Sigma Photo Pro 5.5 now offers dedicated Monochrome processing for X3 raw files from the original SD1 and all cameras in the Merrill Generation, the SD1 Merrill, the DP2 Merrill, and the new DP3 Merrill.
The X3 processing has completely re-engineered for exceptional monochrome results, with great control over tonal range, contrast, subtle gradations, and a simply beautiful film grain option for expressive creative control.
In this demonstration, I work up three images captured with the Sigma SD1. One is a very low contrast image, the second a very high contrast image, and the third, an infrared shot through an IR-passing filter with the Infrared cutting filter in the SD1 removed.
