Beginner's guide to: ISO (film speed)

Fundamentals of photography Part 3: ISO
I take you through the basics of photography. In this episode I introduce you to ISO, also known as film speed.
What is ISO, where to find it and how to control it on your camera. I also discuss auto ISO and whether it is worth using.
This is a beginner's guide and is an easy to follow introduction to this important photographic control.

The sensitivity stays the same, it's the amount of gain that the image processor applies to the reading from the sensor before writing onto the sd card.

Can you make a video about ISO invariance?

Sensitivity to light, rather than film speed these days, I would have thought?
