The Differences Between A Digital Camera And A Traditional Camera – Digital Camera Inner Workings

Digital Cameras use lenses and a shutter to capture light inside the body of the camera just like traditional film cameras, but that is where the similarity ends.

Instead of using film to capture an image as the traditional cameras do, the digital camera captures the image using an image sensor.

These sensors are completely electronic in their operation. They have various internal electronic devices to measure light intensity and a host of other duties.

The complexity of the image sensor determines its rating, measured in MegaPixels. The higher the number of megapixels that a digital camera offers, the greater the clarity and quality of the resulting picture. Also the higher the megapixel rating of the digital camera, the higher the cost of the camera.

Digital cameras function by converting light into an electrical signal that is, in turn, converted into binary (1′s and 0′s) so they can be processed through the digital camera’s on-board computer. After the binary numbers are processed they are stored on the digital memory card or floppy disk.

The digital camera processes the light in such a way that the light is converted into the primary colors of Red, Green and Blue using internal filters. The photographs must be further refined by computer processing to produce the full color photograph. This process is called Demosaicing.

Many cameras offer photo sharpening to make the digital photographs clearer; usually, there are controls on the digital camera to adjust brightness, contrast, and color saturation.

After all this is done — inside the digital camera — the last step is to compress the image and then store it on the memory card.

To load images from a digital camera onto a computer and give you the ability to process the digital picture manually, requires a digital camera that offers this cability. If you would like this feature you should ask if the camera you are considering includes it before making your purchase.

Work From Home, Online Employment

Working from home on the internet provides users with the convenience and job security they require. A home job that is done on the internet can be what you need to get you started on a career path that will lead to job satisfaction and success in every sense of the word. Building a successful online business takes time, hard work and some investment capital, though more time investment may remove the need for capital investment. The good thing about online businesses is that anybody can develop one and be a success in it without any qualification or heavy capital investment. An online job should be taken seriously if meaningful progress is to be made in good time. Online jobs are numerous and can be grouped into three categories which include; skilled, semi-skilled and unskilled jobs.

Skilled jobs: basically, a skilled job is one that requires a certain level of skill and certification to accomplish. Skilled jobs are for individuals who have acquired a high level of expertise in order to be able to carry out the duties required of such tasking jobs. These jobs may only be given to those who have the qualifications and the much needed experience that such jobs require for effective and satisfactory results to be obtained. Performance for certain skilled jobs online is at a very high level based on the job description. Certifications for many skilled jobs are acquired offline by attending educational institutions. Some skilled jobs can also be learned and certification given online after a mandatory learning process and examination has been passed. Examples of some skilled job services that are provided for online customers include; web designing; website security; professional services such as stock brokering and ecommerce services; program writing and networking among others.

Semi-skilled jobs: these are jobs that may or may not require certification for one to be able to accomplish. Semi-skilled service providers may be required to have a certain level of qualification in some quarters but may not need to have any qualification in others. Most semi-skilled jobs can be learned and certification provided for those who have passed online. Examples of semi-skilled jobs online include search engine optimization, copywriting and secretarial skills among others.

Unskilled jobs: these are job descriptions that can be done by anyone without any prior certification. Most online jobs are in the unskilled category and you do not need any qualifications to become a service provider. The vast majority of service providers in the unskilled category learn these jobs and become experts by continuously providing their services to customers. This is the main reason why the internet is seen as a very good avenue to develop a viable business. Unskilled jobs require little or no income to start practicing and in a very short period, depending on your work rate, you can earn considerable amounts of money from them. Almost every internet business has a link with an unskilled job description which makes it possible for everyone to benefit from providing any kind of service on the internet. Examples of unskilled jobs that have their roots on the internet include article writing, link building, blogging, lead generation and social networking among others.

The internet is a user friendly environment that helps a lot of people all over the world develop certain basic skills and earn a substantial living. Whether your skilled, semi- skilled or unskilled, there is a place for you in the online business world.

Which Costa Rican Car Company Is Best?

Renting a Car in Costa Rica? Which company should you choose?

There are so many rent-a-car companies to choose from in Costa Rica – from the large international firms to the smaller national agencies. Reviews on the internet invariably either damn or sing the praises of each company to the extent of being almost useless. So how do you choose the best place to hire a car for your trip?

Many tourists that rent vehicles in Costa Rica complain that they have been ripped off when they realize the extra cost of insurance they are obliged to pay or that they have been charged a dollar rate that reflected the currency rate and not the quoted rate. Understanding the insurance laws and charges that bind the Costa Rican car rental companies may help you to ask the right questions when you are reserving your vehicle and avoid a nasty shock upon arrival. If a company is not upfront about its additional costs; you may wish to consider whether it is a company that you choose to take your business to.

I have worked within the tourism industry in Costa Rica for the last six years and have lived here since 2000. I am familiar with the feelings that many visitors to the country experience when dealing with rent-a-car companies. These can range from delight to discomfort to outright fury; sometimes due to the inefficiency, or even dishonesty of the rental agency, but also due to the renter’s lack of understanding of the legally binding restrictions within which Costa Rican car rental firms must work. I hope that while this article won’t guarantee you trouble-free vehicle rental; it might make you a more knowledgeable customer.

Insurance needs, additional costs in rental and surcharges are considered in more detail below:

Insurance:

Basic insurance is mandatory. Costa Rican law is very clear on this and your rental car company cannot allow you to leave with their car without having agreed to pay it. Expect to pay somewhere between $9 and $20 per day on top of your car rental rate. An honest, car rental agency will make this very clear in their pricing. If it is not clear whether the insurance is included in the rental cost; ask for clarification and be aware of other potentially unstated costs.

Check whether your insurance policy covers you to drive in Costa Rica. Some policies include Collision Damage Waivers and will cover Central America. If you are covered, bring proof (in writing) for your vehicle rental company. If not, consider whether you would be safer to pay the extra cost of this additional coverage. This part is not mandatory.

Zero liability is offered by rent-a-car companies. You may wish to consider whether you would feel more at ease knowing that you would not be liable for any costs should something occur while you are renting their vehicle. You are not obliged to buy this supplemental insurance.

Additional Fees:

Many car rental companies will charge additional fees for a child/baby seat, an additional driver, luggage racks or cooler. You can expect to pay up to $8 daily for each of these extras. Although by shopping around, you can find companies that will offer some or all for a lower price, or even free.

With Costa Rican roads being notoriously poorly signposted and the whole country operating on an address system based on landmarks rather than road names or numbers, a GPS is essential for many car renters. You will usually pay between $8 and $15 a day for this service. It is fairly common practice to allow renters to use one of their cell phones for the duration, but if you wish to use it for your own calls; you’ll obviously be charged.

Surcharges:

Some rental car companies incorporate taxes and additional fees into their rental cost; others don’t. Make sure you know what you will be charged for on top of your rental fee. Airport fees can be charged at 13% of your rental cost which is a sizable fee to pay in addition to an agreed rental charge. You may also be charged a license plate charge, environmental fee and/or any other charge that the rental car company has to meet (or pocket).

Prices for the rental will be given in US dollars, but as the local currency is colones, you should understand that exchange rates change daily and what you are charged on your credit card on the day of payment may vary slightly from what you were quoted.

Criteria for Rating Car Rental Companies:

For this article, three (3) main points were considered for each company:

1) Value: Is the rental rate competitive?

2) Efficiency: How fast do they respond to the needs of the client?

3) Transparency: How clear is the information provided by the company?

You may have your own criteria, but based on complaints from previous customers on community websites like Trip Advisor, Lonely Planet, etc., the requirements of those clients seemed mainly based around these three basic areas.

Finalizing the Three Criteria:

Economy, at first, appear to be the cheapest company to rent from, but unfortunately this is due to their failure to declare all costs incurred by the renter, rather than a genuine, good deal. For real value, Dollar, Vamos, Wild Rider and Tricolor come out on top for competitive pricing for the basic rental fee, plus mandatory insurance. Vamos is noticed for being the only firm that does not charge for extras such as a child seat or surcharges. Adobe and Service have low cost extras, whereas Hertz has the most expensive rates for extras. Wild Rider does not charge for an additional driver.

Only Economy failed to respond to email inquiry. All other companies responded quickly and with clear answers to inquiries. Wild Rider, as the smallest firm, cannot offer nationwide service, but reviews suggest that they have met customer needs to date. All other companies can offer services from offices in locations outside of the capital city — increasing their ability to serve clients effectively.

Adobe, Wild Rider, Vamos and Service have websites that clearly show rental prices and insurance. Economy and Hertz somehow seems to be deliberately misleading on their websites. The other companies’ websites provide the required information – even if it can take some time in hunting it down.

Conclusion:

This brief survey would suggest that Vamos, Service, Tricolor and Wild Rider would be the best companies to begin your rental research, whereas Economy would be best to avoid.

Now you know as much as I do! The information here is supposed to be your starting point and not the end point. Hopefully, you will know the right questions to ask when you’re looking for a rental vehicle to ensure that your dream vacation begins smoothly without any nasty shocks, like hefty extra charges when you land. Enjoy the drive!
