exposure-dual-control

用户在纠结光圈和快门速度的选择、问"怎么设置曝光参数"、或想理解曝光的创造性效果时调用。 不适用于测光表使用问题（应调用 light-meter-compensation）、胶片选择问题、或纯器材参数查询。 Invoke when the user is deciding between aperture and shutter speed, asking about exposure settings, or wants to understand the creative effects of exposure. Not for light-meter usage (use light-meter-compensation), film selection, or pure gear spec queries. 关键 trigger / Key triggers: "光圈快门怎么设"、"曝光参数"、"aperture shutter speed"、 "景深怎么控制"、"运动模糊"、"exposure settings"、"how to set exposure"、 "aperture vs shutter speed"。
