How to take a perfect picture using a digital camera?

Practice, and since you have a lot of memory, take several shots of the same thing, try different settings and angles, etc.

Stupid things lol, took me dang near a year to get half good with it, but they are neat thou

i don't know how you define "perfect"
but if you're pertaining to the quality,
probably you should use a tripod so you won't
get blurry shot.
and if you're pertaining to the photo itself
you'll be needing a lot of experience well not much actually
digicams are awesome because you can
shot hundreds and sometimes
choose the TWO most beautiful one.

There is no such thing as a perfect picture. You will find that there is always something that can be improved, no matter how hard you try.

You can, however, make your photos better by learning the rules of good photography. Learn composition rules , such as the rule of thirds, so you know how to place emphasis on your subject. Also learn how to set the camera's shutter speed, exposure, and focus manually, so that you choose how the camera captures the picture.

The art of photography is all about learning how to use the tools available to you to capture your subject in the best possible way.
