| Inscription | Horloge (haut): SHEPHERD PATENTEE // 53 LEADENHALL ST(T) LONDON // GALVANO-MAGNETIC CLOCK
Plaque commémorative (gauche): The Shepherd 24-hour Gate Clock // This is one of the earliest electrically driven public clocks and was installed here in 1852. The dial always shows Greenwich Mean Time (GMT). In summer Britain converts to British Summer Time (BST), which is an hour ahead of GMT, and the clock then appears one hour 'slow'. Being 24-hour clock, the hour hand marks noon (XII) at the bottom of the dial and midnight (0) at the top. The time shown is accurate to 0.5 of a second. // The Time Ball // The red time ball on top of Flamsteed House is one of the world's first visual time signals. It was installed in 1833 (though the present one dates to 1919) to enable navigators on ships on the Thames to check their marine chronometers. The Time Ball drops daily at 1300hrs (GMT in winter, BST in summer). It is raised halfway up the mast at 1255hrs as a preparatory signal and to the top 2 minutes before it drops. Plaque commémorative (partie centrale): Height above Mean Sea Level at Newlyn 154.70 feet.
Plaque commémorative (droite): Ordnance Survey Bench Mark // The small plate (marked 'G 1692') is an Ordnance Survey bench mark. Similar marks appear on walls and buildings across the country. The height of each above sea level has been measured and recorded. Dating from the 1940s, this particular mark is a replacement for an older mark that once existed nearby. // Public Standards of Length // These British Imperial Standards were first mounted outside the Observatory main gates some time before 1866, to enable the public to check measures of length. The stated length is the distance between the inner faces of the two D-shaped studs. Jauge (bas): BRITISH YARD // TWO FEET // ONE FOOT // SIX INCHES // THREE INCHES // TROUGHTON & SIMMS LONDON
Ordnance Survey benchmark: OSBM G1692

NOTE : Cette image est un panorama constitué de plusieurs clichés fusionnés en utilisant un logiciel.
En conséquence, cette image a forcément subi une certaine forme de retouche numérique. Il peut s’agir de fondu, floutage, duplication et ajustements de couleurs et de perspective. Cette image peut donc être légèrement distincte de la réalité aux endroits de raccord. Cette retouche est souvent nécessaire en raison de déformation de parallaxe ou de perspective.

For photographers
First, you should be aware that a good photo is taken by the photographer themselves. The focus is therefore on composition and creativity. At least when you are starting out, it is advisable to follow the rules of composition. The camera and lens are tools for creating the photo. Technically speaking, a photo is only as good as the tools allow it to be.
If creativity and high quality are important to you, you should say goodbye to fully automatic mode. However, individual automatic functions can be useful. It is better to make some camera settings consciously, so it is also important to use them selectively.
There are only a few basic parameters that affect a photo. These are aperture, exposure time and ISO value. The aperture determines the depth of field in the image. The wider the aperture is open, the less sharp the image will be, and vice versa. However, the aperture should only be closed as far as is absolutely necessary. The exposure time should be short enough to prevent the photo from being blurred. The shorter it is, the more likely it is that movement will be frozen. The ISO value determines how sensitive a sensor is to light. The higher it is, the more sensitive it becomes. (More precisely, the light signal is amplified.) However, this has a disadvantage, because as the ISO value increases, so does the noise.
You should be able to focus correctly on the camera. You don’t necessarily have to focus manually, but you should be able to select the appropriate focus fields yourself. Furthermore, the significance of the focal length and its effect on the photo should be actively selected. For example, a longer focal length results in a compression effect, which has its own image effect. Even when using a zoom lens, it can’t hurt to take a few steps forward or backward.
Of course, this is only a very brief overview. There are other influencing factors and parameters, but these cannot be conveyed in the brevity of this text.Colors, light, perspective, and facial expressions influence our mood: warm colors have a stimulating effect, cool colors a calming one. A familiar face or a specific place can immediately trigger memories and associated emotions.
At the same time, the way we take photos reflects our inner world. The choice of subject and image composition can reveal unconscious themes. This is used in psychotherapy: photos help to express feelings, activate memories, and reflect self-image. Images thus become a bridge between emotion and language.
Maybe you’re waiting for the “perfect” subject. For better light. For more time. But creativity doesn’t start with perfect conditions — it starts with curiosity. With the courage to look. With the decision to get started today.
The light in the morning tells different stories than the light in the evening. Shadows paint patterns on walls. Raindrops transform into tiny universes when viewed in macro. An ordinary street becomes a stage when you observe it patiently.
You don’t need the most expensive equipment. You need your eye. Ask yourself:
- What do I overlook every day?
- How does this moment feel?
- What happens when I get closer — or further away?
Allow yourself to experiment. Play with perspectives. Crouch down. Take pictures against the light. Deliberately crop something out. Break the rules — after you know them. Not every picture has to be perfect. Every picture can be a step.
Creativity comes from doing. So get going. Capture what moves you. Show your view of the world — because no one else sees it the way you do.
Your camera is not a tool for perfection.It is a tool for expression.
