According to the Nikon D70s manual (page 51), temperature values for
white balance presets are:
Direct Cloudy Shade
Incandescent Fluorescent* sunlight Flash (daylight) (daylight)
+3 2,700 K 2,700 K 4,800 K 4,800 K 5,400 K 6,700 K
+2 2,800 K 3,000 K 4,900 K 5,000 K 5,600 K 7,100 K
+1 2,900 K 3,700 K 5,000 K 5,200 K 5,800 K 7,500 K
0 3,000 K 4,200 K 5,200 K 5,400 K 6,000 K 8,000 K
- -1 3,100 K 5,000 K 5,300 K 5,600 K 6,200 K 8,400 K
- -2 3,200 K 6,500 K 5,400 K 5,800 K 6,400 K 8,800 K
- -3 3,300 K 7,200 K 5,600 K 6,000 K 6,600 K 9,200 K
* The size of the increments for Fluorescent reflects the wide variations
in color temperature among the many different types of fluorescent light
source, ranging from low-temperature stadium lighting to
high-temperature mercury-vapor lamps.
UFRaw uses incorrect values when the --temperature option is not passed
to it via the command line. For instance, according to the above chart,
WhiteBalance = CLOUDY should use 6000K but UFRaw uses 5413K.
It also ignores the Fine-Tuning in the WB value
("0x000b Nikon3 WhiteBalanceBias SShort 1"
in exiv2 -pv). The correction is not applied at all. For example, as
per the above chart, WhiteBalance = INCANDESCENT with a fine tuning of 3
(WhiteBalanceBias = 3) should use 2700 but UFRaw uses 3030K (even with a
WhiteBalanceBias of 0).
Also, the increments in temperature from WhiteBalanceBias = 0 are not
constant and should not be interpolated (The Nikon D2X values set in
wb_presets.c in UFRaw aren't interpolated but used as-is from the tables
I suppose).
