Description Ultra-High-Resolution Black&White Film The sharpest, most fine grained and highest resolving image recording system in the world. Perfectly matched for each other: ADOX CMS 20 II film plus ADOTECH developer. This film cannot be developed in regular developers! Update: We have received very nice 35mm CMS 20 II b&wslidesprocessed at Studio13 in Stuttgart in theScala Reversal-Process. There are some details missing in the shadows and the contrast is on the upper side but they look OK and the resolution is stunning in the projection. Thus we recomend this process for low contrast scenes or active contrast control during the take e.g. with the use of areflectorin portrait photography. The ISO recomendation is 16/13.
