How to use flat field correction?

Flat field correction is used to correct uneven backgrounds caused by microscopes or illumination. Please first remove the sample and capture uneven background images. Then place the sample on the microscope and enable flat field correction. Please make sure to remove the sample when taking background images.

When conditions change, including optical systems, illumination, exposure time, or gain, FFC must be performed again under new conditions.

First remove the sample to obtain uneven background.
Set the number of background images. These uneven background images will be averaged and used as reference for FFC.
Click the "Enable" button when the "Enable" button is grayed out.
