I bought some of this film awhile ago on a whim and have not shot it. 6 ISO and the Kodak recommended developer is D-96. I have the chemicals, and formula, to make the developer but can't find a recommended time for development. Anybody has any suggestions?

I'm shooting it right now and will develop it @ 4 minutes/75 degrees in Cinestill DF96 Monobath.
I'll be posting results in the DF96 thread.

I've used a variety of developers on this film -- Rodinal (semi stand), HC-110, Diafine, and most recently Adox FX-39. I had hoped the Diafine would enhance the speed, and I shot it at ISO 25 and 12, but I only got so-so results (at either 3+3 or 4+4). And that's what this film requires -- just a lot of trial and error because they're few published times. Very good results at ISO 6 in FX-39 (1:9 for 8 min), good results with Rodinal (stand) and Diafine (at iso 6, 3+3), and OK results with HC-110. I can tell HC-110 will work, I just need to lengthen the development time. Anyway, I've only shot 8-10 or so rolls, and my Flickr page has some of the results. Never used D96. I would start with 7-8 min and see what you get. Good luck. Let us know your results. I still have a dozen to shoot up from a bulk roll.

Just developed a roll of Eastman 5234 in DF96. It turned the developer green!! Brand new batch too, hope it is not ruined.
Also only got 33 exposures on what was meant to be a 36exp roll!
FYI came out great - 4 minutes @75.

Should just be dye washing out. A pre-wet can reduce that if you like. You should see the stuff that comes out in the pre-wet with C41, and the developer still gets pretty colorful but works fine (I replenish).

The Kodak data sheet says that at 21C/70F, 4 min in D96 gives a gamma of 0.47 and 8 min gives 0.68. These are very low and high contrast for photographic applications. I’d pick somewhere in the middle but you will probably need to refine your method. They also say 12 min gives a gamma of 0.76 but that’s not very useful for still photography.
These duplicating films are very thin and contrast changes quickly. Unfortunately they don’t respond to dilute developers very well, so the only real way to get your negatives right is to tune exposure and development time.

Thanks? Where did you find that? The only Kodak Data Sheet I could find was July 2015 • H-1-5234t. On the processing information it gives no time but a footnote says " Develop to recommended control gamma". Big help! It does give the density/gamma curves but it's for tungsten light source so I wasn't sure how correct that would be. Plus I'm not that sure how to interpret the curves.

If you look at H-1-5234t there is a graph on p2 'characteristic curves' that has the time, temperature, developer and gamma. It's not presented in a table like it is for photographic films because for cine film the curve is what is most important.

I use Ilford paper developer 1:20, 4 mins. Works fine for my work.

I've looked (and amstill looking) at those curves and I can't quite my head around it. But it looks like maybe 6 minutes would be a good place to start. Have to finish a 36 exp. roll (got sidelined by hurricane) and mix up some D-96 to start testing. I'll cut the 36 exp into 4 separate spools to est at various times. I have other formulas for low contrast developer but D-96 was recommended and is a simple mix.
