I have gained a very basic understanding of view camera focus techniques by read ing Steve Simmons "Using the View Camera" and similar basic descriptions (as wel l as practicing). I'd like to get a more in depth understanding of degrees and types of movements for practical field application. I've found the on-line Merk linger articles somewhat helpful, but more theory and mathematics than I can dig est without much coffee and concetration. I'm wondering whether his book "Focus ing the View Camera" is a more helpful practical reference, or if there would be other recommended books to help out. Thanks for the advice.
