I need to communicate with somebody who can show me zeros and ones from a "RAW"

file. If some body has model that we can show the students,that will be

fantatstic! Thank you. Bob

<p>Adobe probably has some documentation or whitepapers about DNG format.

 

<p>Otherwise, I'd probably start with the <a href="http://cybercom.net/~dcoffin/dcraw/">source code for dcraw</a>.

 

<p>I came across <a href="http://regex.info/blog/photo-tech/nef-compression/">a fairly technical analysis of the compression used by NEF</a>.

 

<p>Who is the target audience?

Target Audience: Students in College photography classes. Jusy to get them to "visualize" the numbers game.

Books? So many good books on this topic as well (well diagrammed too, amazing!) as a trivial Google search for a raw file sample to download. At the 0's and 1's level all files look identical: raw, jpg, gif, text, MS Word, Excel, .EXE, whatever.

Do they already understand how a pixel is described? It's starts with on and off=black and

white=1 bit. 8 bit combinations of RGB filtered on's and off's create the gradients of color

in between from 0 to 255.
