The student would use the contrast adjustment tool. This tool works by manipulating the tonal range of the image.
How it works:
- The contrast tool typically uses a histogram to represent the distribution of tones (pixels).
- By adjusting the sliders or settings associated with the contrast tool, the software can either:
- Increase contrast: This stretches the histogram, making the dark areas darker and the light areas lighter. This enhances the difference between the tones.
- Decrease contrast: This compresses the histogram, making the tones closer together and reducing the difference between them.
Increasing contrast makes the image appear more visually appealing and can highlight details that might be lost in a flat image.
