Note
The exposure zones are related to the original image (un-rotated), and the names of the zones apply to the original image.
This means, for example, that if the video stream is rotated 90°, then the Upper zone becomes the Right zone in the
stream, and Left becomes Lower.
• Automatic: Suitable for most situations.
• Center: Uses a fixed area in the center of the image to calculate the exposure. The area has a fixed size and
position in the live view.
• Full
• Upper
• Lower
• Left
• Right
• Spot: Uses an area with a fixed size and position in the live view to calculate the exposure.
• Custom: Uses an area in the live view to calculate the exposure. You can adjust the size and position of the area.
Max shutter: Select the shutter speed to provide the best image. Low shutter speeds (longer exposure) might cause motion blur
when there is movement, and a too high shutter speed might affect the image quality. Max shutter works with max gain to
improve the image.
Max gain: Select the suitable max gain. If you increase the max gain, it improves the visible level of detail in dark images, but
also increases the noise level. More noise can also result in increased use of bandwidth and storage. If you set the max gain
to a high value, images can differ a lot if the light conditions are very different from day to night. Max gain works with max
shutter to improve the image.
Motion-adaptive exposure
Blur-noise trade-off: Use the slider to adjust the priority between motion blur and noise. If you want to prioritize low bandwidth
and have less noise at the expense of details in moving objects, move the slider towards Low noise. If you want to prioritize the
preservation of details in moving objects at the expense of noise and bandwidth, move the slider towards Low motion blur.
Note
You can change the exposure either by adjusting the exposure or by adjusting the gain. If you increase the exposure time,
it results in more motion blur, and if you increase the gain it results in more noise. If you adjust the Blur-noise trade-off
towards Low noise, the exposure will prefer longer exposure times over sensor gain when the exposure is increased, and
the opposite if you adjust the trade-off towards Low motion blur. Both the gain and exposure time will eventually reach
their maximum values in low-light conditions, regardless of the priority set.
Lock aperture
adjust the aperture size. You can, for example, lock the aperture for scenes with permanent light conditions.
Aperture : Use the slider to adjust the aperture size, that is, how much light passes through the lens. To allow more light
to enter the sensor and thereby produce a brighter image in low-light conditions, move the slider towards Open. An open aperture
also reduces the depth of field, which means that objects close to or far from the camera can appear unfocused. To allow more of
the image to be in focus, move the slider towards Closed.
Exposure level: Use the slider to adjust the image exposure.
Defog : Turn on to detect the effects of foggy weather and automatically remove them for a clearer image.
: Uses the entire live view to calculate the exposure.
: Uses an area with a fixed size and position in the upper part of the image to calculate the exposure.
: Uses an area with a fixed size and position in the lower part of the image to calculate the exposure.
: Uses an area with a fixed size and position in the left part of the image to calculate the exposure.
: Uses an area with a fixed size and position in the right part of the image to calculate the exposure.
: Select to reduce motion blur in low-light conditions.
: Turn on to keep the aperture size set by the Aperture slider. Turn off to allow the camera to automatically
