What Is ISO Speed?
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.

I'm shooting raw images now, which I rarely did before. I understand the histogram better. I had experience with film photography and was comfortable there. 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.
