szürkeárnyalatok

Szürkeárnyalatok, also known as grayscale, refers to a range of colors that are variations of gray, from black to white. In digital imaging and computer graphics, it represents an image where each pixel has a single value, indicating an intensity of light. This single value typically ranges from 0 (black) to 255 (white), with intermediate values representing different shades of gray. Unlike color images which require multiple channels (e.g., red, green, blue) to define a pixel's hue, saturation, and brightness, grayscale images are simpler and require less data storage. This makes them useful for applications where color information is not essential or for reducing file sizes. Grayscale conversion is a common image processing technique, often used in early photography, medical imaging like X-rays, and in various artistic or stylistic choices. The absence of color can emphasize form, texture, and contrast. In printing, grayscale refers to the use of black ink to create images composed of varying densities of dots, mimicking shades of gray. The term "szürkeárnyalatok" directly translates to "shades of gray" in Hungarian, reflecting this concept.
