Shot some faster ones, but this 2 second shot seemed to do the job. This slide has already been color corrected to the exact same specs as the prior base exposure.

Rattling through 5 or more stops has become autopilot for me in these circumstances anymore. I don't even think about it, just notch the shutter speed and fire again until I feel I've got all the range necessary for a blended result.

So now to put them together...
