Blue Sky

Circular Polarizing Lens filter, or CPL, is an invaluable tool for landscape photographers.  It is one of the rare tools which cannot be replicated in the post processing.  It can make the skies bluer, the seas clearer with better contrast.

The way it works is they align the light rays getting through the filter onto the sensor, and can reduce the refraction from the dust particles in the air, and also works on the water reflection.  These effects cannot be reproduced by Photoshop.  So I highly recommend budding landscape photographers to bring along 1 CPL with you next time you go shoot.  Depending on the diameter of your lens and also the quality of the filter, price varies from around HKD400 (USD50) to HKD1200 (USD180) for the top notch ones, e.g. B&W.  Try it out and you will never leave home without it.

照片的結構(一)

首先,在開始分析之前,我們要知道一張照片的結構大致上可以分成三個層次:

  1. 表面內容
  2. 構圖手法
  3. 故事

今天我們先談談第一點: 表面內容。

好像左面那幅照片,我捕捉了一個衣著整齊的公安在則目。在背景裏看見巨大的毛澤東肖像,加上牆壁特別的橙紅色告訴我們拍攝的場地正是北京的天安門廣場。

為什麼要那麼詳盡地形容呢?因為我認為在每張作品裏,攝影者都應該清楚知道自己在拍攝什麼。無論在構圖時、按快門時、或是後期剪裁(crop)時,都應該注意影像裏包含了什麼;不單只是主體,還有散景裡都要留意,才能明確地表達自己的想法。
