Digital Infrared Photography Pictures Made Easy

Digital infrared photography is a fairly basic photographic technique that yields amazing images. There is a spectrum of light that can not be seen with the human eye, but it can be seen and captured through the lens of your digital camera.

Images captured with this technique have a surreal dreamy look. A picture of a green leafy tree against a bright blue sky taken with digital infrared photography becomes a picture of a brilliant white tree against a dark foreboding backdrop of sky.

This happens because visible light is ignored and only infrared light (light from the spectrum we can not see with the naked eye) is captured. The resulting compositions are stunning. However, the technique is not difficult.

Digital Infrared Photography Equipment

Infrared pictures can be really unique. Here is a resource to learn more about the technique and see samples of what can be done with inferred photography.
A digital photography course is a great way to learn this technique. There are even free digital photo classes offered online [http://www.mydigitalphotoclasses.com/digital-photo-classes.html].

Modern digital cameras differ in their ability to capture infrared light. To test your camera's infrared capabilities, point your television remote control at your digital cameras lens from 6 inches away and press a button on the remote. If you see a light in your camera's LCD coming from your remote, you're in luck. Your camera is capable of digital infrared photography. If you saw no light being emitted from the remote, your camera probably has an internal infrared filter installed by the manufacturer to preserve the camera's ability to focus on images in the normal light spectrum.

Now that you've tested your camera, you need only two additional pieces of equipment: a filter and a tripod. The purpose of the filter is to "filter" out visible light and only let infrared light through. Filters are fairly inexpensive (approximately $ 20). The Hoya R72 filter is one of the more popular filters and can be obtained from your local camera store. If your camera has a thread adapter (most digital cameras do not), you'll also need to purchase an adapter. If your camera does not have a thread adapter, you'll have to get creative to attach the filter. With gelatin filters, it's as simple as cutting the filter to size and taping it to your lens. Your local photography store should be able to help here, too. While you're at the camera store, pickup a tripod also. These are needed due to the increased aperture and reduced shutter speed required for infrared photography.

Shooting Techniques

Once you've got your camera outfitted with an infrared filter, you're ready to go out and shoot. Landscapes with green leafy foliage and a bright sky make the best subjects when starting out. Portraits of people in sunlight also make interesting compositions. Every camera is different so you'll want to experiment with various settings and their effect. Some cameras are capable of taking good digital infrared photography in "automatic" mode, so try that first. However, if "automatic" mode does not yield good results, the following is a list of manual settings to use as a starting point:

  • Flash Off
  • Black & White Mode On
  • Film Speed: ISO 400 (or the highest available)
  • Shutter Speed: 1/15 of a second (slower is better)

Digital infrared photography opens up a whole new world to photographers. With just a few relatively cheap pieces of equipment, you can create stunning compositions from the world of the invisible light spectrum. This article just scratches the surface of what you can do with digital infrared photography . There is so much more that can be done within this area of ​​photography and there is a whole array of other basic photography techniques that yield amazing results. The best way to learn how to take full advantage of your digital camera or expand your photographic skills is by taking a digital photo class. They are a lot of fun and with just a little instruction you can learn how to take amazing pictures.

How Rigs for Water Wells Operate

To find new artesian wells, technology absolutely has to help us. With technical and mechanical innovations together with hydraulic engineering it has been possible to build rigs that are more and more efficient and are able to go to very important depths while drilling even more resistant layers of rocks. An artesian well is an under earth rich reserve of pluvial water: it is about natural resources that are hidden in the earth’s ground, the precious water supply of an area can be more or less extensive. The drilled hole of an artesian well lets water spontaneously come up to surface, without the use of submersible pumps. To find this underground water it is thought necessary to use a rig that is appropriate to our aim. Modern rigs, designed and realized by companies from this sector, are able to drill into the layers of the earth for many hundreds of meters. We are talking about mobile rigs, i.e. mounted on trucks or trailer either big or small depending upon the dimensions and weight of the equipment; this will let us move the rig inside the working yard without too many problems.

The choice of the correct rig to drill water wells is a choice of fundamental importance. Depending upon the well’s depth the rig will need to be more or less powerful. The best way to find the most appropriate rig is to trust and search the internet. You just need to open the browser on Google or Bing pages and type “drilling rigs for sale”. Over the world there are many companies that are operating in the sector of designing and realizing rigs. There are companies that are specialized in building rigs dedicated to water research. Others do have rigs to drill inside mines. Others specialize in oil exploration in the deepest layers of the earth from either marine platforms or on the mainland. There are also bigger companies that offer a wider range of drilling equipment. It is not always necessary to buy a new drilling rig. Most companies suggest and offer to their clients the option to hire and sell used rigs which can be recommended for small works when it’s not necessary to use equipment for a long period.

It is possible to find rigs that are fit for any purpose; it is though important to know that not all rigs are equal. For instance there are mechanical rigs which normally operate by diesel engines. There are electrical drilling rigs powered by energy sources generated in the work place, often they have engines with internal combustion. There are hydraulic drilling rigs that are using hydraulic oil flow operated by diesel engine. The system includes one gear box on which are connected different hydraulic pumps. Moreover modern rigs do differentiate themselves for their drilling method; these rigs can work a percussion system or rotary drilling method. The first ones impact the ground vertically drilling a large diameter hole in the ground; these rigs are mostly used when searching for water at low depths, but with very large diameter. Other types of drilling rigs instead, operate by rotating movement with a specific tool, normally called a bit.

Diamond Earrings and Other Fine Jewelry

Diamond rings are the most common form of diamond jewelry, but diamond earrings, bracelets and necklaces are also quite popular. In fact, diamond jewelry has been around since the days of the Roman Empire, although it took almost 1500 years before diamond jewelers had figured out how to cut diamonds into attractive shapes that displayed their "fire," or shine and brilliance. Diamond earrings are but one way that people adorn themselves with this mystical, precious gem.

A Fascinating History

Chances are that the first diamond jewelry was from India. The tremendous geologic forces required to form diamonds exists mainly in regions of the world where one tectonic plate slams into another; the Himalayas, where the Indian subcontinent plows into Central Asia, is one such place. Loose diamonds from deep underneath these mountains have been known to appear in the rivers that flow south and westward from the Himalayas: the Ganges, the Brahmaputra and the Irriwaddy have all been sources of these rough, octagonal crystals.

Before diamond jewelers had learned the art of precision cutting, diamond earrings were not particularly beautiful; rough and dull-looking, they were nonetheless prized for their hardness.

One early example of diamond jewelry in the West was actually a crown made for a Hungarian princess well over 1000 years ago. One of the first diamond wedding ring was the one given to Marie of Burgundy on the occasion of her wedding to Archduke Maximilian I of Austria in 1477. It was not until over fifty years later however during the reign of Henry VIII of England that diamond cutting had reached a level that was suitable for jewelry such as diamond earrings.

Dull and Lifeless

If you had been buying diamonds back then, you'd have been disappointed; those early cuts did not show the kind of brilliance that we see in fine diamond jewelry today. It was not until the 1800s that art of diamond cutting had reached a level of refinement that allowed the gem's real beauty to shine through the way it does in contemporary diamond jewelry.

Fiery and Brilliant

Today, there are many different cuts to choose from when buying diamonds . Round cuts and square cuts both have characteristics in their favor, but a reliably new cut, called the "princess," has been gaining in popularity over the past thirty years or so. This particular cut combines the best features of round and square cuts, and causes the least wastage of all cutting methods – so the gem retains much more of its original weight. All three cuts however will make for highly attractive and valuable diamond earrings .
