A book is being read called, ZONE SYSTEM MANUAL, How to Previsualize Your Pictures, by MINOR WHITE, New Revised Edition, Fourth Printing 1972.
The first lesson has been done. It is about experiencing zones. One subject was photographed with three settings. It was bracketed one stop above and one stop below the middle gray setting made with a reflected light meter. In this case that would be the Pentax TTL meter.
Differences between the values of the same objects in different pictures is one zone each.
More film was purchased. Fast film like this HP5+ is too fast for the experiments. Film speed of 50-200 is to be used. I bought some HP4 which is 125. That film is better for my camera anyway because of the speeds on the dial: 30, 60, 125, 250, 500, 1000.
The next lesson calls for lots of films to be exposed and developed differently. I do not want to shoot an entire roll just to develop one thing so I think I may cut rolls apart. Two rolls will be exposed to the same thing then cut into 2 parts in the darkroom. Each part may then be developed differently. Actually 4 parts in all. The FP4 will be pushed one and two stops and 2 parts will be exposed normally and one stop over. I’ll shoot at 50 and push to 125 and 200.
There is another type of light meter to use. It is a Spot Meter. I have one but have not used it. Yet. It is used to determine the difference between the lightest and darkest parts of a picture. These pictures have near white, lots of grays, and near black in them. The Spot Meter can measure them and give you numbers to work with.
Contrast is the idea and development times with exposure changes controls it.
When I went to the gym, I noticed white signs, black windows in the shade, and lots of gray pavement….
