I have been a professional retoucher for over twenty years. My approach is Do No Harm. The most correct approach to the picture. At the same time, the work can be very radical - ironing clothes, glossy makeup, a significant change in the background. But no more than the task requires. Keeping the individuality of the photographer and model.
Since I live and work in Israel the order "before-after" on the illustrations is "right-to-left")
