Curves Curves, also known as tone curves or contrast curves, are graphical representations of the tonal values in an image and the adjustments made to them. They allow users to adjust the brightness, contrast, and color balance of an image by manipulating the distribution of tones across the tonal range. In Giclée printing, curves are commonly used in image editing software to fine-tune the exposure, contrast, and color balance of prints, enabling precise control over the appearance and visual impact of the final output. |
