Photographer's Note
The beam of light from Gibbs Hill Lighthouse runs 362 feet above sea level. Ships 40 miles away can see its light. Its flash can be spotted by planes flying at 10,000 feet 120 miles away. The original light back in 1846 was produced by a concentrated burner of four circular wicks. This was replaced in 1904 with a five wick burner using a glass chimney, which was operated until 1923, when a kerosene burner was installed. This vapour burner system gave way to electricity in 1952.
The Light is now supplied by a 1,000-watt electric bulb which is located in the center of the lens. Until 2004, the lens revolved around the light in a trough containing 1,200 pounds of mercury and weighed two and three quarter-tons. In September 2003, the oscillation of the tower during Hurricane Fabian caused two gallons of mercury to slop out of the lens support trough and put the light out of operation. The 1904 lens was repaired in 2004 with steel bearings to replace the mercury. Consisting of a series of concentric prisms, the present lens is capable of building the light up to a half million candle power. The lens makes a complete revolution once every 50 seconds, resulting in a flash of two seconds duration at every ten-second interval.
Fresnel Mercek
Gibin Tepesi Deniz Feneri'nden gelen ışın, deniz seviyesinden 362 ayak yükseklikten çıkar. 40 mil ötedeki gemiler ışığını görebilirler. Işıltısı, 120 kilometre uzaktaki 10,000 ayakta uçan uçaklar tarafından fark edilebilir. 1846'daki orijinal ışık, dört yuvarlak fitilli konsantre bir brülör tarafından üretilirdi. Bu, 1904 yılında, 1923 yılına kadar çalıştırılan bir kerosinli brülör kurulduğunda, cam bir baca kullanarak beş fitilli bir brülör ile değiştirildi. Bu buhar brülörü sistemi 1952'de elektriğe geçti.
Işık şimdi merceğin merkezinde bulunan 1.000 watt'lık elektrik ampulüyle sağlanmaktadır. 2004'e kadar mercek 1.200 libre cıva içeren bir yalakta ışığın etrafında dönerdi ve iki ve üç çeyrek ton ağırlığındaydı. Eylül 2003'te, Kasırga Fabian sırasında kulenin titreşimi iki galon cıvanın mercek destek yalağından dökülerek ışığı devre dışı bıraktı. 1904 merceği, cıva yerine çelik rulmanlarla 2004 yılında onarıldı. Bir dizi eşmerkezli prizmadan oluşan mevcut mercek, ışığı yarım milyon mum gücüne kadar yükseltebiliyor. Mercek, her 50 saniyede tam bir devrim yapıyor; bu da her on saniyelik aralıkta iki saniyelik bir ışıltıya sonuç veriyor.

Bonjour, cher Murat,
La note est parfaite pour rappeler le fonctionnement d'un phare et de son système mis en place au cours du temps.
L'image est une réussite et l'on prend plaisir à regarder cette mécanique ingénieuse.
Amitiés.

Hello Murat,
That sounds like quite a strong light. Excellent close-up photo of the lens, I really like the many different patterns of the old design of the lighthouse we can see.

Hello Murat,
Interesting story to accompany this interesting composition. I like the choice of black and white and the symmetrical, both of which serve to put the emphasis on the subject.
You were right to surmise that I used pseudo-HDR in my composition of the bridge. The sky was otherwise rather boring.

Hi Murat,
Very interesting view of this classic lighthouse lens system. Such views are not commonly available in many places. B&W fits well on this theme. Your note gives excellent description of the system and it's history.
