INFO:

What is ISO and how does it affect your photos?: ISO refers to the sensitivity of your camera’s sensor to light. It’s represented by a numerical value, such as ISO 100. A lower ISO number indicates lower sensitivity to light, while a higher ISO number indicates higher sensitivity. Increasing the ISO allows you to capture images in low light conditions without needing a slower shutter speed or wider aperture. However, higher ISO settings can introduce digital noise or graininess to your photos, which can degrade image quality.
