I studied under Victoria Ryan who taught me the wonderful technique of Ansel Adams called the "Zone System ".

The Zone System is a method for controlling the black-and-white photographic process.  Conceived by Ansel Adams and Fred Archer, it applies the principles of sensitometry (the measurement of the effect of light on light-sensitive materials) to organize the many decisions that go into exposing, developing, and printing a negative. Briefly, it works this way: You make exposure readings of the luminances (the lightness or the darkness) of important elements to be in a final print. Then you expose and develop the film to produce a negative that can, in fact, produce such a print.The Zone System allows you to visualize how the tones in any scene will look in a print and to choose either a literal recording or a departure from reality.

Ansel Adams remains the acknowledged master of the grand landscape. His great vista are mythic images that reinforce our romantic ideals of nature. Adams was a superb technician who controlled his medium completely to amplify and bring to life the tonalities in an image. No book reproduction can convey the range of tones in the original print, from the glowing brilliance of the clouds and crosses to the subtle detail in the dark shadows. The photograph is everything that we imagine such a scene might look like in reality, and for many of us it will forever serve as a substitute for the actual experience of being there to see it ourselves.

Victoria also taught me the sepia technique of Hypo-alum toning .

The Hypo-alum Sepia toner produces brown to reddish-brown tones on almost any print. The actual hue that you will obtain depends upon the toning time and the temperature used.

The most basic hypo-alum toner consists of two constituents- hypo and alum. However such simple solutions do have a tendency to attack and dissolve some of the image-forming silver in the print, notably in the highlights. By adding silver nitrate and potassium iodide the ripening time is decrease and the potassium iodide give a toning solution that yields warmer tones.

A split tone effect with deep blue shadows and brown highlights is obtained by adding sulfur.

Together it will give you a dual toning effects of warm and cold tone.
 

I am true "natural" photographer in that I process my films, print and toned to give the true reflection of the soul of my subject mixed with mine.
