During the initial run of the tool (Photoshop script) on the calibrated target, the script asks for the "white", "middle gray" and "black" steps along with their LAB values. The target I am using identifies the density of each patch - i.e. I know the density values of these are 0.08. 0.75 and 2.04 respectively. How do I convert these values to LAB for entry into the tool?
Thanks
