The New Zone
System Manual is the most extensive single book on the Zone System to date. It
shows how to bring all the variables of the photographic process under control. The
New Zone System Manual teaches the individual how to visualize the image before
exposing the photograph. It applies to all kinds of photographycreative,
manipulative, multiple-image and multiple-exposure.
Minor White…Richard Zakia…Peter Lorenz…three experienced teachers and photographers combine years of training and experience to create this important book. Their material is on method and techniqueand their approach is understandable for anyone seriously exploring black & white photography. The New Zone System Manual features a sensitometry for working photographers that can lead to a deeper understanding of the nature of photography. For amateurs and professionals, this method of image control can be applied for consistent fine quality in straight photography or experimental photography. Any photographer who knows the essentials of exposure meter use, developing, and printing can master the Zone System. | |

Physical placing of the pots
This CDS meter from Weston Inc, Newark gained some popularity indeed but....it needs batteries. This is a problem that is hard to overcome nowadays. The model needed Mercury PX 14 or two Px13 batteries for powersupply. As Mercury batteries are no longer available due to environmental restrictions, we need a replacement.The voltage needed is exactly 2,7 volt(very finnicky). The replacement batteries are 3 Volt and will misinterprete the readings. So pamper the batteries you still have...maybe later we will have a solution to convert the circuit to 3 volts.

Scheme of meter
Above you can see the 5 pots which will regulate the High and Low readings. It is not possible to adjust for the 3volts from here.
On the left you will see the scheme and what function each pot has. In case you need to readjust your meter, follow the instructions given below the diagram. Source: Conrad Hoffman Canandaigua, NY I've adjusted the Ranger 9 by comparing the readings against a known good SLR. Use a lamp with a dimmer switch to get to the high and low positions on each scale. I'm down to my last mercury battery. Can you still get them where you are? There were some mercury batteries sold using a different formula that didn't produce 1.35 VDC. Avoid those. I haven't yet figured out the best way to incorporate a regulator for use with akalines, but that day is coming! Print or save this WorkSheet |

:::::: Ranger 9 - 2 versions :::::: |
On the left 2 versions of the Weston Ranger 9.Both meters are fully operational. Note only one scale is equipped with the EV Window. The Ranger with the Zone scale was adapted for the modern batteries Varta 625 (3Volt), the other one is still operating on the illegal, now discontinued Mercury type PX 14 (2.7V) Lucky me, I've got spare batteries.(they will last, thanks to their long shelf-life.) Battery is shown next to the original Invercone for incident light readings. This is an also hard to come by item. |

:::::: Hasselblad & Ranger Zone VI :::::: |
Not exactly the same year of birth, but a super strong couple...
The Zone scale proved its value over and over again.Also, it is very easy to change the dials if we want to use the EV values instead. Hasselblad C lenses used to have EV numbers cross coupled to shutter and aperture combinations. |

:::::: Weston Inc, Newark :::::: |
|
Only 5 years before the demise of Weston Inc in 1974, Weston Inc developed and marketed their only CDS meter. In the battle for the grace of the customer, Weston tried to compete with the other Exposure Meter brands who went CDS much earlier. The meter became quite popular but could not change the future....! Unfortunately the Weston factory in Newark was shut down in 1974. Most of Weston Inc. was bought by a conglomerate Schlummberger.(Aero Space)
On this occasion Ansel Adams said that many Photographers would regret the demise for many, many years to come...!
