XTOL and film speed?
BJCarlton
some. I mixed up a five liter package and have been using it in a Jobo
processor, on TMY I've shot at ISO 400. I've been using the developer
full-strength. Otherwise, my standard developer has been TMax diluted
1:4. My impression so far (after about 5 runs over a couple months) is
that what was the right EI for the film in TMax developer is at least a
stop underexposed for the film in XTOL. I'm getting a fairly normal
contrast range, but very thin shadows. Since the contrast looks ok, I
don't think the film is underdeveloped; what it looks like is
underexposed. In any event, when I've lengthened the development time,
my contrast has gotten too high, without improvement in the shadows.
Using more developer (200 ml rather than 100 ml) per roll doesn't seem to
make a difference. Is this a standard experience for XTOL? I've been
reading elsewhere in this newsgroup about problems with the 1 liter size,
but that shouldn't apply here. OTOH, I've only mixed up the one batch.
I'd appreciate any insights.

All of the films I tested in XTOL, (usually 1:2) got a 1/3rd stop increase
in speed. Call Kodak pro support line and see what they suggest. After PMK I
think XTOL is the best developer around!

I have used Xtol 1+1 on sheet TMY. The film speed measures just right at ASA
400. I do not use the ASA rating on any films because I prefer more density
around Zone V, so I shoot at EI 200 to get a net Zone V density of 0.85 to
0.9. This results in a density from 0.2 to 0.3 at Zone I.
One thing that I noticed with TMY in Xtol 1+1 is that the film is straight
line down to Zone I and below. Thus, those people used to long toe films who
typically underexpose it and can still get some shadow detail, will find no
shadow detail at all if they underexpose TMY in Xtol 1+1. You have to be
more careful with exposure when using this combination. The problem is not
that the film is slower, the problem is that there is far less margin of
safety for underexposure.

speed-increasing developer, as I understand it.

real film speed, real increased shadow detail, it gives about 1/3 stop with PX
and TMY over D76 1:1. I think more real film speed can be obtained with Tmax
developer. With TX, film speed doesn't seem to change, as to Xtol or D76 1:1.
As to contrast, Xtol is definitely less contrasty than D76 and I find times
have to be adjusted accordingly.
As to sharpness, D76 is noticeabley better to me with PX & TX & TMX. TMY and
Xtol seemed to be a good combination.
As to overall look, I still prefer D76, or sometimes HC110 for increased edge
sharpness (and convenience).

I agree.
But in most cases it ends up being that Xtol will give you the stated speed and
no less and is not really going to increase the standard speed.
But T-max WILL get your 3200 with 3200 film that does not feel like a push.

Xtol often gives more speed with dilution than used straight.
The differences I've seen range from1/3 stop (Delta 100, HP5+) to a
full stop (Delta 3200). I'm using .10 DU above fb&f as the speed
point, with a "normal" CI.

Ah. Interesting. The volume limits of the Jobo make it a little
difficult to use XTOL diluted, unless I want to process very few rolls
at a time, in which case, why use the Jobo? I suppose what I should do
is to get another batch of XTOL and see if I repeat my experience (since
people don't seem to have observed the sort of results I've been
getting), and if I do get a repeat, then break out the inversion tank
and mess around with a dilute solution and hand processing. At some
point I may get tired of all this experimentation and decide to go back
to actually taking pictures (and using TMax, which has been pretty
reliable) . . .
Thanks to all for the comments so far.

exactly 100 and 400, which is 1/2 to 1/3 stop faster than anything else I've
tried. And the negs print beautifully.
