Q
Q: What is ISO in photography?
Solution:
ISO measures the sensitivity of the camera sensor to light, affecting exposure and noise levels.
Steps: 5
Show Steps
Step 1: Understand that ISO is a setting on your camera.
Step 2: Know that ISO measures how sensitive your camera's sensor is to light.
Step 3: Realize that a lower ISO number (like 100) means less sensitivity to light, which is good for bright conditions.
Step 4: Understand that a higher ISO number (like 1600 or 3200) means more sensitivity to light, which is useful in darker conditions.
Step 5: Remember that increasing ISO can also introduce noise (graininess) in your photos.
