Exposure Triangle

This self-paced elearning course equips surveillance professionals with the skills to move beyond auto mode and take full control of their camera using the exposure triangle—aperture, shutter speed, and ISO. Designed for real-world fieldwork, this training emphasizes how to quickly adjust camera settings to capture sharp, usable evidence in unpredictable conditions, including low light, fast motion, and long-range observation.

Through tactical examples, field-tested tips, and interactive scenarios, learners will build confidence using manual and semi-manual modes to produce clear, professional-grade surveillance images. Whether documenting suspects from a vehicle, tracking movement on foot, or working in variable lighting, this course bridges the gap between owning a camera and using it effectively as an evidence-gathering tool.

When you have completed this course, you will be able to:

• Explain how each component of the exposure triangle: aperture, shutter speed, and ISO,
  contributes to image exposure.
• Recognize how changes to one camera setting affect the other settings and image quality.
• Select appropriate settings based on lighting and subject requirements.
• Explain how aperture, shutter speed, and ISO work together to create proper exposure.
• Identify exposure problems such as underexposure and overexposure.
• Match exposure settings to specific lighting scenarios.
• Apply exposure triangle principles to achieve balanced exposure in example situations.
• Analyze basic shooting scenarios to determine appropriate exposure settings.
• Select exposure adjustments to compensate for changing light conditions.
• Identify setting combinations that support clear, usable images for evidentiary purposes.
