Nikon DSLR D60 Kit Digital Camera

Nikon DSLR D60 Kit Digital Camera is the latest model which is compact, bundled and functional having the VR lens on it. The 10 megapixel camera is one of the greatest of all attractions along with the APS-H Sensor. It is build along with the stabilized lens which is optically found and the best for the price concerned. The body of the camera is simply the perfect thing to have and it has all the features to make it the best in the new comer list.

It has the features specified in the DSLR which includes the fast burnt mode and also the RAW support completely. The quality of the image is simply remarkable and it suits the camera well and good. The color of the camera seems to be the best and the noise seems to be extra ordinary. One of the greatest of all advantages seems to be D-Lighting which seems to be the dynamic range booster.

The Nikon DSLR D60 Kit Digital Camera is simply the best for the beginner in photography as well as those who are into taking photos in the professional way. It has the latest VR lens which adds to the superiority. Another important related aspect is fast operation. The overall image quality is simply mesmerizing and it is the best for the concerned price. The body is simply sleek and can be handled pretty well.

There are just slight differences in the diffraction even though not in all the cases. The overall ranking of the camera states to be in the Very Good position. Using the camera is pretty easy and the buttons are very few and can be managed well in the best possible way. The rubber grooves works in the perfect way to prevent any kind of slippage.By John Axelberg http://www.electroniceasy.com

What is Blu Ray Disc

In February 2002, the leading optical storage companies formed the Blu-ray Disc Founders (BDF) and announced the initial specifications for Blu-ray Disc, a high-capacity CD/DVD-type optical disc format. By May 2002, the Blu-ray Disc (BD) specification 1.0 was released, and in April 2003, Sony released the BDZ-S77 for the Japanese market, the first commercially available BD recorder. In January 2006, the Blu-ray Disc Association also released a 2.0 specification for BD-RE discs. Blu-ray is a fully rewritable format that enables recording up to 25GB of data or up to 2 hours of high-definition video on a single-sided, single-layer 12cm diameter disc (which is the same as existing CDs and DVDs) using a 405nm blue-violet laser. Dual-layer BD recorders are also being developed and will record up to 50GB. Although backward compatibility with DVD and CD is not a requirement of the Blu-ray specification, it is a feature drive manufacturers can easily include. In fact, all the Blu-ray drives announced so far have full backward compatibility with DVD and CD formats.

One of the main application for higher-capacity optical storage is recording high-definition TV, which takes an incredible amount of storage. Current DVD recorders can't store enough data to handle high-definition video. Blu-ray, on the other hand, is designed to store up to 2 hours of high-definition video (or more than 13 hours of standard broadcast-quality TV) on a single-layer disc, or double that when dual-layer versions become available. As with DVD, Blu-ray uses the industry-standard MPEG-2 compression technology.

The Blu-ray Disc 1.0 specification includes the following formats:

• BD-ROM. Read-only for prerecorded content

• BD-R. Recordable for PC data storage

• BD-RW. Rewritable for PC data storage

As of January 2006, only the BD-RE format, which is a rewritable format for HDTV recording, had been revised. The current specification is BD-RE 2.0.

Standard CDs use a 780nm (infrared) laser combined with a 0.45 numerical aperture lens, whereas DVDs use a 650nm (red) laser combined with a 0.60 numerical aperture lens. Blu-ray uses a much shorter 405nm (blue-violet) laser with a 0.85 numerical aperture lens. Numerical aperture is a measurement of the light-gathering capability of a lens, as well as the focal length and relative magnification. The numerical aperture of a lens is derived by taking the sine of the maximum angle of light entering the lens. For example, the lens in a CD-ROM drive gathers light at up to a 26.7° angle, which results in a numerical aperture of SIN(26.7) = 0.45. By comparison, the lens in a DVD drive gathers light at up to a 36.9° angle, resulting in a numerical aperture of SIN(36.9) = 0.60. Blu-ray drives gather light at up to a 58.2° angle, resulting in a numerical aperture of SIN(58.2) = 0.85. Higher numerical apertures allow increasingly oblique (angled) rays of light to enter the lens and therefore produce a more highly resolved image.

The higher the aperture, the shorter the focal length and the greater the magnification. The lens in a CD-ROM drive magnifies roughly 20 times, whereas the lens in a DVD drive magnifies about 40 times. The Blu-ray lens magnifies about 60 times. This greater magnification is necessary because the distance between tracks on a Blu-ray disc is reduced to 0.32um, which is almost half of that of a regular DVD. Because of the very high densities involved, a simple cartridge is normally used to hold the disc, which prevents it from being impaired by dust, fingerprints, or scratches.

The most important features of a Blu-ray disc are summarized:

Blu-ray Disc Specifications

Specification	Value	Specification	Value
Capacity (single-layer)	23.3GB/25GB/27GB	Tracking pitch	0.32um
Capacity (dual-layer)	46.6GB/50GB/54GB	Shortest pit length	0.160/0.149/0.138um
Laser wavelength	405nm (blue-violet)	Recording density	16.8/18.0/19.5Gb/sq. in.
Lens numerical aperture	0.85	Data transfer rate	36Mbps
Cartridge dimensions	Approximately 129x131x7mm	Recording format	Phase change recording
Disc diameter	120mm	Tracking format	Groove recording
Disc thickness	1.2mm	Video format	MPEG2
Optical protection layer	0.1mm

Blu-ray, or perhaps some other blue-laser disc drive, will eventually become the replacement for today's DVD drives. For more information about Blu-ray, see the official licensing website at www.blu-raydisc.info/, as well as the unofficial Blue-ray site at www.blu-ray.com.

The Best Information on HDMI and DVI cables

With the advancement of so many electronical devices in the last decade, the need for proper cables has arose. There are countless cables out on the open market today designed for different features and different settings to enhance someone´s electronical experience.

With the advancement of so many electronical devices in the last decade, the need for proper cables has arose. There are countless cables out on the open market today designed for different features and different settings to enhance someone´s electronical experience. A couple of high demand cables include the HDMI cable and the DVI cable. These two cables are pretty similar but have a few key differences.

First lets talk about the DVI cable which stands for digital visual interface. It was released in 1999 primarily for carrying uncompressed digital video data to a display. Back then it was pretty much used for computer monitor, but now they are highly used for television sets. This part may get a bit confusing because there are three main connection types for DVI. They include the DVI-D which is digital only, the DVI-A which is analog only, and the DVI-I which is both digital and analog. So before selecting the best DVI cable for you, make sure you know which one you are getting.

The other cable I want to talk about is the HDMI which stands for high definition multimedia interface. This cable was introduced in 2002 and is an all digital´video interface capable of transmitting uncompressed streams of data. It is very similar to the DVI except the HDMI has the ability to also carry audio and video signals. The two cables do basically the same things, but the HDMI is a little better because it is a bit newer and can do a couple more features than the DVI cable.

Whatever cable you choose, make sure you get one that is compatible with whatever you are trying to connect it with. There are a number of cables that do different things and can affect your electronic device in different ways, so do as much research as possible before making your purchase.
