When processing a freshly exposed sensitometric strip daily, what instrument should you read it with?

Explanation:
Reading a freshly exposed sensitometric strip daily relies on a densitometer because the goal is to measure optical density—the amount of light transmitted through the developed film. The densitometer provides a numeric density value, which feeds into the sensitometric (H&D) curve used to monitor processor performance, film speed, and overall image quality. Other instruments don’t measure density: a spectrophotometer analyzes color or spectral content, while calipers or thickness gauges measure physical dimensions. Therefore, the densitometer is the appropriate tool for this task.
