The available grayscale of an imaging system is determined by which factor?

• A. Pixel Pitch
• B. Bit Depth
• C. Exposure Latitude
• D. Image Latitude

Answer: (C)

Grayscale range comes from how much tonal variation the system can represent, which is captured by its exposure latitude. When exposure latitude is wide, the detector and processing can handle a broad span of exposures without losing detail in shadows or highlights, so more distinct gray shades can be produced across the image. In short, the ability to map a wide range of brightness values to visible gray tones is what gives you the available grayscale, and that capability is what exposure latitude describes.
