Overexposure which may be called “blown-out highlights” or “flared highlights” in photography discussions and may be due to brighter whites or reflective surfaces a bit like the White hip stickers with a black number imprinted on them. If there is overexposure in the image, then reducing the brightness value will help to even out the image exposure.
If your camera is focused properly, you are using AGC and the gain value is between 70 and 90 then you can adjust the Brightness under camera settings to reduce this overexposure.
- Go to Camera Settings | Parameters where you will find Brightness listed next to AGC Parameters (if you use manual gain this setting does not apply)
- Reduce the value in increments of 5 until you find a good image from trials of capturing images.
- Be aware that this will change as the sun moves so don’t forget about it.
Underexposure where detail is lost to shadows and may be called “crushed shadows” or “crushed blacks” in photography discussions. If there is underexposure in the image, then reducing the Gamma value will help to bring out some of the detail.
If your camera is focused properly and the gain value is between 70 and 90, then you can adjust the Gamma.
- Go to Camera Settings | Setup where you will find Gamma listed near the bottom (this will work when using AGC or Manual Gain).
- Make small adjustments in increments of .05 until you find a good image from trials of capturing images.
- Be aware that this will change as the sun moves so don’t forget about it.
