Ansel Adams is my hero. He mastered how to intermix the science of photography and the art of photography. I highly recommend reading his books and those about him.
In short, he perfected what he called “previsualization”. In other words, study the vista before you shoot the picture. Know in advance the scale of the picture. Should objects in shadow show texture? Should objects in bright sun show texture? What shade of gray do you want various objects to appear in the finished print? Based on your knowledge of how film reacts to light and how it develops, expose the film to reproduce your mind’s eye. Develop the film, using manipulative techniques to achieve the desired gray scale. Print the resulting negative using manipulative techniques to achieve a print on paper with the desired ambiance.
This is a tall order. Reading his books plus about 10 or 15 years of practice will allow you to achieve. You will be handicapped by the fact that things have changed since his books were written in the mid 1950’s. No harm, no foul -- reading and studying.
I say, don’t spin you wheels studying techniques that mainly apply to chemical based film, chemical based photo paper and the devices used to develop and print. Read to get a feel for what he accomplished and apply what you learn to equaling and perhaps raising above his accomplishments using modern mechanisms. This will be, to say the least, a long learning curve. Keep in mind, a journey of 1000 miles begins with a single step.
