Dutch maritime memories


The Dutch East India Company was a chartered company established in 1602, when the States- General of the Netherlands granted it a 21-year monopoly to carry out colonial activities in Asia. It is often considered to have been the first multinational corporation in the world and it was the first company to issue stock.

Statistically, the VOC eclipsed all of its rivals in the Asia trade. Between 1602 and 1796 the VOC sent almost a million Europeans to work in the Asia trade on 4,785 ships, and netted for their efforts more than 2.5 million tons of Asian trade goods. By contrast, the rest of Europe combined sent only 882,412 people from 1500 to 1795, and the fleet of the English East India Company, the VOC’s nearest competitor, was a distant second to its total traffic with 2,690 ships and a mere one-fifth the tonnage of goods carried by the VOC. The VOC enjoyed huge profits from its spice monopoly through most of the 17th century.
Having been set up in 1602, to profit from the Malukan spice trade, in 1619 the VOC established a capital in the port city of Batavia (now Jakarta). Over the next two centuries the Company acquired additional ports as trading bases and safeguarded their interests by taking over surrounding territory. It remained an important trading concern and paid an 18% annual dividend for almost 200 years.

Canal-Belt amsterdam



Amsterdam, capital of the Netherlands, has been called the "Venice of the North" for its more than one hundred kilometres of canals, about 90 islands and 1,500 bridges.
 The three main canals, Herengracht, Prinsengracht, and Keizersgracht, dug in the 17th century during the Dutch Golden Age, form concentric belts around the city, known as the Grachtengordel. Alongside the main canals are 1550 monumental buildings. The 17th-century canal ring area, including the Prinsengracht, Keizersgracht, Herengracht and Jordaan, were placed on the UNESCO World Heritage List in 2010.
Much of the Amsterdam canal system is the successful outcome of city planning. In the early part of the 17th century, with immigration at a height, a comprehensive plan was put together, calling for four main, concentric half-circles of canals with their ends resting on the IJ bay.

Mirror image



A flipped image or reversed image, the more formal term, is a static or moving image that is generated by a mirror-reversal of an original across a horizontal axis (a flopped image is mirrored across the vertical axis.
Many large format cameras present the image of the scene being photographed as a flipped image through their viewfinders. Some photographers regard this as a beneficial feature, as the unfamiliarity of the format allows them to compose the elements of the picture properly without being distracted by the actual contents of the scene. The technique is meant to bypass or override the brain's visual processing which normally sees what is expected rather than what is there.
Flipping is occasionally used as a trompe l'oeil effect in scenes which incorporate reflections in a body of water. The image is deliberately inverted so that people slowly discern that something is 'not quite right' with the picture, and come to notice that it is upside down.

Dive devil




Today, the small size of fully automatic camcorders with large view screens and long-life rechargeable batteries has reduced the housing size and made underwater videography an easy, fun activity for the diver. Low-cost wide-angle lens add-ons are available for many cameras and some can even be fitted outside the camera housing for versatile use. This lets the photographer get closer and make the subject clearer and also with fewer focusing and depth of field problems.
Today cameras are more sensitive to low light conditions and make automatic color balancing adjustments. Nevertheless, deeper water videography still needs auxiliary light sources to bring out colors filtered out of sunlight by the distance it has travelled through water. The longest wavelengths of light are lost first (reds and yellows) leaving only a greenish or blue cast in deep water. Even a hand light will help show off some of the magnificent colors of a coral reef or other marine life if used during recording.
