Digital cameras of a high-resolution are no longer a luxury item; five mega pixels are the norm. The cameras are becoming ever more sophisticated and yet the prices have plummeted. Comparison sites will search for the best prices and a keyword search of eBay will list thousands of offers. Internet review sites provide all the technical information you want to make an informed choice. It’s that easy to find the right digital camera at the right price.
So what specification do you need? One mega pixel is one million color dots per picture. Ideally you should buy a camera with four mega pixels or more. Actually five mega pixels is the norm these days and cameras are now being made with eight mega pixels. More mega pixels mean larger pictures without sacrificing quality.
Digital cameras come with built in memory capacity but it's never enough. No problem! The flash memory card has been invented. It not only increases the amount of pictures you can take and store but makes transfer to a computer child's play. The amount of flash memory you need depends on your application. Test it out, a 256Mb or 512Mb may be enough and memory prices are so low now it won't break the bank to buy a spare.
Digital cameras have a zoom facility and you should consider the zoom factor carefully. There is optical zoom and digital zoom. Optical zoom uses the lens to enlarge the image. The optical zoom factor is the most important. Digital zoom on the other hand enlarges pixels digitally, no surprise there! This is a useful feature but remember you can always enlarge the image on your computer so it's not so important as optical zoom.
The advantages of digital photography were first recognized by real estate agents and motor traders. These sectors have always recognized the benefit of adding photographs to their ads. Instant digital photography was an answer to their dreams. But as the mega pixels increased so did the fans.
Anyone earn extra cash with a digital camera. Listings on auction sites such as eBay always get better results when one or more photographs of the product are included. Some online classified sites allow photographs also.
The use of pictures in advertising is just one of the many examples where you can earn extra money.
Whether you use a digital camera for fun or profit carefully consider what is required to get optimal results for your needs. Maybe the camera you already have is adequate. Maybe that latest hot-off-the-production line model is actually over specified for you. Hopefully this article has given you a few ideas and the facts to make an informed decision.
