5 of 5UniWB Revisited

1/640s - maximum exposure with Uni WB, but captured with Auto WB: first shutter speed where green channel clips. Green values in RAW: 6-5118

This is just a sanity check. If the green values were different from the previous 1/640s exposure, the green channel values would be bad. Setting different white balance on the camera should not affect RAW values.
