Outside of using shutter speed to blur or sharpen an image, it can be used to control the brightness of a photo.
Quick shutter speeds: 1/100 and lower
Slow shutter speeds: 1s and higher.
It is suggested that as a beginner, when you want to adjust your shutter, you shoot in Shutter Priority, so that while you change yourshutter, your camera will automatically select your shutter.
Excellent notes 🙂
