ISO and Image Noise: The Decisions That Matter
The camera setting that amplifies the sensor signal, allowing shooting in less light at the cost of more visible noise.
Imogen Clarke
What is at stake
Keeping ISO low preserves image quality, which matters for product images that are zoomed and retouched.
The playbook
- Shoot at base ISO in the studio
- Add light rather than raising ISO where possible
- Test noise levels for each camera
- Apply noise reduction carefully in processing
- Keep ISO consistent across a set
Where it goes wrong
Avoid:
- High ISO in controlled studio setups
- Heavy noise reduction that smears detail
- Different ISO settings within one product set
- Underexposing and brightening later
The numbers behind it
| Measure | Figure |
|---|---|
| Base ISO | the setting with the cleanest image for a given camera |
| Higher ISO | more noise and less dynamic range |
| Studio work | controlled lighting allows low ISO |
| Noise reduction | can remove detail if applied heavily |
Getting outside help
When to hand it over: Bring in help when product images look noisy or soft at zoom.
