Beyond The Zone System - Wonder Wheel with Factory Film Paper Data

[Mustafa Umut Sarac]

I know BTZS Wonder Wheel making is in the 1981 Book. I tried to read it and will try to read more. Its difficult.
I want to make a woder wheel with Fomapan 100 D76 Factory Data and I want to add this ilford multigade and multigrade developer 1+9 factory data. I have no access to densiometers , V700 scanners etc. Has anyone tried before ?

 

[John Wiegerink]

One thing I would do before I did anything when using Foma 100 film is to always think of it as a ISO 50 film and not ISO 100. Most everyone here that uses Foma 100 or Arista 100 rates it lower than ISO 100. I rate it at ISO 50 myself and never try to over-develop it.

At least here in the U.S, in 1981 Foma was uncommon, by the second edition Davis was no longer using the Wonder Wheel his methodology has shifted to use of densiometer so it is unlikely, still possible, that someone has the data you are looking for.. Second, Davis wrote that BTZS was developed for sheet film, although you can use the testing to find the effective film speed you can obtain the same ISO for any given roll film by shooting a ring around. As noted above looking at the Foma data sheet for Foma 100 the only developer that comes close to ISO 100 is ILford Microphen, most developers are a full stop slower around 50 to even 25. Below is the link to the View Camera Store who sells BTZS tuitorals and will test flm, just not 35mm, only sheet film. You can contact Fred to see if he has tested Foma. Seems his current film of choise for BTZS is Delta 100.

I have just filled the contact form. If he can share delta 100 d76 test results , that would be great.

I hope he can be of assistance, just remember that what ever data he has will not apply to your situation. As you are a 35mm shooter and he shoots sheet film your meter and shutter may not match.

I think we can select one photo in 35mm film and develop the roll with specific to this photo and discard others. This makes me sheet film shooter when using 35mm camera.

 

[Paul Howell]

I have loaded 35mm from bulk in rolls of 4 or 5 exposures, then develop for highlights, from +2 to _2. Currently I use a ring around to find a E.I for a given film and developer, use spot meter on my Minolta A mount cameras and meter for zone III then develop for Zone VII and adjust with VC paper. If you can get the data for Delta 100 then you need a decent incident meter.

Ah Mustafa, don’t we miss our old friend PE. I was so glad you got to know him.

The Wonder Wheel is a marvel of imagineering and extends the Zone System 10 grays into many slices of grays in a fan shape.

You need the skill to slice a graphic arts platemaking mask into wedges with an X-Acto knife. Then you watch a clock and at specified intervals you fold one more sliver over as you make what amounts to a contact print of a broom.

The result is a grayscale that you slide in a sleeve which stretches and expands according to the subject luminance range when you develop the film at the recommended times.

Truly a wonder.

Haven’t done one, but I could. Just need a sheet of goldenrod.

Hi Bill , Yes I miss very much PE. He was a wonderful man. I will please from you to draw wonder wheel on a sketch note book and share. I am not understanding the concept and descriptions. If you can add paper and film curves , black to white going tones , it should be complete. Thank you Bill.
