I want to try the linearize and my densitometer has visual as well as rgb channels to choose from. One thing I'm not fully grasping is how to get the known values for the densitometer readings in order to create the curve. In percent readings it's easy for me to have a say known 5% patch that reads as 12% with a scanner and eye dropper tool so I know how to adjust the curve but I can't wrap my head around how to figure out what a known densitometer reading should be so that when I take a reading of my contact wedge that needs to be adjusted I'll know how to proceed. Is there a conversion chart or formula that you use to get known density readings? I must be missing some detail to the process? Is it possible to explain how you arrive at your target density vs actual density figures.
Thanks
Erik
