The snapImage() call will only snap an image from the current camera
(whatever you set via mmc.setCameraDevice()), so you need to call
snapImage() for each camera.

Currently the only way to do a simultaneous snap from more than one
camera is to use the Multi Camera virtual device (in the Utilities
device adapter).

Unfortunately the Multi Camera device is designed for use with
identical cameras, so there may be some rough edges, but I think it is
possible to control two different cameras. The downside is that the
images will be padded to match the larger camera.

Best,
Mark
