Are you looking for an image projecting solution for your home or business? Digital DLP projectors employ an image-screening method that is rapidly gaining popularity and is becoming renowned for its quality and reliability.

Looking to create the ultimate home entertainment system? Invest in a digital DLP projector to screen all your movies at home, in state-of-the-art surroundings.

Regularly give presentations, or running a business or organisation that requires the frequent use of high quality projection equipment for conference or training events? Digital DLP projectors are lightweight and operate at low noise levels and are currently placed at the very forefront of image projecting technology.

Digital DLP projectors use a relatively new image projection technique, known as Digital Light Processing (DLP) that has been in existence for about 20 years.

The new image projection technique was invented in 1987 by a technical specialist called Dr. Larry Hornbeck, who was then working for Texas Instruments.

DLP is another way of projecting digital images onto a screen and, since the invention of the technique in 1987, a great deal of work has gone into preparing the process for release into the commercial market, where it is now beginning to compete against other 21st century image display techniques, like LCD, plasma screens and high definition television.

DLP works by projecting an image through a complex matrix of a large number of tiny mirrors. The number of mirrors that your particular digital light projector contains will dictate the resolution quality of the image that is projected.

As DLP technology has improved, smaller, mass-market digital light projectors are becoming available for use in the office or home. These high-quality image projection devices make excellent additions to a home entertainment system and are handy tools for presentations and corporate screenings, as well as being a great additional piece of equipment for any educational establishment.

DLP technology works as both front and rear-projected, so digital light projectors are available as stand-alone units and also as box units that are fitted with a rear projector and include a screen within the box ‘ making it one handy image-screening unit.

The advantages of a digital light projector are manifold, with the best advantage considered to be its superior image projection quality, producing images on even the largest screens of a quality and clarity that has never been seen before.

Digital light projectors produce shake-free images and their light source is replaceable, which gives them a longer product life than other image screening options available on the market.

So, how can you benefit from this rapidly-advancing new technology and install a digital light projector in your home, office or educational establishment? The Nobo range of digital light projectors scores highly for image resolution quality and contrast and offers exceptional brightness. The Nobo range is easy to use, lightweight and portable and has been designed with entry-level operators in mind.



Digital Prints Are The Future For Photography

The digital revolution in photography has led to a huge increase in the popularity of photography as a hobby. From low resolution automatic cameras to high end Single Lens Reflex (SLR) cameras, the new lease of life that digital technology has bought to the industry is having a profound affect on photographic aesthetics. Once the realm of photographic professionals and artists, successful photography required the understanding of apertures, F stops, Lighting and framing. This started to change with the introduction of the automatic camera.

Automatic cameras allowed the general public, with no photographic training, to take pictures at the click of a button. This accessibility increased the popularity of photography as a hobby and this is the first point that the aesthetics began to change dramatically. The quality of the pictures was in no way comparable to that which could be achieved by a professional using an SLR camera, as the auto mated function was fairly basic. The quality of the photographic subject was also no threat to those working professionally. Blurred holiday snaps, badly framed portraits and out of focus close-ups were the realm of the amateur.

The new era of photographic equipment has revolutionised the aesthetics of this amateur photography by upping the anti in the technological department. Today’s automatic cameras have a multitude of auto focus points and utilizes technology so advanced that it had become nearly impossible to take a blurred photograph. Some of the latest cameras even anticipate the conditions with sensors, meaning that whether you are taking a shot on a snowy mountain or in a dark cave; in a moving vehicle or sitting in half lotus, each shot will turn out perfectly. And any shots that do turn out slightly fuzzy or skewed can be corrected afterwards in applications such as Photoshop, or by a digital print processing shop.

The possibility of producing such high quality images has led to many image sharing sites such as Flickr and Fotolog. These are online communities where professional s and amateurs can show off their talents and have their work rated too. It is possible to see through these sites the aesthetics of the medium changing, which has as much to do with the enhancements that digital ,technology offers whilst capturing an image as it does to the after affects that can be implemented afterwards.

Cropping, cutting and colour replacement can create images with a surreal and uncanny quality that is much more difficult to capture or manipulate on film. Consequently, the prints from the digital images differ from film prints. Film captures everything that is exposed on to it, whereas what is known as the dynamic range in digital photography means that extremes are not captured. This means that if an image has particularly shadowy or light drenched areas, a digital camera will not pick up the detail. This digital burnout produces solid black and white areas respectively.

The new wave of digital photos and digital print technology has led to a new aesthetic being seen in galleries around the world. Photographers and artists are using the new parameters as a tool to manipulate a subject, in particular, creating seamless montages of impossible images. Artists such as Jeff Wall and John Goto create images of the sublime and surreal that could not have been achieved without the digital revolution. Being able to capture images of varying scales and light so precisely and suture them together as one image by manipulating the tone and grading is a new skill for a new medium. Photographic technology will continue to evolve, producing photographs that go beyond the dark room, being rooted now with digital advancement.
