照片背後的故事
The story behind Mirror Reflection
「塞翁失馬」般的拍攝意外
那天厷金瓜寮溪，是想拍另一種題材。結果原計畫沒成，正準備收工的時候，看到一隻清溪蟹站在淺水石頭上，水面平滑得像一面鏡子。
趴下去從低角度看出去——眼前那一刻就出現這個畫面：水面下一隻蟹、水面上是同一隻蟹的完整鏡像，比例一致、姿態對稱。乍看是兩隻蟹彼此對峙，實際上是同一個個體。
看似「兩隻」，其實是「一隻」
這張照片在比賽提交、媒體報導、網路討論中，最常被問的就是這句：「真的是一隻嗎？」
是。這是水面的全反射（total internal reflection 在這個角度下接近完全）。當水面靜止、下方的蟹貼近水面、相機以極低的角度拍攝，鏡像幾乎與本體 1:1 對稱，乍看會誤以為是兩個體在對望。
有趣的是，越是仔細看，越惨看出細節差影——例如水下原本被水光調整過的色彩，與水面上反射光線的微妙偏移。
Ocean Art 2022 — 人像組世界冠軍
這張作品獲得 Ocean Art Underwater Photo Competition 2022 人像組第一名（Gold）。Ocean Art 是全球規模最大、參賝國家最多的水下攝影比賝之一，由 Underwater Photography Guide 主辦，每年從上百個國家收件，得主公布後會成為當年水下攝影界的重點討論。
金牌的意義在於——這是「世界冠軍」級的肯定。同一個分組沒有更高的獎項。
從台灣的溪流，到世界的舞台
這張照片的另一層意義，是它拍的不是熱帶珊瑚礁、不是知名潛點——而是台灣在地的溪流，台灣特有種清溪蟹。
很多人以為「世界級的水下攝影」必須要去某個遙遠的國家。其實未必。觀察夠細、技術夠好，台灣本地的水域也能拍出世界第一。
A "blessing in disguise" kind of shooting accident
I went to Jinguashi Stream that day to shoot a different subject. The original plan didn't work out, and just as I was packing up, I noticed a stream crab perched on a rock in shallow water — and the water surface was utterly still, like a sheet of glass.
I dropped down to a low angle, and the frame appeared instantly: a crab below the surface, the same crab's full mirror image above it, proportions matched, postures symmetrical. At first glance it reads as two crabs facing each other. It's actually one.
Looks like "two crabs". It's one.
Through the competition submission, the press coverage, and the online discussions afterward, the question I've been asked the most is: "Is that really one crab?"
Yes. The phenomenon is the water surface acting as a near-perfect mirror at this angle (total internal reflection close to ideal). When the water is still, the crab is close to the surface, and the camera is at an extremely low angle, the reflection becomes near 1:1 with the subject — easy to mistake for two individuals confronting each other.
The tell, if you look closely, is in the color and lighting differences — the underwater half is shaped by the water column, the reflected half carries the airside light's subtle shift.
Ocean Art 2022 — Portrait World Champion
This image won 1st Place (Gold) in Portrait at the Ocean Art Underwater Photo Competition 2022. Ocean Art is one of the largest underwater photography competitions globally, hosted by Underwater Photography Guide and drawing entries from over a hundred countries each year. The winners are a focal point of the underwater photography year.
Gold here means "world champion" in this category — there's no higher placement in this division.
From a Taiwan stream to the world stage
The other layer of meaning in this image: it wasn't shot in a famous tropical reef or a well-known dive site. It was shot in a Taiwan stream, with a Taiwan-endemic stream crab as the subject.
Many people assume "world-class underwater photography" requires traveling to some far-off destination. It doesn't have to. With sharp enough observation and competent technique, local Taiwan waters can produce a global gold medal.
