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.
1. megapixels:
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.
A very important thing to look out for when you are buying a digital camera is to read the small print as it were in regards to the megapixels of the camera. You see a lot of digital camera manufacturers will try to trick you into thinking they're digital camera is capable of a higher number of megapixels then is really true.
What many digital camera manufacturers do is to print on the camera or in their manuals say six megapixels in big writing, but underneath there's writing where they will put something like five megapixels enhanced to six using software. If the camera states something along these lines the camera is not truly six megapixels at all. If the camera has to use software to enhance its number of megapixels it will not be as good as a true six megapixel camera.
How much zoom do you need?
How much zoom your digital camera should have is really going to depend on the sort of use you give your camera, so only you can make this decision. However it's important to remember that the more zoom you have the more you are going to be able to do with your camera.
Most digital cameras come with two different types of zoom, digital zoom and optical zoom. With digital zoom the more you zoom in, the more the total number of pixels in the image will decrease resulting in a considerable loss of quality. With optical zoom the number of pixels in the image stays the same because the camera will make use of its lenses to make the area you are focusing on bigger thus not losing quality.
Many digital cameras here too can be misleading since they will often state the maximum digital zoom in big letters on the camera without actually stating that it is in fact digital zoom, they will of course tell you that it is digital zoom so as to cover themselves legally but again only with very small print nearby.
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:
The powersupply is something greatly ignored when people buy digital cameras. People just don't consider it, yet when you think about it having a reliable power source for your digital camera is vital to make sure you don't ever run out of power right when you need your digital camera most.
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.
These batteries normally last longer than normal batteries, but you will still want to have at least one spare battery Pack. Because of the price of these batteries you will need to take them into account when you're purchasing your digital camera.
A few digital cameras have the capability of being able to take both their own specific battery pack and normal AA or AAA rechargeable batteries you can find at any supermarket.
When comparing different digital camera models remember to take into account all of these details. You should also read up on camera reviews on the different digital camera models you are reviewing to see how each camera compares to each other.
This is especially important if you are buying a high-end digital camera, since as I have mentioned there are other factors such as the digital cameras lenses that will affect the quality of the pictures the digital camera takes.
