Good Working Method?

Hi:

I just wanted to get some opinions on a planned working method I have.

I just switched from Large Format to 120; I've also switched to a much smaller living area.

I've decided to use T-Max 100 as my primary film; with T-Max Developer (not RS), and Kodak Rapid Fix (to harden or not to harden, I've never quite determined which is best).

This will be my first time using T-Max Developer and many years since using a small tank (I'm use to 1/2 gallon tanks or tray processing).

In order to avoid excess mixing and to save storage space; I plan to mix the Developer and Fixer in gallon quantities and keep the working solutions in gallon containers (there is, of course, no other practical way to mix less Kodak Rapid Fix, but T-Max developer could be mixed each time from concentrate).

I plan to use the developer in a 500ml tank, returning the used developer to the gallon jug after each processing session (same with the fixer); discarding the gallon of developer after the recommended 48 rolls have been processed (or two months, which ever comes first).

Is this a reasonable way to proceed; are there any detrimental effects to returning used T-Max developer to a gallon container after using a partial quantity (500ml)?

Is it a good idea to use a hardener in the fixer with 120 film?

Thanks for taking the time to look this over; and for any thoughts or suggestions.

One. Personally I would choose to do one shot development with just about anything vs a non-replenished developer for better consistency with low volume processing. What you have specified is not even a replenished situation and you also did not specify a dilution. I personally believe if you try to use strait TMAX or even the lower dilutions of TMAX you will have a hell of a time controlling TMX from a consistency standpoint - it is a very responsive film and it is probably a good idea to use a slower working developer one shot for slightly longer development times so that a small timing error is not so influential.

Personally I like Pyrocat HD with TMX if you want something a little more TMAX/D76'y XTOL 1+2 or 1+3 would be a great choice - even Rodinal 1+50 or 1+100 would be a good choice.

Forget the hardener.

Of course the fixer can be reused - Just pay attention to the capacity recommendations.

I prefer myself a water stop bath and an alkaline rapid fix like TF4 or TF5.

I'm not sure why you think that Kodak Rapid Fix cannot be mixed in less than one gallon amounts. I have certainly done so in the past. I have never used the hardener - with your choice of film (or any other Kodak, Ilford or Fuji B&W film for that matter) it is not necessary.

As for the developer, I would recommend either one shot use with any of a number of developers (I use HC110) or, based on what I see posted here, regularly replenished, using XTol.

Good Evening, John,

I agree with RB that mixing T-Max Developer directly from concentrate immediately before use is the only way to go (1:7 for 10 minutes is my standard for T-100, varied somewhat depending on the contrast desired). The concentrate keeps well, and the bottle takes up less storage space than a gallon jug.

clearing time

t-max dev designed for non-replenished systems
use with roll film only
dilute 1:4

kodak only offers hardening fixers for film
their only non-hardening fixer is for processing rc paper in continuous roller-transport processors

if you don't want hardener, use Ilford Rapid Fixer


as a side note: some films recommend hardener, such as ADOX CHS

Please put used films back into these containers to avoid penetration of light.
Always keep your baths constant at 20oC when processing films out of the CHS range.
Old fashioned films will show effects like shrinkle grain when processed faulty. Many modern films are to a high degree resitant to this.
Please prewash sheetfilms to evenly dissolve the supercoating to avoid developer-streaks.
Please handle the wet emulsion with extreme care. It is softer than the emulsion of modern films. If necessary please add a hardening bath (either put some hardener in the stop bath/fixer or dilute 5ml of hardener to 1 Liter of water and pre-harden the sheetfilms before putting them in the tray. Please readjust your developing time after pre-hardening.

Thanks for the help.

I may rethink the developer I will use. As a note: the dilution I was planning for the TMax Dev was 1:4; also, for clarification, I just noted that I thought it was impractical, not impossible, to mix less than a gallon of Kodak Rapid Fix (especially if the hardener is included) - at least in the case of a "closet darkroom".
I should also note that I was working with the assumption that T-Max developer would be the best match for T-Max film, but maybe it's not best suited to my type of usage.

I liked Xtol quite a bit for sheet films and may go with that (as was suggested). Rodinal, too, is a great developer (but I think I prefer using Xtol). I've never tried the Pyro type developers (although I would like to trying working with them some day). Or maybe I'll go one shot with the T-Max (a 1:7 dilution would be fairly economical).
So, I will put some thought more thought into it.

Thanks again.

D-76 stock or 1:1 your choice
easy to work with

I usually use 1:1 to lengthen the dev times to make for less chance of error
(forgetting agitation for a minute or two) having an impact on results
unless the times are over 15 minutes, then it't time to go to stock and/or 75f

I guess you really can't go wrong with D-76 (plus it's good for such a wide range of films and dilutions).

I've found that using empty 2 liter soda bottles work quite well. The plastic doesn't react with the chemicals and the cap seals real well keeping out the oxygen. I've used mt clear as well as green colored bottles. And they store quite easily in a cabinet under the sink in a bathroom I use for film developing. The empty bottles stack real nicely on side for future use and I keep those in the basement. I also cut the small strip of plastic that remains after removing the cap as I don't want stuff trapped between that piece and the bottle. I take the label off as well.

Hope this method of storage may help you. The bottles take up little room.

My $0.02. Unless you have a huge volume of film you plan on processing, I would one-shot your chemistry. Takes up WAY less space. 'Course, I'm operating within about 23 square feet. Talk about economy.

Thanks again for the further posts.

I appreciate the storage tips (plus the soda bottles could be discarded and replaced easily enough when necessary).

Also, I am leaning toward one shot developing - I think it does make the most sense when doing a small volume of processing.

I appreciate all the advice - and I think it will help me improve my system greatly (I'm even giving a bit of thought of going to FP4+ or Delta as a main film, and using one of the Ilford developers in one shot).

I'm working slowly and, considering as much as possible - as I want to try to set it up right the first time.

Get Serious!

I got serious about saving space; single tray processing,
one-shot chemistry, AND all chemistry Home Brew.
Nothing left but the Wide Open Spaces.

For good milage the chemistry is used at more than
the usual dilution. Dan
