When I bought a darkroom outfit a while ago, one of the nice surprises in it was a Kodak Darkroom Dataguide. It's full of useful info, including the same developing wheel. That thing's fast and convenient, and I use it to adjust for temperature changes as we go through the seasons. If you ever run across one of these little books, grab it.

To the OP: welcome to APUG and thanks for your post.

The Kodak Darkroom Dataguides are an excellent example of what you suggest.

But if you cannot find one, your link could be quite useful.

I have use the wheel in the Kodak Darkroom Dataguide works great if have one and using all Kodak.
The other is last I new Kodak stop printing it 25 years ago.

You can use the Kodak wheel for all films.

Use other sources (e.g. Ilford website, Massive Developing Chart) to determine a "developing number" for 68F/20C developing of your film and developer combination. You can then use the wheel for that combination.

It is true that they haven't been published recently. But there are a lot of used ones out there, and it really doesn't matter which vintage you use.

The trick is in determining the correct developing number.

I have a Kodak Darkroom Dataguide. I've been struggling with transposing some MDG times. This is very helpful.

I use Kodak's all the time.
Most of my notes on development say things like Plus X Pan process normal d-76 1:1 low contraast lighting DN 43, for example.
The DN 43 gives a setting on the dial that gives a range of tiem and temperatures.

I try to stay close ish to 20C, but am not fanatic about it with this tool.

I use a 40 year old Kodak data guide too - not for the times they give, but to adjust between temp changes, etc. I even have the index number from the guide in some of my records.
The enlarging guide is handy too, just for approximating exposure adjustment between enlarging ratios.

With regards to time/temperature charts/wheels. In my darkroom I have a little chart that shows the development time for temperatures 5 degrees above and below 68F/20C for FP4 in D76 at 1:1. I don't process outside those limits.

Da... Ive printed out the Development wheel, but am I correct, that is worthless, without the guide to give you the ''DEVELOPING NUMBER'" of that particular film?
As exampled on its page one, it shows developing Arista.edu Ultra B&W ISO 400.. and that must be referenced in the guide as #38 ... ???

Hmmm..

I suppose it has its use, without the guide, using the times you have come up with for your own situation, agitation, type of water ect, or going to Digital Truth, and set developing time, and then you can mark that 'DEVELOPING NUMBER' .. in your notes for that film, and then have an easy read, for the changes in temperature of the development, and / o, lower or raise the contrast.

Have I grokked this out correctly... ;-)

I use the Massive Developing Chart app, it has a temp/time converter built in.

My 1996 Kodak Darkroom Dataguide has no wheel. There's a chart...and not much of one. *sigh*
