Camera Specifications Guide Compiled By Jawad Ali 17/01/09 Cameras Types
We can divide all the different types of digital cameras into broad groups. If you are looking for a digital camera that is easy to use select the Simple and Easy group. Then you will find Standard cameras. These are cameras that can be used as simple point and shoot cameras, but tend to come with some additional/advanced features that you may find useful.
The Ultra Compact models are those designed to slip easily into a pocket or purse. These are normally easy to use cameras. Stylish cameras are models with metal bodies where there is an emphasis on design. With this group you will pay a premium for the build quality.
Then there are Advanced Compacts. These cameras are having a set of features that you would expect to find on a typical 35mm film SLR camera, but the camera retains a fairly compact shape. The Advanced Digitals have similar features as the advanced compacts, but are bigger and bulkier, built like an SLR camera.
A very small group is the Water Resistant models. These can be used in water to a depth of around 1.5m. Finally there are the Digital SLR cameras. These are advanced cameras that accept interchangeable lenses.

Pixels
One of the basic features of any digital camera is the number of mega pixels it is capable of recording. The more mega pixels it can capture the larger the size of print the camera can produce. These days we've digital cameras starting from 3 to17 Mega pixels.
Zoom
Another feature of a digital camera is the length of zoom. Normal zoom length is from 3 to 20.
Price
Price is always a key feature when you are looking to buy. You should choose other specifications according to your price range.
LCD Screen
A larger LCD screen can be a major help when you are lining up a shot. Screens vary in size typically from 1.5" to 2.5". There is a clear trend towards larger screens. Lcd screen sizes vary from 1.5" to 2.5".
Macro Distance
A macro facility helps you to take close up shots. Typical macro photos are of insects, text, flowers and jewelry. The macro distance is the distance from the subject that the camera is capable of focusing. The shorter the distance the closer in the camera can get.
Memory Cards
Memory cards are used by digital cameras to store photos and movies. Most cameras can only use one type of card, but others can use two or more. The most important point to remember is that if you are buying an additional memory card it has to be compatible with your camera.
Batteries
There are basically two types of batteries that a digital camera uses. The first are standard AA batteries. The advantage of these is convenience. You can buy them more or less anywhere. The downside is cost. Despite advances digital cameras are still heavy users of batteries and it can help to keep the running costs down if you buy some rechargeable batteries and a charger.
The other common type of battery is Lithium Ion. The advantage of these is that they are rechargeable. A battery and charger is supplied with the camera. The downside is that it is expensive to buy spares.
Movie Resolution
Most digital cameras can shoot movies at either a resolution of 640x480 or a lesser resolution on 320x240. Cameras that can shoot at 640x480 produce movies that when played back cover a television screen. The selector allows you to specify that you want to list only cameras that produce TV quality movies.
Movie Duration
Many cameras now allow you to record individual movies up to the capacity of the memory card. Others may only allow you to capture footage for a much shorter time. For example three minutes. The selector allows you to specify cameras that record up to the capacity of the memory card.
Manual Controls
The more advanced cameras offer you manual exposure controls. This allows you to set the aperture and shutter speed settings. This is ideal for experienced photographers or anyone who would like to experiment with photography.
Wide Angle
A wide angle lens allows you to squeeze more into a picture. This type of lens is particularly useful for shooting groups of people and landscapes. Be aware that a low percentage of digital cameras are built with wide angle lenses and your choice of camera is therefore restricted.
Image Stabilization
Image Stabilization helps to compensate for any camera shake that occurs when a picture is being taken. Tiny gyroscopes within the lens help to eliminate or at least the blur that camera shake can create. This is also sometimes referred to as Vibration Reduction.
