    Last question...I hope

    Well, so far, this is the last question I have:

    If the new paper speed is, let's say, 125 and the reference paper speed is 200, the correction figure to input is 2 1/3 steps by 4 equals 8. This 8 is a negative or a positive value?

    Thanks again and again and ...
    Alfonso

    I've got a Kaiser enlarger and I find the default values in the Analyser Pro to be correct for Ilford MGIV RC. Try the default settings with a negative that you know well. Make sure that it is well exposed and has a full range of tones. Compare the results you get with the analyser with your old prints.

    I did this with one of my favourite negatives when I first got the analyser and found that the analyser recommended printing half a grade harder which produced an even better print!

    It's a positive value because the new paper speed is a smaller number than the reference, indicating that the new paper is slower and therefore requires more exposure.
