Bellini E-6 Rotary Times?

[bags27]

I haven't used this in a couple of years, and have forgotten the times I've used. The instruction sheet is only for non-rotary.

It's a 6-stage developer, and the two times that matter most, I imagine, are First Developer (6' for first 4 films in non-rotary) and Color Developer (ditto times). I'm guessing around 5:15'in a rotary. Would that be about right? Would bleach also go from the recommended 6' for non-rotary to 5:15?

I'd be developing 2 rolls of 120 at a time, using 500 ml in the Patterson tank.

thanks!

Sounds too short. This is just a standard 6 bath chemistry. The "official" reference time is always 6:00, but in practice, slightly longer times are often needed for perfect results. Constant agitation is the norm in all color processes, and no time is needed to be shortened from official times because of rotary processing. Non-constant agitation may require extended times, but in E6, errors are most often due to too low temperature, or exhausted FD, than inadequate agitation. Bleach or fix time needs not to be adjusted, as everything except FD is done until completion in E6. I would suggest starting from 6:00, and probably extending from there. if needed. As you are talking about rotary developing in Paterson tank, the lack of temperature control may be an issue.

In fact, the critical step is only the first developer. The color developer is "to completion", so letting it run longer there won't be a problem. You can look at the times Jobo provides for their 6-bath chemistry - they, unlike Bellini, give times for rotary processing.
Overall, the process is standard, but there are slight differences in the timings. The issue is that some films require a bit more time in the first developer - Fuji films in particular. And Jobo chemistry is said to be manufactured by Fuji in Japan. That makes sense, and all these small differences start to fall into place.

Thanks to you both. That's really helpful.

I should add two qualifiers
1. The times Bellini cites for non-rotary is based on agitation every 30 seconds. So, rotary is a lot more agitation.
2. There is no cooling (well, there's a lot, but it's compensated for), because I'll be using my AGO, which has a tremendously accurate thermometer and adjusts time to falling temperatures. So, if I set it for (say) 6 minutes, it will never finish in just 6 minutes, as AGO will add time as temperature cools. But I do want to set the initial temperature as accurately as possible.

2 year old kit?

Ago drift method for temperature/time.

Sounds like a recipe for disaster.

It's all good, it's not like Fujichrome is unavailable or Ektachrome is 20 bucks a roll.

Oh Boy

I didn't say that the kit was 2 yrs old. I said that I haven't developed E-6 in two years. I wouldn't try an open 2 yr old kit either!

I've never tried AGO with E-6, but it has proved remarkably accurate both with B&W and C-41. So, yes, it is a new project for me, but, wow, does it work with other chemicals.
