“Sensor Calibration” by Peterson

Each camera model has different exposure responses as it performs accurate long exposures or combines exposures for HDR. For optimum results, it is imperative to know your specific camera’s sensor response. This presentation explains sensor response, sensor noise, and how to establish the appropriate sensor response for your camera. Topics include:

• How does a camera sensor work?
• What is sensor noise?
• How to evaluate your camera sensor.
• What does sensor noise add to your image exposure?
• How to build an exposure-gain chart for your camera.
• Post noise control.
• Determining image-sensors limitations.
