Gradation/tonal curve optimizing/multigrade


Thousands of samples later, we are slowly approaching our goal. The image tone is so close to the old PW that we have difficulties seeing the difference again which we thought we had seen yesterday. The contrast curve and multigrade range need to be touched up a bit more. The upper row shows our comparison prints on MCC. The difference in image tone can be seen on the computer screen already.
Developed in ADOTOL WA
We will continue after the summer break.
