One of the first questions I have is about the duty cycle in question here.&nbsp; I do not *reguarly* process RA-4 paper, and when I do, it is a "small volume" run.&nbsp; I don&#39;t think I&#39;ve ever produced more than the equivalent of thirty 8" x 10" prints in a single day.</td></tr></table><span class='postcolor'>
I don&#39;t either, so the question.. Its all low duty, sporatic processing whence my query about these chemistries.. as I mentioned 20l is twice a lot..

The second consideration *I* have is that my primary concern is quality, rather than economics.</td></tr></table><span class='postcolor'>
Of course... (and to have fun).. Lets face it.. If cheap was an issue it would all go to the drugstore chain where finished prints costs less than just my paper.

This discussion motivated me to visit Tetenal&#39;s web site.&nbsp; Glory&#33;&#33;&nbsp; Anyone who wonders if film/ chemical is "dead" should do the same -- they are putting a *bunch* of research into new chemicals, new materials, new processes.&nbsp; Interesting.

You spoke of "Tetenal&#39;s Ecoline BX-MR" chemistry.&nbsp; I couldn&#39;t find that anywhere, although that could easily be my fault.&nbsp; Their extensive caqtalog, in .pdf format, was not an easy one to navigate.

Its a newer Blix for medium throughtput. Did you have a look at the Ecoline family of RA-4 chemicals (Minilab):
http://www.tetenal.de/f_photo_mini_chemie_...ine_prod_uk.htm
The CD-SLR (developer) is 70 ml/m^2. They say for machines with high throughput but that&#39;s a nice low replentishment demand that seems right for slot processors.

Interesting chemicals here that I am NOT familar with.&nbsp; I note the trend to powder (pearl) forms of RA-4 chemistry (must have a very long shelf life) as well as a "rapid" form requiring 28 (&#33;&#33 seconds of normal developing time.</td></tr></table><span class='postcolor'>
That&#39;s the amateur market, resp. press (to the extent that its not nearly now 100% digital) stuff. The C-41 Phototabs, however, I really do like&#33;

Which all leads to: Where are your sources for the contemporay Tetenal chemicals?
- and where are you located?</td></tr></table><span class='postcolor'>
I am in Munich... and I guess I get stuff through various sources.

...I&#39;ll agree with that, but, mixing fresh each time MEANS a "new" batch, and although the "batch" to "batch" uniformity is very good ... there are inveitablly *slight* differences in color balance which - uh - irritate a perfectionist.&nbsp; "The same" also would neglect the effects of time in storage - even with measures to lengthen shelf life, this stuff DOES deteriorate- and, as near as I can tell, at a more or less "random" rate. </td></tr></table><span class='postcolor'>
The RA-4 process has, however, been designed to have a maintainable level of consistency... If not all the Kodak QC in the world won&#39;t mean anything other than that single test was OK but everything else was not.. same btw. with your "zeroing".. The commercial developers are designed to keep running for long periods of time and have been designed to "demand" a certain level of "polution".. that&#39;s why one uses starter for the initial bath (or one shot) should "old developer" not be available..

Intersting that you speak of "demand rates".&nbsp; What specific process do you use, and what equipment?</td></tr></table><span class='postcolor'>
I use all kinds of B&W and colour processes.. For film development its mainly between rotation in a Jobo Duolab (in the rotation part I use for C-1 the Tetenal Phototabs) or NOVA FP Dip and Dunk (the Press kits are good here).. For paper I&#39;m quite biased towards slot processors.. alongisde the Duolab, I have a few Jobo Primas and a 12x16" Nova Club (basically a TriMate with built-in washer)... for large prints (16x20" and 20x24") I tend to use hand-rotated drums (one shot). Since colour printing is limited pretty much to 8x10" and maybe a 12x16" it goes into the Duolab (so the 12x16" colour are done "one shot" via rotation)

Anyway ... I&#39;ll "re-ask" ... Where can I get this new Tetenal chemistry?
</td></tr></table><span class='postcolor'>
Alongside Tetenal.. and Calbe in Germany.. you may want to look at Fuji-Hunt and Champion..
