On Chase Jarvis’ blog, guest poster Scott does a nice walkthrough of converting a photo from color to black and white in Aperture 3 and making the point that the finished product is every bit as good as in Photoshop.

The above file on the left was processed entirely in Aperture. The above file on the right is the Photoshop version that we discussed before the holidays. One can certainly nitpick to find details that are different between the two, I know I did, but that would be missing the point.

Speaking of the point, let me get to it. These two images were processed with different RAW algorithms, retouched, adjusted, smooth, and sharpened with different tools with different abilities and nuances. People will rant and rave ad nauseum online about the differences between software offerings. Yet despite all of the obvious discrepancies between the Aperture and Photoshop methods, the net result is very much the same. The vision is important, the method is not. Join me after the jump to learn more.
