The LCD screen that is found on the back of digital cameras comes in very handy indeed. It has two functions. First it displays menu options. For example it controls the deletion of images that you don't want to keep.
Its main function is that it allows you to see the picture that you are about to take before you take it and how it turned out afterwards. For me this is one of the biggest advantages digital cameras offer an inexperienced photographer.
The ability to see exactly how you picture turned out immediately after taking it allows you to identify areas that you can improve on. It can also allow you a second chance with a photograph. If you take it and don't like the look of it you can always delete the image and take the picture again.
Changing batteries in digital camera
It is certainly true that all digital cameras use batteries very quickly indeed. There is some good news though in that the latest digital cameras are a lot more efficient in the way that they use power and this means that batteries last a lot longer.
There are also one or two things that you can do to conserve the life of your batteries and get more out of them. The simplest way is to turn off the camera when it is not in use. I know that this sound obvious, but it can be tempting to leave digital cameras running so that you are always ready to take your next shot. Another tip is to turn the LCD screen off when it's not in use. The LCD screen is a big power user and therefore can run your batteries down very quickly. From my own personal experience I am also well aware that overuse of "movie mode" on digital cameras can drain the life out of a battery quicker than anything.
More and more digital cameras will also take rechargeable batteries. These can be either Nickel-Cadmium rechargeables (NiCD) or Nickel Metal Hydride rechargeables (NiMH). O.K. there is more to pay up front with the cost of a recharger and the batteries themselves, but it won't be long before the investment has paid for itself many times over. If you are a heavy user of your digital camera then I would recommend buying two sets of rechargeable so that you always have one charged and ready for use.
