Xtol + Tech Pan @ 40 - 80 for pictorial applic.
Christer Almqvist
Technical Pan at EIs of between 4 and 10 if you develop in Xtol (and at EIs of
between 16 and 25 if you develop in Technidol liquid).
Besides the high price (four times the price of normal 35mm films), another
main disadvantage of Technical Pan is the low EIs. I could not bring down the
price, but I managed to up the EI. Rumours say that is difficult to develop
Technical Pal, but I have not found this to be true.
Tetenal's Neofin Doku (which is difficult to get in the US) will let you use
an EI of 80 or more if you develop one film for five minutes using continuous
agitation (7.5 minutes for the second film or for two films developed
simultaneously using the contents of one of the small bottles). This developer
will give excellent results for most types of pictorial applications.
You can also also get very good results if you work with an EI of 40 for
portraits and develop in Xtol 1+3 for 12 minutes agitating for 30 seconds
initially and then 10 seconds every minute. There are however applications
where Xtol diluted 1+3 will not give results that are satisfactory, e.g.
still life of cutlery and glass.
If you want to shoot still life of cutlery and glass you can shoot at EI 80
and develop for 14 minutes in Xtol 1+1. The results are almost as goods as
with Neofin Docu. Xtol diluted this way is not suitable for portraits unless
... you want to copy the famous picture of the well built mechanic with
standing in the garage door with a big tyre.
The negatives developed as above will enlarge well on grade 0 paper using a
diffuser type enlarger That may be a bit extreme, but I do not see it as a
problem as long as the final print shows good gradation. And with Tech Pan,
grain and sharpness are non plus ultra.

Actually I haven't found any way to "boost" the
actual EI of TP and I don't expect . Also any attempt to
"push" a little extra speed (above EI 25) resulted in higher
contrast and grainier images. At that rate I might as well
use T-Max 100 or Ilfords Pan F+ which are both faster and
will feature finer grain when processed for contrast indexes
of .65 and printed on my D-5 XL.

The tests are still preliminary but the increase in shadow detail with the
water bath technique seems very promising. What I'm hoping to do is under
develope the techpan, therefore lowering the contrast and reducing the extreme
desnty f the highlights, but techpan tends to lose it's shadow detail if
underprocessed, so I'm hoping that the combo of under developement and water
bath might render a really good tonal range and good shadow detail.
The probelm with water bath is that it takes about 45 minutes to just dev the
roll. I'll let you know how things progress.
