Phil Davis in conjunction with the View Camera store is organizing a workshop for the BTZS method to be held in July in Flagstaff, AZ. As many here know, I had to eat some crow and admit that once the testing is done the BTZS is a wonderful method to get correct exposures. While I was corresponding with Phil, he mentioned his traveling days might be over. I don't know if he will continue to teach the system in his home town, but I think for those living on the west coast this might be the last time to learn and experience the system straight from the creator. Phil is a wonderful person and a very patient instructor, if you wish to learn how to make the best possible negatives don't miss this opportunity. Those interested can contact the View Camera Store at http://www.viewcamerastore.com Or Phil Davis at: http://www.btzs.org And no. I am not getting a kickback, Phil has been very helpfull and patient with my questions so I am trying to return the favor.
