On another note: I tried SNS on a 5Ds raw file and it opened fine with the current dcraw installed.
Canon to release firmware 1.4.15 to enhance dynamic range
The engineers at Canon have realised that while 50MP is great for many photographers, there is also a need for even greater dynamic range too. Cleverly they have managed to combine the output of multiple pixels in a unique way to get enhanced dynamic range and up to 48-bit RAW resolution. Canon is coining the term Dynamic Super Range (DSR).
Due to the unique way that CMOS sensors are accessed directly on a pixel by pixel basis it is possible to change the amplifier gain of each pixel in turn. Using this capability Canon engineers have managed to combine up to four pixels to create a dynamic super range (DSR) pixel with 48-bit pixel depth. In regular mode the camera uses 14-bit data per pixel for 16,384 discernible levels of tone at each pixel.
In the new DSR mode up to four pixels are treated as one and provide an incredible 48-bits of usable tones thats 281,474,976,710,656 levels. This will ensure that banding in smooth blue skies is a thing of the past.
