In landscape photography, I find light is almost everything. A very ordinary view can suddenly become special, if the lighting changes – something that happens very often in England! This shot was taken in the early evening. I had stopped to watch this scene for a few moments, when suddenly the sunlight played the trick I’ve caught here. The whole event was over in seconds.It's kind to share!
…And, particularly, the light emitting diode, or LED, the marvel that is causing a revolution in all kinds of lighting. Homes, offices, shops, factories, car parks and many more situations are benefiting from the long life and amazing energy savings that this technology brings. Although commercial use of electro-luminescence is not new, The white LED as we know it has only been around for around twenty years – and was prohibitively expensive, to begin with.
The LED lamp in this picture is of the so-called ‘LED filament’ type, and at first glance resembles the first electric lamps made by Joseph Swan and Thomas Edison. The background looks black because the exposure has been optimised for clear portrayal of the LED filaments inside the outer bulb. In use, however, when inside a shade, it’s hard to tell the difference, in terms of light quality and colour appearance, between these lamps and traditional tungsten lamps – but they use around 10% of the energy!
Oh, and another key feature: at switch-on, full output from an LED lamp is virtually instant, in contrast with some types of fluorescent lamp, which leave you in the gloom for around a minute after starting, giving you plenty of opportunity to trip over some discarded toys, or whatever!
Mr Swan’s invention has done us well, for almost 140 years. Now, it’s time to move on.
On one evening last week, I caught sight of this tree. I’ve seen it many times before, but not lit like this. The endless changes in natural light can cause many fascinating effects that are just waiting to be noticed; it doesn’t happen to order – we just have to keep our eyes open!It's kind to share!
Here in Derbyshire, low, yet strong, afternoon sunlight has caught the profiles left by ancient ‘ridge and furrow’ farming. Amazingly, the pattern remains after centuries have passed.It's kind to share!
