Episode notes
ISO As Sensor Sensitivity
- ISO controls the sensor's sensitivity to light and functions like opening blinds to let more light in.
- Increasing ISO makes the sensor accept light faster, effectively brightening the image without changing aperture or shutter speed.
Don't Set ISO High By Default
- Avoid cranking ISO unnecessarily because high ISO introduces grain and degrades image clarity.
- Prioritize capturing the moment over perfect technical quality when light is poor.
High ISO Tech Expanded Possibilities
- Modern camera sensors handle high ISO far better than earlier digital and film-era limits.
- This progress expands shooting possibilities that weren't practical a few years ago.
