I received the book two years ago and struggled to get through it and gave up. This year, with a really boring job to help me, I started reading it again and finally got it. I have read it several times now..There are many charts and graphs thrown at you in the beginning which may turn most people off. I never did get into manually plotting the results. I also went through every post on Phil's BTZS forum looking for more information.
I ordered the Step tablet, film test and plotter software from Fred at the View Camera Store to get me started. I also bought a used X-Rite 810.
I am the point now of testing some papers (should have done that first) and will try the system in the field as soon as I stop working 7 days a week at my job...
Nice to hear from others on this subject.
Regards,
John
