Brightness linearly increases or decreases all pixel values, similar to screen brightness. Exposure simulates camera exposure compensation, affecting highlights and shadows differently β increasing exposure pushes highlights toward white faster while lifting shadows more gently. For underexposed photos, use exposure first; for overall dark images, brightness is more appropriate.
Temperature adjustment changes the red-to-blue channel ratio to simulate different light source color temperatures. Increasing temperature (sliding right) makes the image warmer (yellow/orange), simulating sunset or incandescent light. Decreasing temperature (sliding left) makes it cooler (blue), simulating overcast or fluorescent light.
Highlights adjustment only affects brighter areas β it can recover detail in overexposed skies or tone down bright spots. Shadows adjustment only affects darker areas β it can brighten shadow details without affecting overall brightness. Using both together can achieve an HDR-like effect, preserving detail in both highlights and shadows.
