25. After each etching step we have taken images under "light" (set point ≈ 95%) and under "moderate" tapping conditions (set point ≈ 85%). The observed dependence of the phase contrast on the set point value is consistent with respective experiments on SBS films prior to etching as well as on. films of PS/PB homopolymer blends. Most important for this work, phase images taken under light and moderate tapping conditions give practically identical results after the normalization procedure described below is applied. However, images taken under light tapping conditions suffer less from problems due to take-up of polymeric material and lead to "better micrographs". Therefore, we have chosen the images taken under light tapping conditions for display in Figure 3 and for 3D reconstruction.
