Please show me that what arethe chracteristics of professional camera. Professional camera? Well, professionals most often use SLR (Single Lens Reflex -- it means that what you see in the view finder is actually looking through your lens rather than through a separate view finder) digital cameras with interchangeable lenses. You want it to be fully automatic and have all the manual options as well. You would want 8.0 mega pixel or so. That is what determines the clarity of the pic. With a professional camera you should be able to take a relatively wide shot and blow up the pic to show a very small portion of it and still get a clear pic. Get one that can take a high number of frames per second. Pros will often snap several shots at a time so as not to miss that special moment. Also look for something with almost no delay. Nothing worse than pointing and clicking and by the time you wait for it to capture, the moment is gone. Get lots of memory to hold all of those rapid fire photo sessions on while you're waiting to get them back to your photo-editing studio, which is a computer with photoshop and a professional photo printer. Get an extra battery so you don't run out when you need it most, right in the middle of that big African safari documentary your doing a photo journal of. And of course you'll want to get as many accessories as you can get your hands on, like every light filter known to man, a flash for every situation and a good tripod and telephoto lens to catch all those celebrities at their worst. For just the camera and the a lens your looking at $800-$1200. With all the goodies it's easily thousands and thousands.
Of course the average person does just fine with a point-and-click type camera. Spend a few hundred dollars on a nice one and look for the options that make sense to you for your picture-taking style. I personally like the ones with little or no hesitation between when you push the button and when it captures the picture. 6.0 mega pixels should be fine and will allow you to zoom in on photos taken pretty far. Look at some of the specs like battery life and compare them to other cameras of similar price. Look at what kind of memory card it takes, how much it will hold, and how much the cards cost. Good luck. And have fun.
