It is astounding the quality and features that are packed into a small digital camera. There are so many to choose from and lots of technical information. Deciding what is good seems bewildering. Digital cameras are relatively easy to use and in most cases can be set to automatic for good quality pictures to be taken. Some advantages of digital photography include the ability to view pictures as soon as they have been taken, ease of use, large storage capacities, and the variety available in all price ranges. Image manipulation for a better print is also easy with a digital camera.
A digital image is made up of a series of tiny square pieces positioned side by side in rows, with each piece being a distinct color. Each piece is known as a pixel. The number of pixels included in a picture dictates the quality. Generally, the more and the smaller each pixel is, the higher definition the image will be. A lot of consumers will purchase a camera according to the megapixel count.
A megapixel is equal to 1 million pixels. A 5-megapixel camera can produce an image with 5 million pixels. For a reasonable quality 4”x6” print, usually, only 1 megapixel is required, although most cameras have a higher count. A higher megapixel image allows better quality enlargements or edited photographs to be produced.
Screens on Digital Cameras
Screens on the back of digital cameras are used to view a photograph as soon as it has been taken. A picture may also be taken by viewing the screen rather than the conventional eyepiece. Stored images from the memory can also be viewed via the screen.
Power and Batteries
Digital cameras run on batteries in a variety of sizes. Some run on AA, in which case rechargeable batteries would be a good choice. Some models have a rechargeable Li-On battery and charger which allows the camera to be recharged via an electric power outlet.
Memory Cards and Storage for a Digital Camera
Images taken with a digital camera are stored in an electronic form either directly on the camera’s memory or a removal memory card or stick. Memory cards and sticks are available in a variety of capacities. Generally, the higher the MB size of the storage device, the more images can be stored. Although, images with a high megapixel count use more memory space than those images with a smaller count.
Software for Producing Prints
Software for transferring images to a computer for storage, editing, and printing is generally supplied with most digital cameras. A detailed instruction manual may also accompany the camera. It is a good idea to read through all information and get familiar with the camera’s functions and features to ensure images are suitable for their intended use.
Digital photography is very popular with a large variety of cameras available. A little research into an individual’s requirements before purchasing a camera will ensure the user can produce the required results and enjoy photography.
