Learn ISO Settings Explained

What Is ISO Settings Explained?

ISO controls your camera sensor's sensitivity to light. Lower ISO (100-400) produces clean images but needs more light. Higher ISO (1600+) works in darker conditions but adds grain/noise.

Why ISO Settings Explained Works

ISO is part of the exposure triangle (aperture, shutter speed, ISO). When you can't open aperture wider or slow shutter more, raising ISO is your solution.

How to Use ISO Settings Explained

• ISO 100-400: Bright daylight, outdoor scenes
• ISO 400-800: Overcast days, indoor with good light
• ISO 800-1600: Indoor events, early evening
• ISO 1600-3200: Low light, night photography
• ISO 3200+: Very dark conditions, accept noise as trade-off
• Use Auto ISO with minimum shutter speed for handheld shooting

Common Mistakes to Avoid

• Keeping ISO at 100 and getting blurry photos from slow shutter
• Raising ISO unnecessarily when you could use wider aperture
• Fearing noise too much - a sharp noisy photo beats a blurry clean one
