What does 8.1 megapixels mean?

Question

i got a new camera and i dont know what 8.1 megapixels mean help plz and if i buy a 4gb card will it work with it

Answer 1

8.1 megapixels refers to the native resolution of the camera.

Camera pictures are compressed, so each picture is far smaller than the native resolution. Yes a 4 GB card will work.

Answer 2

yes a 4gb card should give u quite a few photos. it all depends on what quality level u have ur camera saving the pictures at as to how many you will be getting on the card. with mine i can range anywhere from like about (just a average) 1000-100 pictures 1000 being on the lowest save setting, and the 100 is when it on the highest (raw)

The first source link will tell you all about mega pixels.  More is not really better because it requires more processing time, memory, and takes more time to transfer.

Pictures look good because many things are automatic like focus and compensation for light and red eye. You can make the pictures even better by knowing all there is to know about your camera and taking pictures under optimal conditions.

My camera has 5.2 mega pixel, but I use 3 most of the time because it gives great results, is faster, and takes less memory. Also, it only has a 3 x optical zoom and 7x digital zoom. I never use the digital zoom because making pictures larger works better on the computer. This is an old camera, but it impress everyone with the quality pictures it takes ... like magic.  

Many of the new cameras come with only an LCD display. Would suggest that you find one that has an optical view finder because the LCD is almost impossible to see in bright sun.

The second source link will help you clean the camera and battery contacts. Digital Cameras require lots of power. If the contacts are not really good it can cause lots of problems.
