Before I would go changing developer combinations in search of more contrast, I would try increasing development times. If you consistantly do not have enough contrast, your negs are underdeveloped, underexposed or both. A good Zone System type calibration should solve your problems. I use PMK as my standard developer (albeit with graded paper) and develop from N-4 through N+2. You should probably be aware, however, that pyro developers are most prized for the grain-reducing stain and their ability to hold detail in the dense areas of the negative. If you are trying for very high-contrast prints (lith effects, etc.) you will probably have to change developers. Regards, ;^D)(posted 8415 days ago)
