不經不覺,期待一年的努力有了成果,這個撇除陰天和下雨日子(今年都幾多!),要求約每星期同時間(我選了上午七時半上班前)拍一至兩天的 project ,話易又不易,說難又不太難,但在好奇心驅使看「最期待的畫面」大前題下,在本年「冬至」來到後,終於看到香港版太陽 8 字日行跡和太陽在廿四節氣的位置!

拍攝這令我更了解大自然的奥妙,知道太陽在「冬至」移到最南(日至南),「夏至」移到最北,二分(「春分」,「秋分」)時太陽(約)在正東升起,正西落下。亦為攝影朋友為何夏丶冬季會說太陽「唔啱位」影響攝影構圖的原因。

祝各位讀者新年進步!

***

The figure-8 shaped curve was taken as the path of the Sun at 07:30am (HKT, UTC+8) in the year 2014, highlighting with the 24 solar terms.
Due to cloudy or rainy days, the image may be taken before / after the solar term day and are marked +/- nd(ays).

That year's two equinoxes on March 21 (0° longitude) and September 23 (180° longitude) correspond to the mid-points but not the cross-over point, on the curve.

While summer solstice on June 21 (90° longitude) and winter solstice on December 22 (270° longitude) are located at the top-left and bottom-right on the curve respectively.

Wish you all a Happy New Year!
