Buying a digital camera is no easy feat today because the market is filled with camera that more or less have the same function and purpose. This has made the process of buying a good digital camera very difficult. In case you are planning to go out and purchase a expensive digital camera, it is important you understand the following concept so that you are able to make a better and informed choice.
Most of the digital camera’s put on display in a shop or website are arranged according to their megapixels. Megapixels can be defined as ‘million picture elements’ or dots that make up a particular image. Therefore the number of pixels is simply the number of horizontal pixels multiplied by the vertical pixels. So how do you decide how many megapixels do you need? This completely depends on your need. If you only plan to upload your pictures to a web page then a 4 megapixels camera would easily suffice for you. Further, if you want to print the photos you have clicked, you will need a camera that has at least 5-7 megapixels.Lenses
There are two types of lenses namely zoom lenses and prime lenses. A zoom lens allows you to zoom in and out of the subject while a prime lens requires you to move closer to the subject in order to get a picture. So what is the benefit of prime lens? They are often much cheaper and offer sharper pictures because they have wider apertures (they can take in more light, therefore performing better in low light situations). This said a zoom lens offers you more versatility as you do not have to keep changing the lens to get the shot you want. Both zoom and prime lens are defined by their focal length.
Focal length is often measured in millimeters (mm) and shows the distance at which something is in focus. You have to remember that the lower the local length the wider the zoom and the larger the focal length the more the image is zoomed in. Prime lens have only one focal length while zoom lens has a range like 18-55mm. Hence a good understanding about the aperture and focal length of a lens will go a long way in helping you choose a good digital camera.
Before taking any picture, it is important that your camera focuses, works out the exposure and do many other things in order to record a image. The time taken from pressing the shutter release to taking a picture is called a shutter lag. All cameras have different shutter lags so make sure you check it in the store itself as a long shutter lag may require you a longer duration to click a picture. This might not be helpful in situations that require you to capture moments.
There are many kinds of memory cards that are available in the market today. It is a good idea to do your research properly so that you can choose one that suits your requirements the best. Some of the common types of memory cards include smart media, compact flash, micro drive, and memory stick, multi-media and secure digital among many others.
Most digital cameras offer a JPEG option and in general using the highest quality of JPEG images at the highest resolution works fine in terms of image quality. Other expensive cameras also offer TIFF or RAW format and are generally giant files that will occupy a lot of space on your memory card. One of the benefits of a digital cameras photography is that image is not processed inside the camera, allowing you to set white balance and other things at a later time.
Battery and Power
Some cameras work with AA size batters while others use a rechargeable Lithium-Ion battery and adapter. Both have their own set of merits and demerits and it is a good idea to choose one that is specifically made only for your camera. If you choose a camera that uses a special battery with its own charger, getting a second one is probably a good idea as one day you might forget to charge or be away from a wall socket too long or take more pictures for a longer duration than anticipated.
After you have taken some good quality pictures, you will probably want to transfer them to your computer for the purpose of emailing, editing, printing and archiving. Most cameras can generally be connected to your PC or Mac with the help of a USB. The best way to connect is if your camera acts a USB Mass Storage Device and all you would need to do is connect it to your computer to copy the image files.
In the end, remain that a digital camera is only as good as the owner. It is important that if you want to make best use of the features of your digital camera, you invest the required time and effort in understanding it in a proper manner. Click as many pictures as you can by experimenting with the various features of the camera, because in this field it is only when you do that you will learn photography more.
