Asking someone with a thorough understanding of the topic is the
rationale behind asking the users. The large amount of GIMP users
and the assumption that there must be at least some among them with
a thorough knowledge led me to my proposal. Yes, it's not perfect,
but at least one step into the right direction. If you have an expert
I'd be glad if you asked him and reported back.
Another point that needs clarification is the use and meaning of the
word 'Value' in the Layer and Painting modes.

Elle Stone and Nicolas Robidoux, can you please also have a
look on this topic? Thank you in advance.

I'm not feared of Photoshop ;-) Can we assume for sure that the wording
there IS proper (using a wrong word just because PS uses it is no
convincing reason for me)?
Unfortunately I only have the German version and switching languages in
PS is not as easy as in GIMP. So if we want to do this somebody with
an English version is needed.

I agree with you.

Kind regards,
