Gain (User-Defined Exposure, 8 bit and 24 bit)
When you define your own Exposure, you can enter the precise gain that the camera will
use for an image capture. Unlike the Auto-Gain limit feature, which sets a limit within
which the camera can work, the Gain option defines a precise gain setting. As with
exposure, you can enter a specific gain in three ways:
§
You can manually enter the gain by selecting one of the five gain options from the
selection list.
§
You can let the camera compute the best gain (and exposure times) by using the
Compute Exposure feature.
!
Note: Refer to the previous section for details on using the Compute Exposure
feature. The gain displayed in the Exposure window is automatically saved to the
image setup that you specify.
§
You can use the Recall Previous Exposure feature to recall the gain from the previous
image capture.
!
Note: Refer to the previous section for details on using the Recall Previous
Exposure feature.
To manually enter a gain, follow these steps:
1.
Ensure that the User-Defined Exposure option is checked.
2.
Ensure that you are using either the 8 bit or 24 bit image depth setting.
3.
Select one of the five gain options from the list.
