Default refers to the factory settings pre-configured by a manufacturer for a piece of hardware or software. These settings are designed to provide a reliable and stable starting point for users, ensuring the device or application works correctly out of the box. In photography, default settings may apply to camera menus, editing software, or image processing options. While users can customise these settings to suit their workflow, they can usually be reset back to default if problems occur, making it easier to troubleshoot and maintain consistent performance.
