In photography, tone values refer to the various shades of gray between the extremes of black and white within an image. They represent the subtle gradations of brightness that contribute to depth, detail, and overall visual impact.
Understanding and controlling tone values is essential for photographers to achieve balanced exposures, emphasize textures, and create mood in an image. By manipulating lighting, contrast, and post-processing adjustments, photographers can enhance tone values to produce rich, professional-quality photographs.
