for those of you who are still confused with the D800 and think the 75mb file size is a rumor look up page 436 of the D800 user manual

I believe you are still confused.
It says right there that 14 bit lossless compress is 41.3MB and you should have posted also page 86.
This for lossless compressed.
\"NEF images are compressed using a nonreversible
algorithm, reducing file size by about
35–55% with almost no effect on image quality.\"
ill spend 3300 on a d800e shoot the $$$ lenses at their sharpest settings, in places that i will probably never do back to again in my life,
I will not compromise for \"almost\" no loss in image quality
Argh.
Why aren\'t photographers at least computer literate for the basics by now?
Lossless compression has ALL the data an uncompressed file has. That\'s why it\'s called lossless. That\'s also why you don\'t get a change in shots remaining between uncompressed and lossless compressed (the encoding is a reversible algorithm, that sometimes doesn\'t make a bit sequence smaller). You can reconstruct the uncompressed file with this file,
Plain \"Compressed\" or \"lossy compressed\" (Nikon\'s naming doesn\'t help here) is visually lossless - this compresses the file by throwing away data from the highlight region (you generally don\'t need 8096 bits for the last stop of highlights when the best display methods (10 bit) can barely use 1024), so it gets rid of some of this and then compresses it.
