A way to make one of the channels be the AF channel with the result being used in subsequent channels for that location. For instance, if we are doing blue, green, red imaging at each location, use Blue’s AF result for the green and red images. Furthermore, an offset for the subsequent channels from that original blue AF result. So Green might be +12 microns and Red is -2 microns from the blue AF result. This might be a checkbox under the channels that is called "Relative Focus" with a field for micron offset. The user is responsible for insuring a Saved Focus or AF result in a channel prior to the Relative Focus channels at that location.
