My wife purchased a copy of Nik Software's Silver Efex Pro for Christmas. I decided to do little comparison of the B&W Conversion tool in Apple Aperture vs. Silver Efex Pro. Below are the photo's in color, Aperture conversion and SFX conversion.
Original Color Photo
B&W Conversion using Apple Aperture
B&W Conversion using Silver Efex Pro
These conversion were done using the default setting of both programs. I have to say that the default from Silver Efex Pro has much better definition and contrast than Aperture.
I will be playing with this software alot in the days to come and will post more thoughts as I complete more conversions.
Happy Holidays!
