Brightness adjusts the overall lightness or darkness of your entire image. Increasing brightness makes all pixels lighter, while decreasing it makes everything darker. Use this to fix exposure problems or create specific lighting moods.
Contrast adjusts the difference between the lightest and darkest areas of your image. Increasing contrast makes lights lighter and darks darker, creating more dramatic separation. Decreasing contrast brings tones closer together for a flatter, softer look.
For best results, often adjust both: fix exposure with brightness first, then enhance detail separation with contrast.
