这是一款基于安塞尔・亚当斯区域曝光法的摄影辅助工具，它将经典的 11 级灰度区域（Zone 0 至 Zone X）与现代相机曝光参数（光圈、快门、ISO）无缝结合，让你直观掌控画面明暗分布。

核心功能：通过 EV 值联动调整光圈、快门和 ISO，精准匹配目标区域，实现从纯黑到纯白的细腻控制。

创作价值：帮助摄影师摆脱 "自动曝光" 的束缚，像亚当斯一样主动规划影调，让每一张照片都拥有清晰的明暗层次和艺术表达。

使用场景：无论是风光、人像还是黑白创作，都能成为你精准控制曝光、塑造画面质感的得力工具。

This is a photography assistant tool rooted in Ansel Adams' iconic Zone System, seamlessly integrating the classic 11-tone grayscale zones (Zone 0 to Zone X) with modern camera exposure parameters (aperture, shutter speed, ISO). It empowers you to intuitively control the tonal distribution of your images.

Core Functionality: Dynamically adjust aperture, shutter speed, and ISO in relation to EV values, precisely matching your target zone and achieving nuanced control from pure black to brilliant white.

Creative Value: Free yourself from the limitations of auto-exposure and plan your image tones like Adams, ensuring every photograph boasts clear tonal hierarchy and artistic expression.

Use Cases: An indispensable tool for precise exposure control and texture shaping, whether you're shooting landscapes, portraits, or black-and-white photography.
