blur
Blur refers to a visual effect where an image appears unclear or indistinct. This can happen due to various reasons, such as motion, focus issues, or low light conditions. In photography, blur can be intentional, used to create artistic effects or emphasize movement.
In digital media, blur is often applied as a filter to soften edges or backgrounds, enhancing the focus on the main subject. Software like Adobe Photoshop allows users to adjust the level of blur, making it a versatile tool for graphic design and photo editing.
