There are a wide range of options and features available for DSLR (digital single lens reflex) cameras and it can be confusing if you are buying this type of camera for the first time. This guide will help you decide which features are important to you and hopefully help you to choose your ideal DSLR camera.
A major factor in your decision is, of course, the price. DSLR cameras start at about $400 and can be as much as $8000 for a top of the range camera. A camera of between $400 to $1000 would probably be a good choose for a newcomer. Lenses tend to be expensive and can cost more than the camera body do make sure you take this into account when you make your budget.
There are four format sizes at the moment for 35mm DSLR cameras.
This format, with a sensor size of sensor size is 36mm x 24mm, is found on most higher end cameras and is the same size as that used in 35mm film cameras.
On a Canon camera this format has a 15mm x 22.5mm sensor and on a Nikon 15.6mm x 23.7mm. This format is used by most DSLR cameras except some higher end cameras and Olympus makes. Nikon call it a DX format.
This format is only found in a few cameras such as the Canon EOS 1D MkIII and has a 18.7mm x 28.7mm sensor.
This is a smaller format at 13.5mm x 18mm and is found on Olympus and Panasonic cameras. The aspect ratio is 3:4 unlike other cameras with an aspect ratio of 2:3.
All of the formats will give a good print out up to 11″ x 14″ which is the largest most amateur photographers will usually need. Most cameras below about $1000 dollars use the Four Thirds or APS-C format so the choice is usually dictated by the price rather than performance.
Image Stabilization Systems
Systems for image stabilisation vary between manufacturers. Some systems are mounted in the camera body others on the lens itself. Nikon and Canon use a lens based system and use gyros on the lens to sense movement and keep the optical groups stable. Gyros mounted on the camera body are used by Sony, Panasonic and Olympus in a stabilisation system called a sensor shift. The sensor shifts to compensate for any movement. Although both systems perform equally as well the lens mounted systems need to be included on every lens which adds to the cost. In addition not all lenses have the system included especially prime lenses under 200mm.
Size and Weight
Cheaper cameras tend to be smaller and lighter although, as no DSLR camera is going to fit into a pocket anyway, the size is not of primary important.
DSLR camera start at about 6 mega pixels (MP) and can be as much as 22 MP for a high end camera. The pixel count will dictate the size that a print can be blown up to and you need to decide how large you would like your prints before you decide on which model to buy. 240 pixels per inch will give a very good quality print so a 6 MP camera will be adequate for a high quality 8" x 10" print.
If you need larger prints a 10 MP camera will be capable of producing a good print at a size of 11″ x 14″. A top of the range camera with a pixel count of 22 MP will give excellent 11″ x 14″ prints.
ISO ranges between 100 and 1600 are found on most lower end cameras. Mid range cameras may have settings up to 6400 and a high end camera can reach as high as 25,500 and as low as 50. Most DSLR cameras will give pictures with low noise at ISO settings between 100 and 800 but the noise dramatically increases above this. The noise at the higher levels can vary considerably between models so, if possible, try to see images taken at higher setting with the cameras you are considering.
All digital images will have some noise which will be more noticeable at higher ISO settings. Noise comes from the electronics and sensor when the digital signal is produced from the analog signal. All DSLR cameras have noise filtering systems but this works less well above an ISO setting of about 800. Noise reduction softens the image so try to see images taken in low light if you will be using the higher range ISO settings.
Autofocus systems vary a great deal between manufacturers. All auto focus systems work well for static images but can vary a great deal for moving subjects, especially in low light. Check reviews of specific cameras for information on how well auto focus works for the model you are considering.
In this modern era, high tech devices that are very expensive like the computers can be replaced with cheaper ones. Such cheap computers mostly come in the form of used computers. Used computers can be found in abundance in the used computer warehouses in various places, even in the local area of the prospective buyer’s residence. However there is no guarantee of quality when buying a used computer.
The buyer has to take his own personal risk in doing so. But, if the buyer is ready to spend some money in upgrading the level of the used computer and also some time checking the quality of the used computer before purchase, it will save him from loss. Used computers can save a lot of money for the buyer when compared to buying a new computer. There are many who cannot afford to buy a new computer like the students who do not have any source of income but definitely require computers. For such people, used computers come as a boon.
Also, used computers need not always be second hand computers. They can also be recertified or refurbished computers. Refurbished or recertified computers are those, which are checked for any faults, if any corrected and sold with a warranty ensuring the working condition of the computer to be perfect. Hence, such computers are considered to be the safest form of buying a used computer. Refurbished computers can be bought from many of the online stores at very less prices. Quality computer manufacturers also sell such kind of recertified or refurbished computers. However, certain measures need to be taken while buying such kind of computers.
The prime aspect to be considered while purchasing a used or refurbished computer is to look for a good branded one. There are various companies who sell used computers or refurbished computers. The main reasons for opting for a branded one is that it comes with a warranty and also the buyer can be sure that the parts used are of good quality.
While buying used or refurbished computers related software documents, licenses and paperwork have to be got from the seller as this will avoid stolen computers being passed off as used computers to the buyer. If possible working for some time on the used computer will determine its efficiency. Most of the reputed dealers would allow the purchaser to use the computer for a shorter period to check the quality before purchase.
While checking for the efficiency of the used computer, it is good to check if the booting process is smooth, as most of the problems occur during booting and also to check all the sound drivers, video, graphics, monitor, mouse, keyboard etc. CD drives and hard disks also need to be checked. Another aspect is the support system offered for the used computer whether technical or non-technical, support staff capabilities and the number of support staff which determine the quality of service offered. If the purchaser is not satisfied, he can very well think of another choice.
It’s the second day of classes and I’m still stuck in my vacation moments. I’d still like to travel almost anywhere without thought of school projects left undone and without though of school obligations which leads to stress at some point.

It was a flat piece of written art on the board but it struck me and left the biggest question that might change me forever once I find the answer. “What is my ultimate mission?” Most people wait for signs and others just don’t care. But there are those who would do everything to find their mission. What’s the fuss all about? Why do we have to know and find out if we will still turn to ashes someday?

Highly targeted traffic is one of the most important entities in the internet universe. Any website owner or administrator recognizes the importance of driving traffic to a website. The success of any website does not rely entirely on the site itself. You may have a terrific idea for a website, offer an excellent product or service, or have an exceptionally designed site with superb content, but if you do not use the right strategies to advertise, your site would not attract the high traffic you need. Attracting targeted traffic is a task that should be taken seriously for any site to succeed or make a profit. Fortunately, there are internet-marketing tools that help the website marketer to drive traffic to his website. One of the most significant, and effective, of these tools is Google's Adwords. Adwords is one of Google's advertising services.
How does Google Adwords work?
Google is the largest search engine on the web receiving over 200 million queries each day through its various services. As Google is the most popular search engine today, webmasters are keen on having their websites achieve a higher ranking in the search engine results it provides. A high ranking can mean high traffic for that website. The search engine results page is also a great venue for advertisers to promote a product or service through ads and links. Consequently, Google launched its Adwords service, as a way for businesses to advertise products and services to a targeted audience. Google Adwords can guarantee instant traffic. In this service, Google displays relevant text based ads within its search engine results page termed as "Sponsored Links". Whenever a particular keyword is searched on, these relevant links appear in a separate section giving excellent exposure to the sites listed.
How do you use Google Adwords? First, you have to open an account with the Google Adwords Service. Then, you should indicate your target language and country. This is important because you would not want your products advertised in countries where your product or service cannot be sold. Afterwards, you should now create an ad group. This involves designing the ad, selecting keywords and determining maximum cost per click that you are willing to spend and defining bid amounts. The most important step in creating a successful Adwords campaign is selecting an effective title tag that will catch the attention of your target audience. The title tag, generally a short phrase, is the most important part of your Adwords campaign so make sure that it is attractive and catchy. You should describe the website clearly and accurately. The most effective advertising conveys a clear message to the target audience. With a clear message, you will be attracting qualified leads, which can eventually convert to sale. Thus, the importance of selecting the right keywords cannot be overemphasized.
There are keyword variations you can adapt to reach more prospects. Using these varieties, misspellings and derivatives can help increase the chance of your ads being served. Broad match is targeting keywords in a loosely defined manner. Here, the ads appear based on the keywords that have been queried by other users as opposed to exact match, which calls for the keyword to match the query exactly. Meanwhile, a keyword phrase set to phrase match will only appear when the exact phrase is searched on. A negative keyword is helpful in filtering unrelated pages.
After you have decided on what title tag to use in your ad, you must now define a budget in order to maximize exposure. Google Adwords recommend a daily budget for each campaign. However, you should determine a budget that is suitable and affordable. You should also determine the maximum cost per click. Google will offer a recommended cost per click, but you do not have to stick with this. Usually, a number one position is not ideal as it can also attract unwanted traffic and useless clicks. A number two position is more preferred as it can filter useless clicks and provide traffic with a higher conversion rate.
To conclude, Google Adwords is an excellent strategy and tool in giving your site maximum exposure. Nevertheless, Google Adwords should not be your sole advertising campaign. It will definitely help you find the all-important, highly targeted traffic you need.
WASHINGTON (AFP) - – Nearly half of US employers research the online profiles of job candidates on social networks such as Facebook, MySpace or LinkedIn, according to a new survey.
Forty-five percent of the employers surveyed for CareerBuilder.com, the largest US online job site, said they use social networking sites to check on job candidates, up from just 22 percent in a survey conducted last year.
Another 11 percent said they plan to start using social networking sites for screening.
"As social networking grows increasingly pervasive, more employers are utilizing these sites to screen potential employees," CareerBuilder said in a statement.
It said job seekers should "be mindful of the information they post online."
CareerBuilder said that of those who conduct online searches as background checks on job candidates, 29 percent use Facebook, 26 percent use LinkedIn and 21 percent use MySpace.
Eleven percent search blogs while seven percent follow candidates on micro-blogging service Twitter.
Thirty-five percent of those surveyed said they have found content on a social network that caused them not to hire a candidate, CareerBuilder said.
Examples included "provocative or inappropriate photographs or information" or content about drinking or using drugs.
Other reasons cited were badmouthing a previous employer, co-workers or clients, poor communication skills, making discriminatory comments, lying about qualifications or sharing confidential information from a previous employer.
Information found on social networking profiles was not always a negative factor in finding a job.
Eighteen percent of employers said they have found content on social networking sites that caused them to hire the candidate, CareerBuilder said.
Some profiles "provided a good feel for the candidates personality" or supported their professional qualifications while others demonstrated creativity or solid communication skills.
Rosemary Haefner, vice president of human resources at CareerBuilder, recommended that candidates "clean up digital dirt" before beginning a job search by removing photos, content and links which could hurt their chances.
The survey of 2,667 hiring managers and human resource professionals was conducted by Harris Interactive between May 22 and June 10. It has a sampling error of plus or minus 1.9 percentage points.
