64MP AF QuadKit - Four Independent Pictures

What is the correct line of code to get the AF Quad Kit to take four focused images and save them as different files?

We do not have the necessary demo code to fulfill your requirement at this time. However, we can provide you with guidance on setting up a single channel by following the link below. You can then proceed to create the code according to your needs.

I mean having each individual camera module take a picture and save them individually. So four cameras, four channels, one arducam quad kit

Yes, you need to follow the link I post in my previous reply to switch the camera mode.
