Keystone Correction – Easily Fix Leaning Buildings

with 9 Comments

It’s a common problem when shooting pictures of architecture… that annoying tilt… that “pinched” look near the top of your photo where it seems the buildings are leaning toward the center of the image. Sometimes that lean is slight, and sometimes it’s severe. It’s called the keystone effect.

Keystoning happens when you angle your camera upward to capture the top of a building. And some wide angle lenses can also produce the effect. It can ruin the look of your photo. But it doesn’t have to… it’s an easy fix in Photoshop Elements!

Tutorial:

For Adobe Photoshop Version click here.

Here’s how. First, open the image (File > Open) you want to work with…

Step One: Get to Know the Correct Camera Distortion Filter

  • In the Menu Bar, choose Filter > Correct Camera Distortion.
  • Down below your image, check the box next to Show Grid.

  • In the Perspective Control area of the settings box to the right of your image, adjust the Vertical Perspective slider until your building is no longer tilted. You may not be able to get it exactly 100% straight, but you can make a vast improvement.
  • Use the grid lines that appear over your photo to help align the edges of your buildings and straighten them up as you move the Vertical Perspective slider. You may or may not need to touch the Horizontal Perspective slider, depending upon your photo. Don’t mess with it unless you have to.
  • Next, move the Scale slider in the Edge Extension area to the left to zoom out a bit until you see your entire adjusted image on the blank background, and click OK.

Step Two: Crop Your Image Accordingly

  • Get the Crop tool and crop your newly straightened image.

What a difference!
