The No-Flash shooting mode is not on option on all cameras, is seldom used, but is useful when used.
Primarily used in low light situations, the No-flash mode prevents the flash from firing. This is most useful when the flash is creating harsh light on the subject, or when you want to avoid red-eye on your subject.
BENEFITS
- For inexperienced photographers, the camera chooses ISO sensitivity, Shutter Speed, and Aperture for you without the flash firing.
DRAWBACKS
- In low lighting situations, the camera might not be able to boost ISO high enough to take the photo.
- Also in low light, the camera will boost the ISO setting to one of the higher values possible, thus introducing digital image noise into the exposure.
