Make Normals "brighter" I am currently looking for a way to make normals "brighter".

The reason is that I was looking for a method to combine two normal maps and found this question: How to Combine two Normal Maps?
I implemented all of the described techniques and two of them deliver the same result but the second one is a bit brighter. I wanted to make the first one look like this too.

First one:

Second one:


Thanks in advance!

EDIT: Actually it's the other way around. The second method seems to brighten the color.

EDIT: For clarification the first method is the one by redcapricorn / Secrop and the second one by Bithur.
I think it might appear brighter because Bithur divided with an HSV Value of 1.25 but I don't know how to enter anything beyond 1.
The Normalmap is not Normalized. Normalize your Normalmap to get correct results.
