What is the primary difference between luminance noise and color noise in digital images?
- Luminance noise affects the brightness of pixels, while color noise affects the hue and saturation.
- Luminance noise affects the color temperature of an image, while color noise affects the contrast.
- Luminance noise is more visible in low-light conditions, while color noise is more visible in high-contrast scenes.
- Luminance noise is caused by sensor defects, while color noise is caused by lens aberrations.
