Hello, i'm using DCRAW lib with imageen, and i want to display the RAW picture without debayering it (no color, no interpolation);
when i use the '-d -v' option, i get an error message and a strange pic (from dng or CR2 file):



Somebody did try to get the original RAW file without any color interpolation ?

You're out of luck, I'm afraid:

i did find a solution (that i dont like, but no other choice today):
- i use dcrawlib.dll to import a RAW file into imagenview
- i use dcrawMS.exe to export a Black&white RAW file (tiff)
- i load the bW tiff file in imageenview
so i need two external programs !...
if anyone know how to do it better...
Thanks

Exactly what I did, too. Although I use a DCRAW executable to obtain the necessary values to control and correct saturation levels.

What do you mean? Luminance noise? I just use the -n option in combination with a user defined numeric value.
