Translated it is:
Now double the just adjusted plain, blend out the one one the top, and use following effects:
(I'm gonna skip thise, they're already in english..)
Now connect (merge) the middle one and the lower one (layers) to one. Press Strg+U
Put Saturation to 0 and press ok. Now again Strg+ U
Now make a check at colorize and put following settings in:
(I'll skip those too, they're in english again.)
Now again ok..
Turn the upper plain to visible and the plainmode to soft light and the opacity to 60%
Now connect the the two plains.
Hope, that it helps you
