Receptor exposure was formerly called:

Receptor exposure was formerly called:

• A. Contrast
• B. Detail
• C. Density
• D. Distortion

Answer: (C)

The main idea here is that receptor exposure measures how much radiation reaches the image receptor, which directly determines how dark the image will look. More exposure makes the film darker, less exposure makes it lighter. Historically, that darkness level was called density, so the term receptor exposure was formerly known as density. Other terms describe different aspects: contrast is the difference in brightness between areas, detail refers to sharpness or resolution, and distortion is about geometric misrepresentation. That’s why density is the best answer.
