6.2 Camera Settings for Manual Flash
Since the iM20 does not support TTL function or High-Speed Sync (HSS), manual camera settings are crucial for proper exposure.
- Vitesse d'obturation : Set your camera's shutter speed to less than 1/200 second to avoid synchronization issues or dark edges in your photos.
- ISO Setting: Start with ISO 100. Adjust ISO upwards as needed based on ambient light conditions to prevent underexposure. Be aware that higher ISO settings can introduce noise.
- Réglage de l'ouverture : Adjust the aperture to control depth of field and exposure. Use a larger aperture (e.g., f/2.8) for shallower depth of field. Use a smaller aperture (e.g., f/5.6 or f/8) for greater depth of field or in bright ambient light.
7. Entretien
- Nettoyez le flash avec un chiffon doux et sec. N’utilisez pas de solvants ni de nettoyants abrasifs.
- Rangez le flash dans un endroit frais et sec lorsqu'il n'est pas utilisé.
- Rechargez régulièrement la batterie pour préserver sa durée de vie, même si vous ne l'utilisez pas fréquemment.
