I used and still do use the "sunny 16" with my 4x5. I guess the "easy" part is shooting a picture looking at the back of the camera to see if you got it right instead of sending the film off and waiting a week for the results. Oh and by the way it cost. With digital you have more choices/setting for different results where we used different films for different results. I can't tell you how many double exposures I did switching from one film type to another for different situations and not marking the film. I like film and just love that sound of the film advancing. In the past I have always been the last guy to embrace new technology. It's sad to say that now days as much as 75% of my photography is digital.
