do you reuse your chemicals ?

I am down to my last 20ml of rodinal, so I intend to develop 6 x 135 and 1 x 120 format rolls
and reuse the same soup over and over again. I am currently waiting for the last 135 rolls to
be fixed before I start on the 120 roll, in terms of timing, i am adding 30seconds to the development
time (at 30C :) ).

Do you reuse your chemicals, and how long do you keep them and how often do you reuse them for ?

thanks!

ps. in terms of fixer, i mix a 600ml of fixer solution (120-150ml of the rapid fixer+water) and use
for about 20 rolls. i start between 5mins to 10mins up to 10 rolls and then 20mins to the end of the
20 rolls.
 

i developed all 6 + 1 roll today in 2 hours, this is my personal record
with a 2-roll Peterson Tank. The last two rolls, despite increased agitation
and longer time, looked a bit low in contrast. Will investigate when I scan.
 

I think there's a formula to "refresh" the developer, like dump a percentage and top up with fresh developer. I developed 2 rolls of Trix @1600 using Rodinal as well, the negs look good.
 

I always use my developer as one shot after a previous incident with my film. Re-used dev for second roll, which turned out massively underdeveloped. Turns out that the developer had nearly expired, and re-using it tipped it over the useful life. Lost a roll of shots.

Can you buy R09 in Singapore? It's really easy to get in Australia. I'm moving from Aus to Sg in December, if you need any let me know. It costs me about $20 per bottle plus $20 flat rate shipping. Personally I prefer hc110.

I re-use my fixer though. Never throw away. If its getting weak I just pour a little more. I also re-use my stop bath when printing.

i am currently using ilford ilfosol 3 developer, and i never re-use it

fixer, im still using my first batch of ilford rapid fixer - must've done a dozen rolls over the last 6 months, and it still fixes fine after 5min. i think its time to dump now though!

Some developers have replenishers available, is that what you mean? I've seen Kodak replenishers but can't remember which developer. I only use liquid concentrate developers like hc110, rodinal and ilfosol.

Argh my experience with ilfosol is not very good, it expires after 3-6 months if your bottle is not completely air tight even I concentrate form. Be careful make sure you test once in a while with film leader.
 

20 a bottle is cheap if you handcarry it. i ordered mine from macodirect.de.

r09 aka rodinal is rarer than a hen's teeth here in singapore.
 

just now i developed one 35mm roll of tri-x with rodinal 1+50, after finish developing, the working solution come out like octopus ink :o
dun feel to reuse it for another roll:sweatsm:
 

oceanpriest,

mine turned from grey to very grey...and after the 6 rolls of 135 and
1 roll of 120, the liquid was quite disgusting...luckily, the solution still worked :)

from last roll,

the toning was added in and not stained by the liquid :)

One roll of 35mm uses about 3.5ml of rodinal, after that most of the power gets exhausted. I learnt this from experience, haha. So I figured that if you use 1:50 solution in a 600ml tank that would be about 30ml rodinal, you could develop about 10 rolls max if you reuse. The timing will get longer and longer with each batch so your consistency will be out the window though.
 

For developing, I reuse both stop bath and fixer, never reuse developer. For printing, I dump it all away after i'm done.
 

Actually I don't even use stop bath for film, only use that for paper.

Btw can we share fixer use for fixing film and paper?
 

okay....

yesterday i mixed a gallon of d-76 and
developed 6 rolls of fomapan 400. due to
the temperature here in asia, i used 30c
for dev, this comes at the expense of
grains and potentially uneven development.

one batch of 6 rolls, broken into 3 development
of 2 rolls each. the same chemical was reused twice
and i compensated by using 20% additional time.

I developed the first 2 rolls at 5mins 30sec. the next
two at 6mins and last 2 at 6mins 30secs. all except one
roll was shot using the same camera, the contaxt t with
aperture priority.

Overall, the first 2 was underdeveloped, contrast was a
little low. roll 3&4 yield the best negatives, the last 2 was
okay as well. contrast wan't scary.

for my next development, i will increase the dev time
to perhaps 6mins or 6mins 30seconds to start for the
first 2 rolls and perhaps increase it by 15 secs for the
subsequent rolls.

the images below are post processed so the issues
mentioned above can't really be seen PP. anyway,
here are the images, all captured this past week.
