I have an 810 too. You can read the values and put them in the GRAY_CURVE= parameter.
I find it quite useless though. I use the build gray curve tool to adjust the curve in a rough way
Then I use charthrob to refine the midtones.
Much more convenient!
Have fun!

Hi folks,
I was wondering if there are any tutorials on how to use a densitometer to create correction curves for digital negatives. I am Mac based and have an xrite 810 to use. Are there conversion tables to convert my 810 readings to % readings. For instance, how do I know what 20% gray is supposed to be with my densitometer readings? Do I even have to convert the densitometer reading to % or can I enter the densitometer readings directly into the curve line n the qtr profile? I have been using my scanner to read the %densities but want to see if mt densitometer is more accurate, am I being foolish to try this instead of just using the scanner? Thanks for any tips anyone could offer!
