Before taking photos, we will briefly introduce the basic techniques of photo-taking. This activity is about sensitivity (ISO).

Sensitivity (ISO) is a camera setting that will brighten or darken a photo. Taking photo at high ISO will show a lot of noise.

These photos were taken with an ISO value of 100, 200, 800 and 1600, respectively.

What are the characteristics of the photos taken with higher ISO values? What kind of feeling do they give?

The higher the ISO value, the more sensitive the film is to light. That also increases the noise in the photos and makes them look grainy. 

The lower the ISO value, the less sensitive the film is to light. There is less noise in the photos, and the photos look clearer with more detail.
