A guide to Digital Cameras

Basically a digital camera is a device use to capture pictures without the use of film. The increased weight is because these cameras often use heavy batteries even though they have fewer moving parts. The storage used is similar to other computer based products so they are compatible with may other types of media we use to view images. This computer language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just captured.
These cameras still use lenses in much the same way that conventional cameras do. Instead of film the digital camera captures the light with the aid of a system which records the light rays digitally. A feature of the better quality versions is they have a sensor that converts light into electrical charges using a different system to their less expensive cousins. Some people believe the device used to capture an image in cheaper cameras the CMOS will eventually be the replacement for the better CCD but this is highly doubtful.
You may have noticed the price of some models has dropped, making them much more affordable to many people; the CMOS image capture device is the reason for this. Whilst both the CMOS and CCD systems both capture an image using millions of solar cells to make up the whole picture, they perform this in slightly different ways Information to help you choose a suitable model of camera is mention in this review. From the point of view on having good quality photos, search for a high megapixel version as it will be worth it for the image you will capture with it; if you are lucky you may find a model that is discounted because a new version is about to be introduced.
Where you have a choice, optical zooms on digital cameras are better than digital ones - always; perhaps you can remember how grainy and blurred images become when you used your camcorder’s digital zoom function? Today’s nickel metal hydride rechargeable batteries are very powerful and last for around a 1,000 charges so always use these if you want to save money. Although most are supplied with a number of photo functions, try for as many as you can because you will appreciate the effects that can be achieved; just a few examples of functions to look for are shown here:
* Video capture * Time lapse (i.e. one shot every 5 minutes for example) * Self-timerHigh resolution cameras require more space to store images so you will probably need an additional storage card. Although larger storage cards have plummeted in price, a 1GB card should be enough for most peoples needs; some cameras won’t accept very high capacity cards anyway.
Cameras are now very tiny compared to a few years ago so you can actually carry around a high specification variant in your pocket and still be able to take fantastic pictures. Professional photographers may need heavy, bulky equipment but there is no requirement for a keen amateur to do so! Hopefully, these few tips will be enough to steer you in the right direction when you come to buy your camera. With all its technology, versatility and portability, the digital camera is the future of photography.
