Symptoms
- Photos look washed out and overly bright
- Photos look too dark even in decent lighting
- Exposure seems inconsistent between similar shots
- Auto mode produces unexpected brightness levels
Likely causes
- CommonExposure compensation accidentally set away from zeroA small dial or menu setting can bias every shot brighter or darker.
- CommonMetering mode not suited to the scene, like backlit subjectsDifferent metering modes read the scene's brightness differently.
- PossibleManual exposure settings left from a previous shooting situationSettings from indoor low light can overexpose bright outdoor scenes.
- PossibleFlash compensation set too high or lowCan throw off exposure specifically in flash photos.
- Less commonLight meter or exposure sensor malfunctionWould cause consistent errors across all modes and settings.
What to do
- Check the exposure compensation setting and reset it to zero if it's been adjusted.
- Switch to a general or evaluative metering mode for typical scenes.
- If shooting in manual mode, double check shutter speed, aperture, and ISO for the current lighting.
- Reset the camera to default settings if you suspect several settings have drifted from earlier changes.
- Test in fully automatic mode to see if the camera exposes correctly on its own, isolating a settings issue from a hardware one.
- Check flash exposure compensation separately if using flash and results seem off specifically with it.
- If automatic mode also consistently over or underexposes with no unusual settings, have the metering system checked professionally.
When to call a pro
If even fully automatic mode consistently produces wrong exposure with no unusual settings applied, a camera repair shop can check the metering system.
