Here are three pictures printed with the new zone vi enlarger with variable contrast head showing the differences in contrast possible.  All prints were made with the same exposure time, apeture and on the same paper with identical development.  I set the soft contrast setting at H and then shifted the hard contrast setting.  The bottom print was made using a setting of 'HB', the middle with 'HC', and the top image 'HE'.  As Ansel Adams liked to say, "The negative is the score, the print is the performance."  The images at the top are details of the bottom right corner of the image showing the impact in the darkest part of the print.  As the hard contrast is increased the shadow detail is lost
