Transcript:Make a Skewed Line Straight in Adobe Photoshop

Hi, I'm Don Shechter for About.com Computing.

Today, I'll show you how to straighten a skewed horizon line using Adobe Photoshop CS. Basically if your picture isn't straight, I will be teaching you how to fix it.

Choose a Picture for Photoshop Horizon Line Fix

First open Photoshop. Then open the picture you wish to adjust.

Make Straight Horizon Line in Photoshop

Select the Crop tool and make sure no numbers are entered into any of the fields in the Options bar.

Click and drag out a rectangle that is much smaller than the overall size of your image, but do not hit Enter and crop the picture yet.

Next, click inside the Crop Rectangle, and drag it so that either the top or bottom middle control handle is right on top of the horizon line.

In this image, we are using an actual horizon in the sky, but this will work for any picture. In those cases, you can use any line that should appear horizontal.

Move your cursor to the corner of the crop box, it will change to a curved double pointed arrow. Now click and drag to rotate the photo until the edge of your crop box is aligned with the horizon line.

Now drag out the sides of your crop box as much as you can. The corners of your original photo will be cropped out. Let's crop it by hitting Enter.

The result is a straight horizon in our picture.
