A short how-to on making a horizon level.

Step 1

Open an image with a horizon that’s not level. Instead of having to guess the angle to fix this at, here’s a short method that is lot more effective. You can use this image and save it to the computer and open in Photoshop.

Step 2

Click-and-hold the Eyedropper tool to pull out the menu. Click on the Ruler tool.

Step 3

Click-and-drag the Ruler tool along the crooked horizon.

Step 4

Go to Image>Rotate Canvas>Arbitrary.

Step 5

The degree of angle will be set to change the ruler to being level. Press OK.

Step 6

Now we have some areas to crop out. Select the Crop tool.

Step 7

Finally, we have a level horizon. We did change the composition though because areas had to be cropped out, so weigh the pros and cons before adjusting a horizon.
