I just shot some before sunrise and after sunset shots on a 1DsmkII and Kodak SLR/n at 6 iso, I bracketed a few stops when possible. Both showed banding in the sky with the transition from light to dark. Would a MF back of avoided this? Would those extra bits and larger sensors given me a smooth transition? All raw.
I'm wishing I'd shot on film at the moment it was -5 degrees C, I hate to think my early morning efforts have been spoilt by modern technology!
Exposures were quite a few seconds in each case, 60 secs with the Kodak, but it does have a special setting for this.

Kevin:
A MF camera back would not show the banding because most of them are capturing at least 14 bits per color, Phase One P backs are capturing 16 bits per color. Any camera with more dynamic range will also produce smoother ramps which never show as bands of missing information.
Your Canon camera is a 12 bit capture device and will show banding more often when the light extends from one extreme to the other. For many years it was easy to duplicate this when comparing various MF manufactures backs to customers at the same time. You can duplicate this in the studio with one light on a background feathered off so you can see it start to focus and then fall off.
There are so many people that think because a manufacture states in the sales propaganda that their camera is 12 bit or 14 bit. Many early designed camera and camera backs were using analog to digital converters to reach the dynamic range that was stated. It was always easy to show this when comparing Phase One backs to Megavision. And comparing Leaf backs to Kodak Pro backs.
So all that hype about MF backs is true, you will find the tonal range is smoother because you are comparing 4,000 shades of color to 16,000 shades.
