What is the correct method to adjust tonal range using Levels?

• A. Levels automatically adjust without sliders.
• B. Use Curves to adjust tonal range.
• C. Use Levels (Ctrl/Cmd+L), move the Input Shadow, Midtone, and Highlight sliders to stretch or compress tonal range while keeping detail.
• D. Copy and paste levels from another image.

Answer: (C)

Tonal range is controlled by remapping brightness values with Levels. In this tool, you directly set how the darkest parts, the midtones, and the brightest parts are mapped to new brightness values, which lets you stretch or compress the overall range while preserving detail. Open Levels (Ctrl/Cmd+L). The three input sliders represent shadows, midtones, and highlights. Drag the left slider toward the right to set a higher black point; this expands the range and increases contrast, but be mindful not to clip detail in the darkest areas. Drag the right slider toward the left to set a lower white point; this pushes bright tones toward white and also boosts contrast, again with attention to highlight clipping. Adjust the middle slider to fine‑tune gamma: moving it left lightens midtones, moving it right darkens them, so the overall brightness balance stays comfortable while the tonal range is reshaped. This method is ideal because it gives precise, manual control over how the tonal values are redistributed, letting you stretch or compress the range while keeping detail across shadows, mids, and highlights. If needed, preview clipping (by holding a modifier key) and use a non-destructive adjustment layer for flexibility.
