Contrastcorrectie

Contrastcorrectie is a Dutch term that translates to "contrast correction" in English. It refers to the process of adjusting the tonal range of an image to improve its visual appearance. This typically involves manipulating the difference between the darkest and lightest areas of an image. In digital imaging, contrast correction is often achieved through software algorithms that analyze the histogram of an image. The histogram represents the distribution of pixel brightness values. By stretching or compressing this histogram, one can increase or decrease the overall contrast. Common techniques include auto-contrast, which automatically adjusts the levels, or manual adjustments where specific shadow, midtone, and highlight values are altered. The goal of contrast correction is to reveal details that might be obscured in areas that are too dark or too bright, making the image appear more visually appealing and easier to perceive. Over-correction can lead to a loss of detail or the introduction of undesirable artifacts.
