Very fine B&W portraits. Got me wondering about the lens, so I looked at the exifs. Looks like you kept zooming in more, true? B.D. stresses getting close with a wide lens, but I love the bokah with longer focal lengths that you are getting in the portrait of the woman.
The first one looks like it is probably a natural for my favorite B&W conversion technique to get a more dramatic sky. Have you tried this? You may need to use a pretty aggressive surface blur on the red layer.
I'll study and try your method. These (B&W) were done with Silver Efex Pro, but I sometimes do B&W in CNX2 myself by blending.
I'm thinking #1 might be a textbook case for layering red over green in darken mode. I'm trying to pull together examples for a B&W workflow tutorial. Would you like to let me see what I can do with it starting from raw (or color jpeg, for that matter.)
