It has been found out that Nikon has a diagnostic mode called DIAG
RAW in CP2500, CP4300, CP4500 (tested) and possibly E775, E885,
E990, E995, E5000 that allows for RAW file output. This mode can
be turned on
by a diagnostic program such as Opencam or Rawenabler. The
rawenabler is pretty straightforward - you can connect the camera
to the PC via USB, turn it on so it looks as a removable device,
launch a programm - it should identify the camera and then you can
switch raw mode on and off, turn the camera off, disconnect it and
use wherever you please.
You can find it here (along with the sources)
According to the author the program runs under Win 2000 and XP.
In RAW DIAG mode the camera writes two files for each shot - one is
a RAW file (though it has an extension .jpg or .tif) and the second
one is a normal picture. The RAW file is NOT in the .nef format. I
have contacted David Coffin ( http://www2.primushost.com/~dcoffin/ )
and he has added CP4500 RAW file support to his beta version of CRW
He will also include CP4300 and CP2500 RAW file support in his next
version of CRW.
Also the RAW-> nef converter is under development.

My understanding of the raw concept is the camera (such as the
canon g2)takes a pic that has no compression, white balance or any
other adjustments done to it It is the equivalent of pure film
negative What you are hoping that we will believe that a Jpg that
has been compressed and other adjustments made to it can be
processed in the same way as Breezebrowser can process a RAW image
and achieve the same result? Why hasn't Nikon let us in on this
"secret" It is a bit early for April 1st


The RAW file only has extension of .jpg or .tif depending on the camera current settings but is not Jpeg compressed file. For Nikon CP4500 it has a constant size of 5865472 bytes containing RAW 2288x1708 12-bit GMYC data from the CCD sensor:
000000-2CB8EF - information on GM pixels (2288x1708*12/(2*8)bytes)
2CB8F0-2CBFFF - zeros
2CC000-5978EF - information on YC pixels (2288x1708*12/(2*8)bytes)
5978F0-597FFF - zeros
