A digital camera takes still photographs or video and advanced ones take both, digitally, with the images recorded via electronic image sensors. The diaphragm and shutter allow the perfect amount of light for a sharp picture, and the image pickup device in digital cameras is electronic.Though CCDs are commonly used in digital cameras for saving picture, the latest ones use CMOS chips, which are little cheaper. The camera size also varies widely, and larger ones are easy to operate, while smaller and thinner models exude style, fitting easily into a pocket or a purse. However, larger cameras have more features, and are less expensive too, and have to be considered for making the best buys.These sophisticated cameras come with an optical zoom or/and a digital zoom. Optical zooms have a minimum of 3x length, though latest ones have up to 12x optical zoom. Digital zooms enlarge the pixels of a shot, making a bigger appearance of the subject, making the picture more pixilated. Optical zoom cameras are usually suggested, for beginners. DSLR (Digital Single Lens Reflex) and point & shoot are two other features to be considered. SLR camera allows lens changes, opening up diverse choices for photographers, and enable the use of different qualities of lenses, such as wide angle lenses or long focal length lenses, which effects the image quality enormously. Point & shoot is easier, using optical zoom, preferable for beginners. For best buys, it is necessary to determine that the camera offers adequate resolution for preferred print sizes.Further, it is good to find a digital camera with a viewfinder, as a few beginner models only offer an LCD to frame photos, which might not be perfect in a bright atmosphere, owing to unfavorable glares. Special scene modes are another feature of these cameras, which offer automatic settings such as beach, sporting events or indoors, in accordance to the scene.Image stabilization technology allows the photographer to capture moving objects with a remarkable sharpness. This feature is important for those who think to focus on sports pictures. Advanced digital cameras offer image editing to a great extent. Today, digital cameras find importance in many devices such as mobile phones or camera phones, PDAs and even in astronomical devices. Notable benefits of digicams include instant display, storage of thousands of images on a tiny memory device, deletion of images to free space and video recording with sound.Accessories that could be needed with a digital camera include memory cards, camera case, spare batteries, lenses (for DSLR), external flashes, reflectors, tripods or monopods and filters. The Internet offers informative facts and reviews that could be of big help in making digital cameras best buys.
