Thank you everybody.
I was use three flash sources for front and one for background light. On front two wafers (140 and 100) and big sunlight with difuser. Wafers was on two Bowens generators (3000 and 2400 ws) maxed out and sunlight was on Bowens esprit 500 also maxed out. All front lights was very close to the subjects. You must difuse your light and get some midtones on unflashed Harman paper.
