When you hold a new SLR (single lens reflex) model digital camera, whether its a purchase or if its a gift, you hold an well crafted instrument that is designed to deliver very crisp, sharp, brilliantly colored photos. If you acquaint with the cameras technical aspects, there is a whole new world of photography that opens to you. The typical manual for the digital cameras can be quite intimidating. Personally, I have a couple of manuals for a small digital camera which I bought about two years ago. This camera can be used either in manual mode or automatic (point-and-shoot), and its basic guide has 32 pages, while the advanced one 144 pages. Luckily, camera manufacturers have now instructions in DVD format which is helpful. However, sometimes the technical terms discourage the new owners on getting close and personal to their new cameras. Its really easy to search on Wikipedia, and investigate a lot of technical terms, like mega pixels. If you see that while the more mega pixels your camera has, (like 12.1mp or 10.1mp), the sharper your image will be because of the more pixel information that is being recorded when you photograph, which means that you can have your photos magnified to, mural or poster size, as there is greater density of the pixel information and because the image will maintain its clarity if you magnify it at large sizes. The photos that are taken with not so much mega pixel data do appear grainy, and that is because there arent a lot of recorded dots of the color information. Some basic things you should learn about your camera: how to control the amount of light that is perceived in a scene. Simply, the aperture (opening) of the camera lens resembles the iris, enlarging to let light in the low light situations, while narrowing in for brightly lit scenes. You can control the amount of light while adjusting the f-stops for your camera lens. Basic stops range within f-1.2 to f-22. A lower number indicates low light situation. The high number shows extremely brightly situation, and the aperture has to be closed down, to let in less light so the image wont be over-exposed and also washed out. Other thing you should know is the ISO, the speed (ISO) at which the shutter of the camera closes and opens. You can control this speed. You simply switch by choosing the speed that you want. This thing is important if you are, shooting sports where your shutter is open just a tiny fraction from a second and you can capture the action without blurring. But, you may need the shutter to be open for longer periods that is if you are shooting some night scenes or some fireworks. How to select focal distance: This is the part of the camera governing how far from your subject is the lens. The SLR model is extremely versatile, and that is because only with the flip in a button, you could change the lenses quickly and with ease. You can change from panoramic shots to portraits or macro mode of ECUs (means extreme close-ups). Even if you want to start out using a basic lens that has a focal lenght of 18-55mm, learning about these effects will reward you with knowledge to take excellent photos. Your digital camera can take memorable and stunning photos if you reserve some time to get acquainted.
