TOP SECRET Konica-Minolta camera project LEAK. a STUNNER

"Only from the mind of Minolta" I guess, since a RAW file from my 11 Mpixel
Canon 1Ds is only 8 - 11 MBytes.

 

Then my understanding of RAW is way off. I would assume 3 channels at
12 bits per channel * 8 Mpix/ 8 = 36 MB.

Cheers,
Alan

Your math is correct for an uncompressed 8 Mpixel tiff file (though it would be
stored as 48 MBytes due to the way 10, 12 and 14 bit/channel tiffs are stored),
but RAW is just the base sensor data and it's also (losslessly) compressed so
it's much smaller. The files expand during the RAW -> Tiff conversion.

You can post on the digital NG and ask a guy named Preddy to explain the pros
and cons of Bayer interpolation if you want to learn more

Thks for the clarification. I assumed it was not compressed (losslessly
or otherwise).
In a past life I spent a lot of time doing bandwidth optimization for in
flight data recorders and playback via RS-232 to the minicomputer on
which we criunched the data... very 'tailored' bit assignements resulted
in about a 25% 'reduction' in xmitted record sizes. Due to the very
simple processor in the recorder, a more ambitious lossless compression
could not be attempted. I'm surprised that TIFF doesn't have header
tags to define pixel BW allowing more efficient packing of the the data...

Preddy wastes enough bandwidth already.

A stunning camera!
