self-developed tri-x

[anitasanger]

i have shot, developed and printed my own tri-x 400 b&w 35mm film for years now. i have a makeshift darkroom in an old cedar closet. considering i could find a super 8 reel system and tank, couldn't i theoretically develop super 8 trix with the same chemicals, times and formulas that i use for my 35mm still trix? considering it is 400 speed and exposed at the correct exposure? if so, i'm pretty excited about doing it!

7266 is 200 ASA. Other than that, it should work. As long as it is that new d-96 chemistry (or whatever the new one is)

Use search at the top of the page. Plenty of discussion on the topic. Or use google for this forum. Gives better chances of finding something.

I may be wrong but I have a hunch that if you develope the film the same way that you've done your 35mm negs for years you'll end up with the same result....A NEGATIVE !

I've been toying with the same idea since like you I've been playing around in darkrooms for years.

I think I saw somewhere on the Internet that it has to be bleached and exposed to light and developed in a 2nd different developer or something like that.

Yeah, found the site.

Actually at KODAK not surprisingly. Look under "Film Chemicals Lab Guide"

...yeah, you will find lots of discussions on this in the archives. I was involved in a project last year and we used this method:

Tri-x and Plus-X developed as a negative in Kodak D76. Then transfered by CinePost in Atlanta. I have used both the G3 and Lomo processing tanks and prefer the LOMO. Make sure you get the LOMO that can handle two 50' rolls at a time.

Here is a roll from our project:

You might find this interesting -- I translated it for this forum into english

Inexpensive Super 8 home processing tank made from PVC drain pipes

Very nice, thank you.

Now find a tube which will fit close but not tight in a JOBO 3062, 3063 or even 2540 and fabricate the windings onto that tube. That way you could put the S8 film in such a drum and process it on a JOBO ATL machine. Automatic!

[anitasanger]

awesome links! thank you very much.

Sure, Jobo ATL might work well -- but its a lot more expensive then rolling the tube on the table; and probably less fun ;-)

Was wondering if it could be done someway, and something similar to what's described on that website would probably do. I started working as an industrial photographer this week, and I was really surprised to see we're developing our films inside the studio - we have two ATLs and I'm supposed to develop all the films. I'm not sure we can do processings other than E6, didn't ask yet, so I'm planning to try some 64t first.

Have to find a drum that fits a long pipe, and the only feasible solution seems to be using the drum for three 120 rolls, because it' almost 20cm long. the other drums are only for 10x12 and 13x18, and there's no way (I guess) to use them for super8

Interesting link, anyway, good start for some experimenting.

Your 120 rolls tank will definietly be too small. One S8 roll is 15m, even if the diameter of your core would be 15 cm (in a 18 cm diameter drum), one winding would be 15x3.14=47cm only, you would need 1500/47=32 windings, so a 35 cm long drum.

Not sure if such exists

Reversing bw stock is pretty simple BTW, so you should be able to do that with your machine.
And glad you like my homepage :o

Sure, and the diameter is probably less than 18cm (have to check next week), but I thought it might be possible to fit two pipes in the tank.

Other option is to buy a new tank myself, checked B&H and there are some huge jobo tanks for the ATL.

The JOBO 3062 and JOBO 3063 are the biggest. You will find them easily on eBay. However, these fit only the big ATLs and not the 800, 1000 or 1500.

The 3063 can easily hold a rack which can take 2 S8 films. The main points in an ATL are: it is automatic, temperature controlled and it uses small quatities of chemicals... The trick is not to fill half way but much more like a paperdrum

Should you aspire bucket processing like effects you could unwind the the film into a 2520 test drum or another small type. I think you should fill this like when using it for films in reels.

we have an ATL 2 and an ATL 2000 - looks like there's room enough for a 24" tank. Will the 3062-3063 fit on these machines?

thanks
