TMY in Tmax-RS on Jobo Help!!

[Donsta]

I currently shoot TMX in all formats with the zone system and my tested times and EI in Tmax RS on a Jobo. I am very satisfied with my results and the process, but ocassionally I yearn for some speed (I'm shooting the TMX at 64 for N). I'm not keen to go through days of testing for infrequent use: has anyone done the homework? If so, would you be willing to share your times, EI etc. ?

What format are you shooting? 35mm, 120, and 4x5 have different film bases which will invariably effect EI and development time. I tested 35mm and 120 and they are pretty close, with 120 requiring a bit more time.

TMY:
EI: 250, Tmax RS 1:9 @ 75F for 8.5 - 9 min. 240ml 1500 series tank.

I shoot mostly 120 and 4X5 (a little 8X10). With TMX I find no difference between roll and sheet films. Obviously I will do a little testing, but it would be great tp have a sensible starting point.

By the way, this question prompted a member, Michael Scarpitti, to send me this PM:

" What?

What are you talking about?

B&W should NEVER be processed in a rotary processor. NEVER.

The contrast gets too high and the speed too low.

Hand-processing is the ONLY acceptable method for 35mm work.

Also, the zs is nothing but a fraud.

TMY is horrible for outdoor work.

In other words, everything you're doing is wrong."

Ignore him; he seems to popup occasionally to criticize and question other people's intelligence.

Yeah, throw everything you know about shutter and aperture out the window too.. God some people have nothing better to do with their time.

I actually got a response from MS thanking me, perhaps tongue-in-cheek I suppose, for my post. I didn't have the heart to tell him that I am planning on buying a Jobo CPP-2 so I can process Efke at home ... uh oh, I think I just told him. I guess it it time to blow the dust off my old "Zone System for All Formats" book.

BTW, are you using the Expert Drums? I would like to find out more about them.

 

[Donsta]

I use the expert drums and can highly recommend them. I have never seen any indication of uneven agitation. They are expensive, but work just fine and produce perfect results. I went for a mechanized process so I could be sure to have an absolutely consistent process. The fact that temperature control is also perfect helps this cause. I have been using a Jobo for many years now and I am extremely impressed with the product.

Great. I used to have a Jobo CPE - which I owned for many years - but it got stolen a few years ago. I was considering replacing it with another CPE, but once I read about the Expert Tanks I started considering the CPP-2 instead; even though it is much more expensive. The plan is to use it for developing B&W as well as E6 (if I can get the chemicals here).

I actually prefer the 2500 tanks for E6 - I find that the expert drums tend to make E6 films curl quite a bit - I don't have any problems with B&W films though.

Thanks, I'll remember that. I actually still have some 2500 tanks, as well as the 4x5 reels and loader.
