Where can I get a set of exposure factores for converting exposure
times with grade 2 contrast to another grade. The enlarger is a Durst M670 (I think?) Chris.... |

How are you adjusting contrast? I've just started printing myself so am on a step learning curve. I first did a few test strips (with all colours set to 0) to get the correct exposure. I have just found out that you can not just adjust magenta for example to increase contrast to grade 3 without having to redo an exposure test. Someone old me they was an easier way of doing it by using a factor with the exposure time. This is what I would like to find out about Chris.... |
