Strange Harmony behavior?

[Tarun Chopra]

Hi,

This is kind of a strange observation while using Harmony, details are given below:

a) Make a target curve (single curve) put 50% = 70% ie a 20% dot gain
b) Make a current curve (single curve) put 50% = 60% ie a 10% dot gain

When I create a derived calibration curve the curve dips the most at 70% and not 50% where I have modified the values in target and current curves?

Any suggestion or observations on this aspect.

Thanks

ummm...does it look like the attached? if so, then you're all set. - Roger

Hi,

Yes you would get a better understanding if you change the option to view -> graph type -> dot gain.

I am seeing a negative dip because my current values are at 20% gain and target values are at 10% gain so the correction is a dip of 10% but at 70%??? what you have done is correct but is opposite to what I have done, in your case also we see a top value at 70%... any guess on why Harmony does it this way.

Thanks
