New 400TX in HC-110

[bluecircle]

Newbie seeks advice for developing b&W film. Couldn't find any clear answer about the time for the new tri-x in HC-110(B). What seems clear is that kodak recommendation (3 3/4 minutes at 20 degrees C) is irrelevant and too short. Micheal Covington's page http://www.covingtoninnovations.com/hc110/ says most photographers recommend about 6 to 7 minutes.
Any idea about the standard time for 400TX in HC-110 (B) at 20 degrees C?

7 minutes at 68 degrees F (20 C) is right on target.

I heard that + or - 10% of your old time was right on. TomA has developed it with many developers so maybe research his posts. Kodak claims that they have done nothing to the 'new tmy' but make the grain sharper. So I would start with your old time/temp/agitation, and then go from there.

Be sure to let us know what you get as a t/t/a. I have a roll in a camera now but it won't be until next week before I develop.

I concour with George, I think that will be fine for a start. I will use 14-15 minutes with dilution H, but I am shooting at 250 ISO/EI.

Thanks charjohncarter & Geoge. I will use 7 minutes first.
I shoot 120 and latter may try 135. Will the development time be different between 135 and 120?

Try the Massive Dev Chart - I've found it to be a good source for starting times.

I have visited this website, but more confusion is added. Their recommendation is 4.5 to 6 minutes, longer than that of Kodak's recommendation, but shorter than others'.

I'd use Dilution H for 12 minutes with less agitations (5 per minute Versus 5 per 30 seconds) for a more forgiveable results. Experiment from there.

I second this. Either 12 minutes in HC-110 "H" or 10 minutes in XTOL.

The first time I used HC-110 with TX 400 I developed it for 6:30 (or 7 mins, I can't remember), and the negatives where very contrasty. The agitation I used was 10 seconds every minute. I now develop for 5:45 minutes, 10 seconds agitation every 90 seconds. I get less contrast and keep detail. Developing 6:30 made me lose a lot of detail. I scan my negs though, and scanners like "paler" negs. I add contrast with PS.

I'd start at 6 mins and agitate a 10 seconds every 90 seconds. HC-110 is very active and agitation is critical.

I've developed a roll in dil H, 11 mins 30 seconds, same agitatation of 10 secs every 90 secs. Liked the results, more detail, but also a lot more grain, so I decided to stay with dil B.

All this at 20ºC.

Search the forum in the film/developing section for a post by me (i've not written that much posts, so it'd be easy to find). I asked the same question.

Cheers.

When I was testing the new TMY-2 I used a roll of Tri X in each batch as a reference (I have pocessed 10 000's of Tri X so I know what they are supposed to look like). I found that 1:60 dilution (raw syrup 30ml/water 1800 ml) gave me the best result with TMY-2 at 11.5 min (30sec agitation initially and 10sec/minute after that). The "reference" roll of Tri X was a bit "dense" so I would recommend to cut a minute of this time, 10-10min 30 sec for a first try.
I have never bothered to figure out the HC 110 dilutions so I use straight syrup from the bottle and mix it with the required volume of water and "stir" it well.
As with any film/developing test - it depends on your style of shooting, the metering tecnique you are using etc. Do some tests first.

So far we have at 68f and with generally the same agitation: 5.5,7.0,7.5,6,6,6,5.75,5.75 minutes. So, so far the B dilution average is 6.2 minutes. Or for the dilution H crowd: 12.4 minutes. I guess Covington is the winner with 12 minutes for H or 6 minutes for B.

I'm confused ... the title of this thread is 400TX but everyone is talking about TMY-2. Huh???

For my first roll of TMY-2 I deducted 10% from the recommendation for the original TMY. Tri-X is a different story. In any event, I use Rodinal or Rodinal+XTOL.

I just ordered 100' roll of TMY-2 today!

 

[charjohncarter]

Don't be confused, I miss read to film code. Sorry.

Kodak have always been confusing with labels. The new "improved" TMax is still labeled 400 TMY on the box despite it being apparently called TMY-2. 😕
