed on a screen. This is usually due to vertical distortion, which is when the image appears to be leaning to one side or the other. Fortunately, there’s a quick and easy way to fix vertical distortion in Photoshop: just use the Distort tool (or one of its variations) and adjust the settings until the image looks straight again. Here’s how to do it:

  1. Open your image in Photoshop and select the Distort tool from the Tools palette.
  2. In the Distort dialog box, click on the Horizontal button and then adjust the slider until your image looks straight across.
  3. Click on the Vertical button and adjust the slider until your image looks straight up and down.
  4. If necessary, click on either of the other two buttons (Radial or Scale) to fine-tune your distortion settings even further. ..
