Touched By A Tablet - Choosing The Right Graphics Tablet For You

Touched By A Tablet - Choosing The Right Graphics Tablet For You

By: Annie Goss

There you are: you have finally decided to purchase a graphics tablet. Whatever your reasons may be for purchasing one, you are now faced with a very major decision: amongst all the numerous graphics tablets out there, which one would best suit your needs and your budget ?

Wacom is without any doubt, a genius when it comes to graphics tablet (also known as pen tablet) technology and is continually improving their products. Due to these frequent upgrades, this article will only touch the following Wacom models: Bamboo, Bamboo Fun (a successor and an improved model over the Graphire series), Intuos3 (the 3rd generation of Intuos) and Cintiq.

The basics

All Wacom graphics tablets are easy to install and use, thanks to Wacom?s Plug & Play technology. Every Wacom tablet is compatible with Macintosh and Windows, supports widescreen format, offers application and tool settings, provides a comfortable design and comes equipped with a detachable USB cable, and a programmable, cordless and battery free ergonomic pen. Therefore, your decision will be based on the main differences between these major models. Those include: pressure sensitivity, resolution and size.

? Pressure sensitivity of the pen tip and its eraser( when present) is measured in levels: 512 levels for the Bamboo line and 1024 levels, the highest thus far, for the Intuos3 and Cintiq models.

? Resolution, measured in lines per square inch, is marked at 2,540 for the Bamboo series and 5,080 for the Intuos3 and Cintiq models. Based on these two differences alone, if one needs or desires more precision and sharper results, the Intuos3 or the Cintiq are by far the better choices.

? Size relates to the active area of the graphics tablet, which is the drawing/writing area and not the actual size of the tablet. If space is really a tight issue, make sure you take into consideration the actual dimensions of the graphics tablet. Since the active area of a tablet matches your computer screen no matter what size it is, don?t let a smaller sized Wacom tablet fool you: the smaller sizes offer just as many features as the larger ones. Size becomes a concern when considering desk space, laptop use, portability, and user preferances. Bamboo, Bamboo Fun Small and Medium, Intuos3 4×6 and 6×8 are all wonderful options for small working environments.

Bringing pen to tablet: beginners

Let?s start by comparing the three Bamboo models.

? Bamboo standard (4×6 approx.) with its sleek black piano finish, is a wonderful improvement over the past Wacom models. It is perfect for any office, be it at home or at work and a perfect travelling companion. Specified mostly for office work rather than artistic tasks, it performs very well by working with your computer?s existing software for marking up documents, jotting down notes and writing your signature. So if you do not need any extra art related software, and the budget is as tight as your desk space, this is the perfect graphics tablet for you.

(Bamboo standard is the only Wacom tablet, of the newer models, which does not come with a matching mouse, or any software. The accompanying Bamboo pen does not have an eraser which could prove to be inconvenient.)

? Bamboo Fun (Small) (4×6 approx.) is terrific for children and beginners with creative minds. With four colors to choose from, (Blue, White, Black and Silver) you can personalize any office, home or at work, with your preferred color. However, despite the great Wacom quality and advantages, the active area might prove to be too small for elaborate projects.

? Bamboo Fun (Medium) (5×9 approx.) which also comes in the same 4 different colors as the Small version, is ideal for beginners and excellent for young students, digital photographers and more creative users. The new possibilities range from personalizing your work with your signature or other creations to touching-up photos.

Bringing pen to tablet: intermediate

The Intuos3 line, in its cool charcoal gray color and with an extra year warranty, replaces the Bamboo?s Touch Ring (at the top of the tablet) with a Touch Strip (at the side of the tablet for scrolling). The position of the ExpressKeys (for shortcuts) has also changed from the top (on the Bamboo) to the side (on the Intuos3). The Intuos3 also adds tilt control to the mix, an added bonus for any serious user. It even offers more pen tips for different writing and drawing results with the one accompanying cushioned Grip Pen which provides extra comfort and reduces tension. Extra accessories are available for the Intuos3 such as an array of different pen types ranging from the classic pen for a more natural, day-to-day work and feel to the sophisticated airbrush for unbelievably realistic paintings and other art designs. The whole Intuos3 series is specially designed for wide screens and multiple monitor work stations. If you are a serious graphic artist or you spend long hours using artistic software, an Intuos3 is certainly a worthwhile investment, and most graphics professionals would call it an essential tool. That said, there are still 6 different sizes to chose from !

? Intuos3 4×6 is easily portable with more features than the Bamboo series and perfect for small desk spaces yet affordable. However, this graphics tablet is not recommended for left-handed users because the single set of ExpressKeys and Touch Strip is on the left side of the drawing tablet. (All the other Intuos3 sizes have dual ExpressKeys and a Touch Strip on both the left and right sides of the tablet.)

? Intuos3 6×8 benefits more professional work yet is still an excellent size for cramped spaces and is a perfect travelling companion for the laptop and ideal for serious students on the go.

? Intuos3 6×11 targets the CAD users, and technical illustrators which may desire a larger surface area and artists who are used to drawing or painting with large sweeping motions. It is also optimized for work in single screen or for multiple monitor work stations and is ideal for editing HDTV videos. Remember, the larger your tablet surface, the more you will need to move your arms which may be viewed as a disadvantage to some users.

? Intuos3 9×12 greatly assists professional photo-retouching artists, illustrators and industrial designers with challenging endeavours, allowing for wider sweeping strokes.

? Intuos3 12×12, the only square tablet, caters to professionals with elaborate artistic ideas and highly detailed expectations like professional technicians and designers in any industry including automobile, textile and fashion.

? Intuos3 12×19 targets sophisticated and high-performance work involving precision and accurate results like professional digital imagery, audio-visual technicians, graphic artists, and architects. It offers optimal use of wide screen and double monitors and is excellent for creating HDTV videos.

Bringing pen to screen: intermediate and professional

Cintiq is the combination of the Intuos3 technology with an LCD monitor. The result: a state of the art monitor that allows you to write or draw directly on the screen with unparalleled accuracy! The fact that it is detachable and totally adjustable to any angle and for any purpose (on your desk or on your knees) makes it the holy grail of the Wacom graphics tablets and obviously, the most expensive. The Cintiq series (which comes with an Intuos3 Grip Pen for optimal comfort and fatigue prevention) will greatly improve workflow and efficiency while providing spectacular, detailed results in any professional field ranging from industrial designers, audio-editors and animators to doctors, educators and story-board creators requiring faster visual effects.

Yet again, there are 3 Cintiq?s to choose from. Size is measured diagonally, from the smaller 12.1?, and mid size 20.1? to the large 21.3?. The native resolution and the total number of pixels (1.0, 1.8 and 1.9 million pixels respectively) are what set them apart the most.

? Cintiq 12WX (1280×800 native resolution) is very light (4.4lbs) and portable thanks to an extra cable and a convertor box to keep it small and lightweight. It?s half the price of the other Cintiq models. However, due to its small size, you may want to add this to a multi-monitor set-up. If you are a very serious artist or technical designer, it is recommended that you save for the next model up.

? Cintiq 20WSX (1680×1050 native res.) is every professional?s dream. This 20 lb unit is the preferred choice by many due to its price and size. Less costly than its larger brother, it basically offers the same features.

? Cintiq 21UX (1600×1200 native res.) is the top of the line for pixel perfect results. Weighing in at 22.4 lbs, it?s the only Cintiq with an aspect ratio of 4:3 (standard resolution). All the others have 16:10. See it in action by going to YouTube.com and searching for Cintiq ? it is absolutely incredible !

When trying to choose between all of these great Wacom contenders, wallet and desk size will always be an issue. Everyday users for home and basic office duties will delight in Bamboo, Bamboo Fun and Intuos3 4×6. Professionals at home or at the office in all fields will require and thoroughly enjoy Intuos3 6×8 and up. (Academic specials for students and schools do exist for the Bamboo and the Intuos3.) Serious illustrators, educators, technical designers and artists demanding elaborate detail and high pixel perfection will absolutely love the freedom, comfort, efficiency and convenience of drawing directly on the screen ? and for many users - that is priceless.

What Exactly Are Radar Detectors?

What Exactly Are Radar Detectors?

By: Alex Baumm

Do you know what radar detectors are? You have seen them used in your favorite movies. You have heard them used in sci-fi and spy television series and probably you have seen them in your favorite action sequels. But have you heard of radar detectors used in determining car speed?

The year was 1887 when Heinrich Hertz started studying radio waves. Hertz’s experiments became the corner stones of radar technology as we know it today.

Through the years, we have witnessed the application of radar technology in a number of important fields. We have seen radar technology applied in many important parts of world history like that of World War I and World War II. Radar technology has saved so many lives ever since it first took breath.

Radar detectors are used in so many ways nowadays. They are used in military and research facilities and they are now used in apprehending drivers who are over speeding which is violation one of the important traffic regulations in all countries all over the world.

Monitoring car speed especially in superhighways and express highways or even town roads and streets is one great thing that traffic enforcers do because that lessens occurrence of accidents which are car-related.

So, how do radar detectors work?

Radar detectors or radar guns are forms of radio transmitter and receiver rolled into one. Radar detectors oscillate electrical energy into varying levels which generates electromagnetic energy.

This electromagnetic energy travels through the atmosphere in the form of electromagnetic waves. This electromagnetic wave is increased exponentially through the use of a especial kind of amplifier.

The receiver is merely a transmitter but is reverse form of it. This time it collects electromagnetic waves and transforms them into electrical current.

Radar detectors are used to monitor the distance of objects in relation to a reference point.

The reference point is obviously the radar detector. The electromagnetic waves are sent through the air and reflected back to the radar gun which then measures the distance of the object at a given time. This is then calculated by the machine to determine speed of the object.This manner of using radar detectors maximizes what is known as Doppler shift.

Radar detectors are must-haves for today’s law enforcers to catch traffic violators. They are great things that Science made for the benefit of the people. But as of now, this technology is not yet used by many countries which make it difficult to accurately pinpoint car speed violators.

Radar detectors are available from many shops and companies. You can gain access of these companies online or by other means.

Radar technology is a proof that we can benefit so much from the efforts of our scientists and other people who engineered and perfected the radar technology by investing so much effort, money and time to achieve the goal of developing a true life-saving device.
