I have to process a 120 roll of new Tmax 100 in Rodinal.
Agfa says 5'30'' at 20°C.
My problem is that since I'm Using distilled water, I have to work at
24°.  You can't imagine how much Italy is hot now.

O.k I"m very familiar with shooting 35mm film, ( I do B&W) developing,
making prints in my darkroom so I made a plunge and bought a Rolleiflex
camera medium format (dated 1955) and I got it today and the  ASA only goes
up to 200 speed and I already ordered some 120 Ilford film at a ...

I am planning to make small B&W prints until I find my desired print and
than print it on a bigger scale. Is there a formula I can convert the
printing time for the new scale? It sounds logical to me that if I double
the height of the enlarger head I should double the exposure time. ...

O.K. your thinking shouldn't I be posting this question to an
Astronomy or Science group somewhere?!
Well I have a reason why I'm coming to you photographic experts on
this group with a dark room simulation request. Here goes.

Anyone know why Luminos' website does not seem to exist any more?  I've
tried getting some product info and emailing them.  The site never comes up
(luminos.com).
Thanks for any help anyone can provide,

Processed my first couple of rolls of 400TX  (320 iso) according to Kodak's
rotary instructions and the neg's are thinner than I would like them. By my eye
it will take about 10 - 15% more time.  What's the general accord on
development timing of this new film.

I develop TRI-X in D76.  I rate the film at about 280.  I would like to reduce
the contrast but maintain detail in the negative.  I have attempted to
accomplish this by deluting the developer and extending the devilopement time.
Is apporach sound and I should just contiune further ...

I have used only RC paper so far and have been using FX-24 for both
film and paper.
I now have fiber paper(Ilford Multigrade warmtone as well as normal
tone) and want to do as much "archival processing" as possible.

I recently acquired a number of 5x7 and 8x10 glass plate film holders.
I've searched the internet in order to get more info but to no avail.
What I'd like to know is what kind of glass I need to get (i.e.. will
thin window  glass do?).  One of the holders had a glass plate in it ...

I live in the St. Louis, Missouri, area, and have a homemade (plywood
sealed with resin) darkroom sink that I need to get out of my garage.
This belonged to my ex -- he didn't want to take it when he moved out
last year.

It can be anything

On the 1200 Durst Enlarger column there is a scale along with the enlarger
height scale (I believe) in inches and in meters. This particular scale has
4 divisions for 50mm., 80mm., 105mm. and 150mm. enlarging lenses and has
sequential numbers not necessarily starting from 1 within ...

Is there a webpage that summarizes the characteristics of various
developers?
I googled but didn't find much.

I found myself a little tongue tied and embarassed the other day
trying to explain the photomechanical process in full from how the
latent image is formed, to what the developer acually does, fixer,
etc. Whats a good book for a full on explaination that I can reherse
