From golden-hour glow to deep twilight — estimate lux and get a starting point for ISO, aperture and shutter speed.从黄金时刻的光辉到深沉的暮色——估算照度，并获得 ISO、光圈与快门速度的起步参数。
- Pick the date and time you plan to shoot — the tool estimates the light level from the sun's altitude.选择计划拍摄的日期与时间——工具会根据太阳高度角估算光照度。
- Read the suggested ISO / aperture / shutter combinations as a starting point.将建议的 ISO / 光圈 / 快门组合作为起步参数。
- Bracket: take one shot at the suggested value, one stop under and one over, then choose in post.包围曝光：按建议值拍一张，再各欠曝过曝一档，后期再选择。
These are estimates from astronomy, not metering. Your scene's actual reflectance matters — snow and beach read brighter, forests darker. Use the table as the baseline, then trust your histogram.这些是基于天文学的估算，不是测光。场景实际反光率很重要——雪地与海滩偏亮，森林偏暗。把表格作为基线，然后相信直方图。
