Digitaalikuvissa

Digitaalikuvissa refers to images captured and stored in a digital format. Unlike traditional analog photographs which rely on film, digital images are composed of pixels, tiny squares of color that combine to form the overall picture. These images are typically created using digital cameras, smartphones, or scanners.

The process of capturing a digital image involves a sensor that converts light into electrical signals, which are then processed and stored as data. This data can be saved onto various storage media such as memory cards, hard drives, or cloud storage. The resolution of a digital image, measured in megapixels, indicates the number of pixels it contains and directly influences the level of detail and clarity the image possesses.

Digital images offer numerous advantages over their analog counterparts. They can be easily edited, manipulated, and shared using software and online platforms. The ability to instantly review captured images on a camera's screen allows for immediate correction of framing or exposure. Furthermore, digital images do not degrade over time in the same way that film can, ensuring their longevity when properly stored. Common file formats for digital images include JPEG, PNG, and TIFF, each with different compression and quality characteristics. The widespread adoption of digital photography has revolutionized how we capture, preserve, and interact with visual information.
