Getting your photos straight is one of the basic requirements of photography. Crooked horizon lines in landscapes and architecture photos where the horizontal lines in buildings lean towards one side are a real show stopper. The first thing you should always try to achieve is to get straight images straight out of your camera. Use spirit levels and align your shots carefully from a tripod. But in some cases, this is not possible or you have only limited time, or you’re forced to shoot hand-held.
This can result in photos that are not only rotated but distorted in complex ways with rotation around the roll, pitch and yaw axes. The effect is that the sensor plane is not parallel to the lines in the actual scene.
In this video tutorial, I am showing you
- How to correct such a complex distortion in post-processing by using the Transform tools in Photoshop.
- How to correct slight asymmetries using the Puppet Warp tool in Photoshop.
Make sure you watch the video in HD 1080p mode to see all the details.
