Reuse Rodinal ?
View previous topic :: View next topic

Can I reuse the Rodinal developer I used for one roll?
If so, how does the developing times change?


Reply

If I remember correctly (it is years ago) it cannot be used again. Just found that also on wikipedia (but in german)

thanks.

But there is RODINAL SPECIAL, that can be reused (page 7)

(sorry, found only the german one...)

There is a discussion about that here:

Ah, so that is the difference with "special"! I always wondered.
Anyone has experience with special?

As far as I know they are total different stuff, the only connection is in the name. More than that I do not know, since I've never used Rodinal Special. I would not reuse Rodinal since it's common to use it at high dilutions and thus when used once it's almost surely depleted.

Cheers, Marty.

I think I'm in the super minority in that I don't love Rodinal simply because it is one use.
T-max may cost more but I still find it a better value.
Rodinal is difficult to dispose of for me (all are). My house is on a septic system and I refuse to use the toilet to dump developer.
I know the label says ok but, no way!

In Italy we have so called "Ecological Stations", where you can take these liquids to for disposal. I have a can where I put exhausted liquids in, when it is full I take it to the eco station.

Rodinal is not expensive, so I doubt I would consider reuse.

I'm on a septic system too. I have been pouring it down the drain with no ill efects......yet. I may store it and dispose elsewhere.


Reply

Even it it could be poured down the drain, I would certainly NOT do it
and also rather collect it and bring it then to an ordered disposal station (we have those here to). Simply for eceological reasons.

I like one-shot developers in the summer because then the ambient room temperature often reaches 25°C or more and the tap water isn't as cold as it could be -> a lot of bottles cooling in the sink -> angry wife. A one-shot developer leaves me with just the fixer and stop bath which is more manageable.

Apart from that, I've see no problem with either kind. Will try a bottle of Fomadon LQN I recently got to try out (some say it's intended as a paper developer and not for film), the first one-shot I'll try apart from Rodinal and the old recipe Foma R09 (1+40 dilutions instead of Rodinal's 1+50 and so on).

Single use , especially when the dilution ratio is 1/100 or 1/75 .... The developper energy is almost completely exhausted when you process a 36 exposures 35mm film .... Same thing with the Neofin "Blue". These developpers are excellent for very slow films , 25 to 50 iso.

You mean Foma(the producer) says that? Smile

You mean rodinal? Have you tried Tri-X pushed to ISO1600 and developed in Rodinal 1+100? nice combination for reportage;)

Nope, just some speculation on another forum I think (maybe a bit silly to keep that rumour going by re-posting it here) Wink Foma certainly labels it as a film developer, have not had time myself to use it yet but it will be the next one-shot developer I'll try out.

Ditto the high-dilution usage of Rodinal, it makes for a certain 'look'.

Yay, i switched Fomadon LQN(negative) and Fomatol(positive).. sorry, you´re right.

Ive tried it no.

1+50 rodinal used once, then immediately again - zero result.


Reply

It deteriorates pretty quickly when mixed, even at 1:25.

Once used 1:25 will almost develop matte papers~ if it's used immediately after the film. The murky, muddy results aren't really worth the effort.

To me, the original Rodinal system made a lot of sense on my highly varied schedules. No puttering around with replenishing powders etc, which ended up with a lot of good developer wasted in my experience.

SPAM! See the url tags at the end?

[quote="victorpatrick"]Yes, you can reuse Rodinal developer for multiple rolls of film. Rodinal is a highly concentrated developer that has a long shelf life and can be reused.

Tri-X developed this way worked very well for me, especially with Ilford's multigrade matte/pearl papers.

Loved it with tri-x at ASA/ISO 320 and 1:50.

Yes, it was aimed at home-developing where only a few plates were developed at a time (1890s)
Very practical, highly concentrated, not too sensitive to temperature and fast acting.

It fell out of love in the 70s, when grain was underrated but came back in the 90s.

I made a mistake recently and used 1:10 instead of 1:25 for AGFA APX100, luckily I realized the mistake before the 1st minute and made a quick calc in my head. Negs are salvageable.

Good for you. I sometimes (not often) am that quick on my toes...

In the 1980s I worked in a commercial lab and they reused Rodinal for a week. They used a liter already diluted to develop about 5 36 exp 135 films. They kept it in the refrigerator between work days. I was surprised since it was a single-use developer but everything was of sufficient commercial quality. Regards
