What Is ISO Speed?

Masterclass 4

Description

People often ignore ISO because they don't fully understand what it does, but once you do, you'll be making use of this clever tool all the time - and not only in low light conditions.

ISO is a kid of bonus exposure control which can help you out of all sorts of tricky situations.

In this video we'll explain

  • ISO introduction
  • How ISO works
  • ISO range and shooting in low light
  • Grain and noise
  • When to use ISO rather than flash

Instead of using flash for this indoor portrait I increased the ISO speed to make the camera more sensitive to light. Why would I not use flash?

Small on camera flashes have a nasty harsh look to the lighting which looks so stark and unflattering. Watch the video and you'll see what I mean. As far as I'm concerned ISO speed is king.

Although I was an early adopter of digital, I never acquired the confidence with digital as I had with film. This is why I started with the Ultimate Beginner's Course. I still need practice but I'm feeling much more confident now. Thank you for creating a course that actually goes into the field rather than just parking yourself in a studio and giving lectures.
