Basically a digital camera is a device use to capture pictures without the use of film. The lack of mechanical parts has meant that the size of these cameras is only dictated by the size of battery needed to power them. Since the images captured are in electronic form, this is a language recognized by computers.Of course, because the images are digital, it means that they can be stored, filed and manipulated using a computer or specialized printer. Although the images are stored in electronic form, there is no discernable difference in the picture you see when it is printed out.
Many similarities exist between the two types of camera because lenses are still required to capture light just the same as a film version. The only difference between a digital camera and film cameras is how they capture this light inside the camera itself. Up market versions us a different system again with a charged couple device, or CCD, being the capture system which transfers the light into an electrical signal. 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.
The price has been depreciating recently and one of the main reasons for this is the introduction of CMOS image sensors, While 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. Image quality is important or it will be waste of time taking them so look for the highest megapixel model within your price range,they can also provide prints that are larger without any degradation.
Where you have a choice, optical zooms on digital cameras are better than digital ones - always,portrait shots that require 'framing' are so much easier with a an zoom facility. this will save money on batteries that are disposable. 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,examples are listed below:
Sepia shotsMultiple exposures (on a single image) Mosaic effect shots
High resolution cameras require more space to store images so you will probably need an additional storage card. With higher resolution models now the norm, forget anything lower than 1GB of storage space if you want to save the image at the highest resolution.
If you are going to be taking your camera everywhere, choose a handy and portable model. Professional photographers may need heavy, bulky equipment but there is no requirement for a keen amateur to do so! I hope these few tips will help you choose a camera you enjoy using for a long time. The digital camera has reinvented photography for the masses and this is a trend that looks set to continue.
