This is especially useful for macro, portrait, and other scenarios that require precise focusing. Exposure Preview Adjustment: Supports real-time preview of exposure compensation. When adjusting parameters, brightness changes in the image are displayed synchronously, allowing users to intuitively evaluate the exposure effect and restore the true lighting.
