The 3 Things You Need To Know Before Purchasing A Digital Camera!

If you want to purchase a digital camera, you really must have at least some idea of what you need to look out for and avoid. You don't have to be an expert, but you must at least know some basics to make sure you don't end up with an inadequate camera for your digital photography. The following is a series of things you need to understand and look out for, there there is less plus several things you must avoid.

The number of megapixels the digital camera is capable of:

With the exception of the high-end professional digital cameras of 12 plus megapixels, the number of megapixels a digital camera is capable of generally speaking is the most important quality factor when it comes to how good your digital photos will come out. In the case of the high-end digital cameras the lenses themselves will also play a very important part.

Now in regard to the number of megapixels, there is one thing you really do need to look out for. It is vitally important that you read the small print as it were on the digital camera. You see many digital camera manufacturers will have you believe there camera is capable of a higher number of megapixels then it really is.

For example some digital cameras will have in big print on the camera and or in its documentation say six megapixels, but underneath in small print it will say something like five megapixels enhanced to six using software. Basically this means that the camera is really only capable of five megapixels but the software in the camera will attempt to enhance the quality of the photos to six megapixels, this will never be as good as a true six megapixel camera.

A digital camera's zoom

You're going to have to decide just how much zoom your camera will need, for this think about the type of photography you want to take with the camera, if a lot of long-distance photos are going to be taken, obviously more zoom will be very useful.

Now there is another important thing to understand here, digital cameras come with two kinds of zoom: optical zoom and digital zoom. Optical zoom makes use of lenses within the camera to zoom in on objects. Digital zoom simply digitally makes the image bigger and in the process will lose you a considerable amount of quality.

Again just like with the megapixels of a digital camera, the manufacturers often try to mislead you by using big wording stating how much digital zoom the digital camera has but only mention that the zoom is in fact digital in small print.

In my opinion digital zoom is about as useful as mud, I'd much rather not use digital zoom and instead digitally enlarged the picture at home on my PC. This way I would be able to see exactly how much picture quality I would be losing and I would still have the original picture at full quality.

The powersupply for your digital camera:

It really is surprising just how many people never stop to think about this, but yet when you think about it, what could possibly be worse than running out of battery power right when you have a great opportunity to take great photographs?

AA and AAA batteries are the most common method used to power the lower end digital cameras. In many ways having this kind can be a good thing in that these batteries are cheap and easily replaceable at anytime.

Specially made lithium battery packs are normally used in the higher end digital cameras. Because of the fact these battery packs are specifically made for the cameras in question they are also normally considerably more expensive.

Since these batteries are normally somewhat more expensive you will also want to take this into account when comparing price on each different camera model. You do normally get the added advantage of a longer period of usage of the digital camera when using these battery packs.

It's not very normal but some digital cameras do exist that can take normal AA and AAA batteries as well as batteries specifically made for it.

If you take into account everything mentioned above when you compare digital cameras, you should have no problem in choosing a good camera for your usage. Also remember to check out on-line reviews as they will help you compare each camera.

Checking out on-line reviews can become even more important when you're looking to buy professional digital cameras, since lenses and other specifications for the cameras can make a lot of difference at this level.
