From shoot of 11/19 with Kristie. The "contrast" refers to the rough stone wall vs model's smooth skin - although there's really not much of the wall to really provide contrast.

All editing done in Lightroom(2) with Nik Silver Efex plug-in. Skin softening done with Local Adjustment Brush with negative Clarity setting. B&W conversion and toning done with SE. Slight brightness and structure tweaks.
