Digital still cameras store photographs as digital bits on a memory card or tiny hard drive. However, as opposed to the film used in traditional cameras.
Rather than developing and printing film, digital images can be downloaded easily to a computer. Generally, a photographer also can instantly review shots on an LCD (liquid crystal display) monitor built into the digital camera. Therefore, memory cards can hold a large number of images. After downloading the images to a computer, the flashcards can be erased for reuse.
The main drawbacks to digital still cameras are:
A slight delay that occurs between clicking the camera’s shutter button and the camera actually taking the picture. The better the camera, the shorter this delay will be. Professional digital cameras do not suffer from this lag time, and the problem is becoming less pronounced. Generally, this even with cheaper consumer/prosumer cameras.
A battery is required for operation, so you’ll need to periodically recharge it (this can be done by connecting the camera to an AC power adapter and charging the battery in the camera, or by purchasing a separate AC battery charger).
Photos that are not quite as high quality as what you get with traditional single-lens reflex (SRL) cameras. But, unless you purchase a very high-end (and expensive) digital camera. But, even a mid-range digital camera produces photos that are suitable for the vast majority of purposes. This also is including Web publishing.
