More E6 Questions: "Tom??"

Out of curiousity is there any or enough difference
between the Kodak and Fuji test test strips to buy one versus
the other? I've heard that Fuji requires a slightly longer first
developer bath and my initial testing confirms that. I use
Kodak chemistry, btw.

Also is a precision .1 analog versus a digital
..1 thermometer, better or the about the same?

A digital thermometer actually accurate to .1 degree costs more then you
can afford to pay. The way to get that type of accuracy is to buy a good
mercury thermometer and send it out to be calibrated at the temperatures
you will be using it at.

Honestly, I don't know if there is any significant difference
between Fuji's and Kodak's. Fuji's are likely on Fuji film,
but the whole point is to standardize so I wouldn't think
it should make that much difference. It may be Fuji strips
better reflect Fuji films.

The whole purpose of running control strips is to have a
standard and standardize the chemistry according to the
AIM values, and my local E6 lab guy doesn't think it would
result in any noticable difference in quality. OTOH I've
always used Kodak because I'm processing Kodak film. The
control strips are preexposed Ektachrome 64 film, but other
Kodak films and Fuji films are typically processed
commercially using these strips for chemistry monitoring.

Kodak is actually changing their strips to E100G film. I don't
know exactly what difference this makes other than Kodak
says it will better reflect the current "population" of E100
films being shot and processed. You are adjusting AIM values,
so as long as the control strips accurately adjust the
chemistry you have a process in control.

BTW, if you order and get the new E100 control strips vs
the 64 ones some color balance adjustments are supposed to
be different than they were with the old 64 strips, like
adjusting specific gravity of some solutions. I haven't
read about this yet but there's an update ("new control
strip information ")to the E6 manual on the web site.

Well, it's consistency of temperature that's important,
+/- 0.5F for the first developer. So, you need a thermometer
accurate to +/- 0.25 degrees. I just use the built in Jobo
digital and occasionally check solution temps with an
analog (kodak) thermometer I've checked against the Jobo
(i.e., if the Jobo is set to 100F and my analog reads 99.5,
I read the 99.5 as 100F.)

I've found the Jobo to be very reliable plus it's 0.25 +/-
accurate.

mercury thermometer and send it out to be calibrated at the temperatures

Like you said getting things consistant that's important. Have you had your
Kodak thermometer calibrated at a lab?

That accuracy is part of why a Jobo costs what it does. At the same time .25 is
a long way away from .1 in terms of price. I used to work at a calibration lab
and spent ten years as an instrumentation engineer. I've seen the price of probes
that were capable of .1 and a twenty dollar digital thermometer from Radio Shack
isn't going to do it!! :-)

No. And there's no need. It's consistently agreeable with
all my other themometers and accurate to within +/- 0.5F.
The precision does vary somewhat though.

B&H lists a Jobo analog thermometer with a .1 degree of accuracy for around 55 dollars.
