Exposure
Exposure relates to the amount of light that reaches the camera sensor when taking a photograph. It affects how light or dark an image appears. Overexposure makes an image too bright, while underexposure makes it too dark.
Contrast
Contrast is the difference in color and brightness between objects or elements in an image. Increasing contrast makes the bright areas brighter and the dark areas darker, while reducing contrast minimizes these differences.
Vibrance
Vibrance is similar to saturation but is designed to affect less saturated colors more than already vibrant colors. It helps to boost the intensity of muted colors while avoiding over-saturating already vibrant ones.
Warmth
Warmth refers to the overall color temperature of an image. Increasing warmth adds more red and yellow tones, making the image appear warmer (like sunlight), while reducing warmth adds blue tones, making the image appear cooler.
