Hi Phil,
0x0003 WhiteBalance
I checked this on GX-8 for all that newer custom-Settings
0 = n/a
1 = Auto
2 = Daylight
3 = Cloudy
4 = Incandescent
5 = Custom#1
6 = n/a
7 = n/a
8 = Flash
9 = n/a
10 = Black & White
11 = Custom#2
12 = Shade
13 = Kelvin
14 = Custom#3
15 = Custom#4

[Edit]
And just this minute I see that CameraIFD Tag 0x3300 is identical to this one her.
Hi Klaus,
Thanks. Do you see the values of 0, 6, 7 and 9?
Also, what is the difference between Custom#1/2/3/4? Can you get different Custom WhiteBalance values for the same camera, or are these for different cameras?

No! Like Exif-Lightsource those values look like 'not allowed'.

Thanks. I think I'll add your new "Custom" values as "Manual 3" and "Manual 4", and change the second "Manual" in the current decoding to "Manual 2".

You have 4 different places in WB-Menu wehre you can do "select white set" via selecting a grey or white area on the touchscreen.
The camera then makes a shot, calculates the gains, and keeps this resident in this storage-place until you make a new greyshot here. Additional there is the option to adjust the color from Green to Magenta and Amber to Blue.

some slight additions.
on CameraIFD Tag 0x3300 the value can be '0' and has the same effect like '1'=Auto.
on new G9 from pre-roduction I have found two Multishot-Samples in very strange light conditions with values '18' & '26' in Tag 0x0003 and both resulting in an value '16' on CameraIFD:0x3300.
I can not see any new Whitebalance-Mode in G9's Manuals.
So my assumption is that >=16 is an Error-Value.
maybe out of range of the metering-system.
Or it indicates that metering isn't consistent over all of the 8 Shot's of those Multishot-Images.
for now I say: every value >=16 is an Error.
-Klaus
Was 18 a daylight shot, and was 26 a black&white shot? (Unlikely, but I thought I would ask.)
- Phil
Both were Pixelshift shots of a nighttime cityscape with some bright neonlights.
And in both shots Kelvin is measured above 9800 degree - what can't be correct.
And up to now I can not decode data from Tag 0x1500-0x1516 ... but I am sure that those Tags contain data of the Lens-CPU measuring light and contrast of the scene -> in both shots they're complete zero (and _only_ in those two shots!).
The '26' _wasn't_ "Black&white"!
And the '18' wasn't Daylight.
So it doesn't work to say 16&10 for <something +B&W> or 16&2 for <unknown + Daylight>

Thanks.
