Camera White Balance

Hi Alex,

If I want to use camera white balance, should I use "-w" as "dcraw" originally has? It does not seem to be in "dcraw_emu". I can add it back if "-w" still has the same meaning.

Also, does "pre_mul" contain the white balance values either read from meta data or calculated by libraw?

If the white balance values can not be found in the meta data, I understand libraw will calculate them. If it is true, is there method that I can call to ask libraw to not calculate white balance?

Thanks a lot and have a great day!

Mio

From dcraw_emu, usage() call:

From dcraw_emu, usage() call:
"-w Use camera white balance, if possible\n"

And, sure, it works.
