Digital cameras produce digital pictures that are easy to load onto a computer and email around the world. Digital pictures are also easy to check and delete. So if it is obvious that a picture is hopeless it can be easily deleted rather than wasting film, which cannot be reused. Without the film, which can go bad with age, a digital camera that you keep handy in case of need is far more reasonable.
One way to characterize digital cameras is by image size. The pictures are made up of tiny dots of color, called pixels. This is expressed as a pair of numbers, height and width. An example would be 320x480. These numbers would then be multiplied together, and larger numbers are more detailed, but typically are on more expensive cameras.
At this point, two megapixels, essentially two million pixels, is on the low end and might result in noticeable defects when pictures are enlarged. Five megapixels is a robust picture that can usually handle enlargement well.
Another consideration is zooming. Optical zoom adjusts the actual light as it enters the camera to make the scene appear closer. Digital zoom adjusts the picture after it has been digitized to simulate a closer appearance. While both can produce acceptable results, optical zoom is preferred.
Digital cameras come with some internal storage. This is almost always too small. Thus the type of add-on storage the camera allows is important. In some cases you might possess other equipment that uses the same sort of gear, and compatibility is helpful. While there are several choices, this additional storage is typically a chip about the size of a thumbnail, allowing several to be conveniently carried if needed.
It is important to pay attention to the battery. Some cameras will use standard sizes, others will use proprietary or less common sizes. Some are better able to hold a charge, some cameras are power hogs, and some systems are rechargeable.
This brings us to the preview screen. This is an LCD screen that shows what the camera would see at any point, should you desire a picture. In this mode, the screen is active whenever you are considering a picture, which tends to consume batteries at an alarming rate.
Even digital cameras also come with an optical viewfinder that consumes no power. There are circumstances that make this superior, such as waiting for the correct moment to shoot, and circumstances that require the preview screen, such as composing a picture at a very awkward angle. The screen also allows you to preview the saved pictures and delete any that are unusable to clear storage space.
If you prefer to keep your photography easy then a point and shoot digital camera is for you. Now before you think you are going to be getting some substandard camera, let me reassure you that point and shoot cameras can take great quality photos. And, as the camera technology develops, point and shoot cameras are becoming of more interest to the experienced photographer as well. Of course, the advanced point and shoot cameras are juts a bit more expensive than your normal ones, which is why they are aimed at the serious hobby photographer. But, for your normal family photos a compact point and shoot digital camera is ideal. Following is a brief rundown of what you can expect from a point and shoot digital camera.
One of the main factors to having a good digital camera is its shutter speed, and this is what people used to believe was the downside of a point and shoot compared to a SLR digital camera. But as technology has evolved your standard compact camera has managed to decrease the delay of the shutter and you can now get much better quality photos. The one downside that still remains with point and shoot cameras is that when you zoom, you are not getting a lens zoom, but merely enhancing the digital image. What this means is that when you come to print the image, it can appear distorted. If this bothers you then you may have to look at using a SLR camera.
In the olden days of photography your image was on film. These days your image is on the memory card, and for that reason it is important that your memory card has enough storage for your needs, especially if you are going on vacation and will be unable to save your photos onto your computer. On the whole though if most of your pictures are taken when you are in your home town you do not need to worry about the memory card too much as you can put them on your computer the same day that you take them. Admittedly when you first start to look into memory cards you may find it a little bit confusing, but if you tell the person you are buying from how you intend to use the camera, they should be able to advise you on the right type of card to get. Finally, one of the last big advantages of this compared to normal photography is that if you make a mistake with the picture you are taking, you can retake the shot straight away without waiting for it to be developed and then seeing your mistake and not being able to do anything about it.
If you are new to the world of digital cameras then one of the words you are bound to have come across is megapixel. Basically for a normal point and shoot, to get decent quality you want a camera with three mega pixels as a minimum. Although these days, when you go to buy your camera you will find that most point and shoots have at least 3 or 4 mega pixels anyway. Now it is possible to buy a point and shoot with a lot more mega pixels, however if your camera is just for family snaps and vacations, going after more mega pixels is not going to make that much difference, except to your wallet.
