Lovely model and mono conversion, Richard
Some really nice details.
I'm not a portrait shooter but the only thing that spoils this shot, for me anyway, is that I'd have liked to see more space at the top.
Other portrait shooters will probably disagree
I can definitely see your point. I used the NIK Software Silver Effects Pro II to convert the image and I also used that software to provide the borders. I hadn't noticed it before but the Silver Effects Pro II places a border WITHIN the image not OUTSIDE the borders of the original image. I didn't notice that it had infringed on my original crop. This is the way I cropped the image before inserting the borders...
