--- Comment #8 from Regina Henschel <rb.henschel at t-online.de> ---
The topic of this issue is not clear to me: What have you done step by step,
what do you expect to get, what do you actually get?

But nevertheless some "thoughts".
There are issues open in ODF regards luminance.
https://issues.oasis-open.org/browse/OFFICE-3821
https://issues.oasis-open.org/browse/OFFICE-3833

In ODF luminance is a non-destructive filter. The image in the file is not
changed by the UI setting, only the information about the setting is stored.
The user can change the tone adjustments and will always have the original
image inside the document package.

In Word tone adjustment is applied to the image. So the user cannot go back to
the original image. Because the tone adjustment is already applied, a
draw:luminance attribute is not needed, when Word exports to odt.

The draw:luminance domain is -100% to +100% with 0% meaning no change. So a
draw:luminance=0% needs only to be written, if you want to prevent inheritance
from a parent style.
