The Histogram Palette in Photoshop is a tool that allows photographers and editors to adjust the tonal values of an image. It provides controls to modify the white, middle gray, and black points, helping to fine-tune exposure and contrast.
Unlike the histogram in Photoshop's Levels command, the Histogram Palette is accessible while using other tools, offering continuous visual feedback. Understanding this palette helps photographers make precise tonal adjustments, ensuring well-balanced images with improved detail in shadows, midtones, and highlights.
