TMAX100 + TMAX (non RS)

[Sean Galbraith]

Learned how to develop at home today for the first time. TMAX100 4x5 sheet film. In my eagerness to go out and get the supplies I would need, I got TMAX developer for roll film.

So... Can I use this stuff even though I'm not doing rolls?

Sean,
You can use TMAX developer for sheet film, however, you may get what's called dicrhoic fog, a brownish metallic 'stain' (I've never gotten it, so haven't seen it first hand). There are procedures you can perform to remove dichroic fog -- a search will find them. I don't know how drastic these procedures are, and what effects they have on the film, though.

hi sean

i gotten "the fog"
it isn't pretty

you can remove it by bleaching it away with farmer's reducer.
but it is a PITA ... you are better off just getting a different developer it
will save you a lot of wasted time and maybe wasted film in the end...

good luck!

Thanks for the advice!

With T Max 100,

Just use HC 110 - 6 minutes @ 68 Deg.

Works like a champ, especially if your scanning.

Like, Bob, I use HC 110 for 6 1/4 minutes in a Jobo, works very well.
That is for old stock T max, I have not tried the new formula yet.
Bob, are you using that time on the new version as well as the old?

[IanMazursky]

I use Tmax dev (not rs) in my phototherm rotary tube 1:5 as recommended by the manufacturer.
I can process Tmax 100 sheets without any problems or dichroic fog.
Since they have the machine calibrated for Tmax dev 1:5 and times, i use it for all B&W films and it works great.

I also use HC110 dilution B in an open tray with a slosher; my normal development time is 8 1/2 minutes at 68 degrees.

I am using new stock Tmax100. The times are for that version.

I am using dil B, forgot to mention earlier.
