A Note On ISO
If you take a photography lesson with me, I will not spend much time about talking about ISO.
Why is that?
The answer is pretty simple.
You only ever want ISO to be the lowest that it can go. This post will look at why.
ISO Is Not Essential
You may hear photographers talk about the exposure triangle: (1) aperture, (2) shutter speed, (3) ISO.
In other posts I’ve talked about how aperture can help you with selective focus, and shutter speed can allow you to show movement.
To quote my photography teacher, Andrew Shapiro, “ISO is only ever a compromise.”
This means that you use ISO when a scene is too dark, but you want to have more options when using your aperture or shutter speed.
But there is no positive aspect to a higher ISO. A Higher ISO means that your camera sensor will be less sensitive to light, and you are more likely to get grainy photos.
ISO Is Not A Historical Part Of A Camera
Do you remember back to the days when people still commonly used film in cameras? We had to buy film that had different levels of sensitivity.
