Still the same Nikon D300 and 18-200mm lens I have used for five years. I cleaned up some minor skin blemishes in Photoshop and I think the conversion was simply done in Camera Raw by checking the Convert to grayscale box. I don't think I worked on it much at all...when someone is this beautiful it makes your job easy
f13, 1/160th, 150mm, ISO 200
Here is the original unretouched
