What does the effect of using an Invert filter typically do to light areas in an image?

• A. Turns light areas dark
• B. Brightens all areas of the image
• C. Preserves their original brightness
• D. Removes colors completely from the image

Answer: (A)

Using an Invert filter in image processing alters the colors in such a way that light areas become dark and dark areas become light. This inversion occurs because the filter works by calculating the negative value of each color component in the pixel. For instance, pure white (maximum brightness) becomes pure black (maximum darkness), while darker shades transform to lighter shades. Thus, light areas in the image are turned dark, which aligns with the understanding of how the Invert filter operates on pixel values.
