Imaging Sensor and ISOLearn how the imaging sensor works and how to use the ISO as an exposure tool.
Imaging Sensor and ISODeveloped by Jason Tomaric, FilmSkills
The imaging sensor is the heart of the camera system. It converts light into the electrical signal that becomes the image we see on screen. But understanding how it works and its limitations will help you improve your cinematography.
This lesson is jam-packed with tips on how to get the most out of your camera by understanding how photosites convert light into an electrical signal, bayer patterns, chip sensitivity, and working with dual ISOs.
This lesson includes:
• 20:25 video
• Illustrated supporting text
