SUMMARY
Initially, the author struggled with ISO in photography, viewing high settings as detrimental. They learned that rigidly adhering to low ISO (like 100) could ruin shots by causing motion blur or missed opportunities in challenging light. The key realization was that ISO controls sensor sensitivity and involves a trade-off between brightness and image quality (noise, dynamic range). Properly exposed images at higher ISO can be cleaner than underexposed ones at low ISO that are heavily edited. This shift in perspective allowed for more confident shooting in varied conditions, balancing ISO with shutter speed and aperture.
TAKEAWAYS
ISO controls camera sensor sensitivity to light.
High ISO increases brightness but can introduce noise and reduce image quality.
Proper exposure is crucial; a well-exposed high ISO image can be better than an underexposed low ISO image.
Understanding ISO as a tool, not a setting to avoid, improves shooting in difficult conditions.
