Longest & Shortest Day最长与最短日照日
Which day has the most light and which has the least — for your exact latitude.哪一天光照最长、哪一天最短——针对你的精确纬度。
- Set your latitude — day length depends almost entirely on latitude, not longitude.设置你的纬度——日照时长几乎只取决于纬度，与经度无关。
- Read the longest and shortest days of your year, and compare with today.查看一年中最长与最短的一天，并与今天对比。
- Plan around them: near the solstice, golden hour timing barely changes for weeks — great for repeating shoots; near the equinox, times shift up to 3 minutes a day.据此规划：二至日前后黄金时刻数周几乎不变——适合重复拍摄；春秋分前后每天变化可达 3 分钟。
At 60° latitude (Oslo, Anchorage) the longest day lasts ~19 hours and summer golden hour stretches for over 2 hours — while at the equator every day is ~12 hours with a tight 50-minute golden hour. Latitude is the single biggest lever on your shooting calendar.在北纬 60°（奥斯陆、安克雷奇），最长白天约 19 小时，夏季黄金时刻超过 2 小时；而在赤道，每天约 12 小时，黄金时刻只有约 50 分钟。纬度是影响拍摄日历的最大杠杆。
