Best 4x5 Developing Tank

[Dwarak Calayampundi]

Hi I am opting for the Paterson solution as I already have a system 4 tank I am at the moment using the taco method to develop the 4x5 sheets I am new to developing and use rodinal with concentration of 1:100 and stand development got very good results so far. Want to know if I develop 3 sheets using the system 4 tank how much rodinal will I have to use to process 3 sheets.

The minimum amount of Rodinal is 10ml per 8x10 sheet* regardless of dilution.

That requirement may prevent you from using a 1+100 dilution, depending on tank capacity.

*Note: An 8x10 sheet means one sheet of film that size, or any combination of film that can be proofed
on a single sheet of 8x10 paper, e.g. four 4x5 sheets, one 35mm 36-exposure roll, one 120 roll, etc.

Leigh,

I did not know that. Tonight I developed 2 sheets of double-sided X-Ray 8x10 with 10 ml Rodinal at 1/100. I could not see a difference in the two sheets.

I may be pushing the limit.

I will stop being so parsimonious.

Hi Randy,

Yep. It's right on the datasheet, although kinda convoluted. It says a 500ml bottle will process 50 rolls of film.

I've followed that guidance for over 50 years, with consistently excellent results.
I was introduced to it a few years after I started shooting, and it's been my standard developer every since.

Note that Rodinal is meant for slow films. Obviously, X-ray film qualifies as slow.
Results with fast films (400 and above) may differ.

Thanks for the advice I do not process in large quantities and the maximum would prob do 3 4x5 sheets with rodinal. I got my self one of the new Paterson tanks looking forward to using it.

Yes, I did not like 35 mm with Rodinal, but 10 minutes at 1/100 seems good, with LF.

Sergei, is doing good research with time.

I am trying to standardize with Rodinal, it is cheap, concentrated and one shot.

but where do you buy Rodinal now
it no longer seems to be available in Canada
up until about a year ago the same formula was being sold under the name "Blazinal"
but that supplier is no longer distributing it according to several stores in Toronto

Rodinal is available under different names, including R09.
There's some problem with the trademarked name Rodinal.
I think some company bought the name, but they don't make the product???

I buy it as R09 from Freestyle.

As far as I know Rodinal is a trademark of Agfa who has long stopped producing it. There are several alternatives that mimick the composition, but I guess are not exactly equal albeit producing very similar results. In Europe R09 is the usual alternative and is commonly available - it is the one I use.
