PanasonicRaw_CameraIFD Tag 0x1104

[Klaus_Homeister]

Hi Phil,

This Tag is set, when camera shoots on lowest possible Extended-ISO.

On G-Cameras this is at ISO 100 and the value here gets 256...
and on Compacts it is at ISO 80 and the value here is 171.
All other settings are 0 here.

To activate Extended-ISO in camera setup isn't enough.
The shot must be done in that range.

-Klaus


[Edit]
after changing camera-setup to 1/3 EV Step there is:

DMC GX-8

ISO 100  value 256
ISO 125  value 171
ISO 160 value 85
ISO >=200 value 0

I think its EV-Steps below Base-ISO (200 on GX-8).

value divided by 256.0f is...
ISO 100  -1.0  EV|ISO-Step
ISO 125  -0.667  EV|ISO-Step
ISO 160  -0.333  EV|ISO-Step

Hi Klaus,

I'll make a note of this in the code, but I don't know how/if this should be decoded.
