Creating motion blur isn’t as easy or always as possible as we might like when we’re just rushing to get the shot. Sometimes we’re not rushing, but thing aren’t moving in quite the way we’d hope. Or maybe we’re just not very good at shooting panning shots with a moving subject. Whatever the reason, it is possible to achieve a similar look in Photoshop. In this video, Photoshop guru Unmesh Dinda at PiXimperfect walks us through why we need perspective motion blur and how it differs from regular directional motion blur, as well as how to recreate the look on the computer within photoshop.
Regular directional motion blur is caused by the camera and subject moving differently to each other at a fixed distance. Perspective motion blur is caused when the camera and subject are moving towards or further away from each other during the exposure – like shooting from a moving vehicle. The environment gets smaller as it gets further away from you.
Both forms of motion blur are quite challenging to capture in-camera, but directional motion blur is fairly easy to simulate in post. Perspective motion blur is somewhat more difficult to produce. But the video above should get you pointed in the right direction. Do you create your motion blur in-camera or in post?
