Changing the mindset from averaged variable contrast measurement to split printing was a bit of a challenge but after using and testing for a short time I have discovered that it is actually easier. Where Mark and I have disagreed in the past has been the use of a Beseler Analyzer to determine correct exposure. Dan Post has been most gracious with his time and knowledge in programming and teaching several in our photo group the application. When I returned from my visit with Mark and my new learned skill I immediately discussed split printing with our group. Dan loves challenges and immediately began the study of applying the Beseler analyzer to split printing application. Frankly it doesn't matter to me how one comes to the correct print exposure but when one can save time and money is part of the result I get excited. Learning to read test strips is something that Mark is extremely good at. I am not. He can "nail" a correct exposure on 1 to 2 prints. It had been taking me 5-6. WIth the use of the analyzer I can consistently get it on the second print, occasionally on the first. When using FP 11x14 paper at 75 cents to a buck a sheet it becomes important to reduce the waste. The one particular area that I see the advantage of split printing is in the highlights. It dramatically reduces the need for burning in. The Aristo Variable Contrast head is incredible. I don't think that I could go back to traditional printing. Again, my sincere appreciation to my friend Mark Rabiner. He is one of the most generous people that I have ever known with his time and knowledge. Bob Bedwell
