Sigma vs. Nerd (Part 2: The BW Merrill)

After Part 1's discussion of the theoretical advantages of Sigma's Foveon sensor for BW photography, this next installment looks at the BW process in detail, making it even nerdier than Part 1. The article includes a discussion of the tonal differences between BW photos taken with Sigma cameras vs. BW photos converted from color images taken with "traditional" digital cameras. It then segues into an examination of the BW workflow required by Sigma, including both the advantages and disadvantages of the process, plus my recommendations for improving both the process and the cameras.
