So the question was "Can you produce a winning B&W photo from a RAW image using just Aperture, or do you really need to invest in something like Nik’s Silver Efex Pro?"
I believe with the right image you can. I hope this image is the "right image" taken on a trip to Lisbon Portugal. I played around in Aperture and came up with this. I went slightly overboard on purpose with the Definition tool and used an Apple preset to convert to B&W.
All comments will be gratefully received as I am learning all the time and soak up feedback.
