2. The main reasons for overexposure in Canon cameras
According to feedback from professional photographers and maintenance engineers, Canon camera overexposure problems are mainly caused by the following factors:
| Reason type | Proportion | Typical models |
|---|---|---|
| Improper selection of metering mode | 42% | EOS R5/R6 |
| Exposure compensation setting wrong | 28% | EOS 5D series |
| Auto ISO function abnormality | 15% | EOSRP |

| Sensor failure | 5% | Each model |
3. Five practical solutions
1.Adjust metering mode: Change evaluative metering to spot or center-weighted metering, especially in high-contrast scenes.
2.Use exposure compensation correctly: Appropriately reduce the exposure compensation (-1/3 to -1 stop) in a bright environment. The specific value needs to be adjusted according to the actual light.
3.Update camera firmware: Canon officially releases firmware updates regularly to fix known exposure issues. The following are the recently updated firmware versions:
| model | latest firmware | release date |
|---|---|---|
| EOS R5 | v1.8.1 | 2023-06-15 |
| EOS R6 | v1.8.0 | 2023-06-10 |
| EOS 5D IV | v1.3.4 | 2023-05-28 |
4.Calibrate using gray card: Use an 18% gray card for white balance and exposure calibration before important shooting to obtain more accurate exposure.
5.Check automatic ISO settings: Ensure that the automatic ISO upper limit is set appropriately to avoid overexposure caused by excessively high ISO values in bright environments.
4. Recommended settings in different scenarios
| shooting scene | Aperture priority mode | Shutter priority mode | manual mode |
|---|---|---|---|
| strong sunlight | f/8-f/16 | 1/500s or more | ISO 100-200 |
| cloudy weather | f/5.6-f/8 | About 1/250s | ISO 200-400 |
| indoor natural light | f/2.8-f/4 | 1/125s or more | ISO 400-800 |
5. Advice from professional photographers
1. Develop the habit of viewing the histogram to ensure that there is no "overflow" in the highlights.
2. Shoot in RAW format to retain more exposure information for post-production adjustments.
3. Clean the camera sensor regularly to prevent dust from affecting the metering accuracy.
4. In extreme light conditions, consider using an ND filter to reduce the amount of light entering.
