What is ISO — Camera ISO and the Exposure Triangle Explained [Ep 2]

Summary by Krater

This video explains ISO in filmmaking as part of the exposure triangle, covering how sensor sensitivity works, how it affects brightness and noise, and how to use native ISO for low-light shots.

From the video

Answers: What is ISO in filmmaking and how does it work?

• ISO in filmmaking
• exposure triangle
• camera sensor sensitivity
• dual native ISO
• film grain vs digital noise

What it concludes

• A higher ISO value makes the camera sensor more sensitive to light, resulting in a brighter image but introducing more noise and grain.
• Shooting close to a camera's native ISO yields the least noise and greatest range of color and detail.
• Some filmmakers intentionally use high ISO values to create analog-style noise and texture reminiscent of film grain.
