Remember there are no rules in photography, there is no right or wrong way to take a photograph, how you want your pictures to look is completely up to you.
The best camera
The best camera is probably the one you already have, in fact most people carry a camera around with them all the time and don't even realize it!
If your not happy with the photos from your mobile phone or any other camera, then no amount of money spent "upgrading" will improve your photos.
What most people don't realize is that no matter how good the quality of the lens or camera, or how sharp it is, or any other technical detail, makes NO difference at all.
The only thing that matters is paying attention to the subject and learning the basic elements of light & composition.
Take a look at the work of Ansel Adams using an old glass plate camera or that of Cartier Bresson using a single fixed lens or photos taken on cheap toy cameras such as Holgas or on disposable cameras.
Even mobile phones, have cameras quite adequate for producing good photos, that you can print and hang on your wall. Why not take a look at:
5 or 6 megapixels is good enough to print A4 & A3 prints from. That was the resolution of my first digital camera. Some mobiles are approaching, if not even surpassing the 10 megapixels of my Pentax K10D that I use. Of course its not all about pixels, but that's another subject.
In the past you had to spend ages learning all the technical stuff to get good photos repeatedly. Today cameras are all automatic, focus first on your pictures and how to improve them by asking yourself, why are you taking the photo? and then altering the composition and framing. Don't focus on your camera, the camera doesn't matter. Only once you have learned to take photos you are happy with should you think of taking it off auto.
Trying to learn about your camera first will only result in learning about things that aren't relevant to what you are trying to achieve with your photography.
Concentrate on your pictures, the style, look, and subject that you want to make first, the technical side will follow naturally when you need it.
If you focus on your camera equipment you'll only end up spending money on stuff you don't need. Eventually after many years and a lot of money spent you'll get the photos your after, which you could have achieved with the camera, you first started with.
