How to make an unclear license plate readable

In this article, we will provide step-by-step instructions on how to make a blurry license plate in a photo or video readable.

When dealing with a getaway car caught on camera or a hit-and-run incident, knowing the license plate number can be a big advantage for investigators in uncovering the identity of their suspect. However, environmental factors, like low lighting or poor camera quality, can lead to an image of a license plate being illegible. Using CaseGuard’s enhancement effects, a readable license plate number is just a few clicks away.
