Billedniveauer

Billedniveauer, often translated as "image levels" or "picture levels," refers to the way an image's brightness and contrast are represented. This concept is fundamental in digital imaging and photography. Broadly, billedniveauer describe the range of tones present in an image, from the darkest shadows to the brightest highlights. In digital terms, this is typically represented by a numerical scale. For an 8-bit image, each color channel (red, green, blue) has 256 possible values, ranging from 0 (black) to 255 (white). A billedniveau adjustment allows manipulation of these values to alter the overall appearance of the image.

Adjusting billedniveauer can involve making an image appear lighter or darker, increasing or decreasing its contrast, or bringing out detail in shadow or highlight areas. Tools in image editing software allow users to set specific "black points" and "white points," effectively remapping the existing tonal range to a new one. This can be crucial for correcting underexposed or overexposed images, or for achieving a specific artistic effect. Understanding billedniveauer is key to effective image manipulation and ensuring that an image displays its full tonal range appropriately.
