Hi,
I've just laoded some Neopan 1600 and have set the iso to around 1400.

Can anyone tell me what the optimum iso for this film is?

many thanks,
Richard

EI 1600 in Xtol 1:1 or even 1:2 works for me.

It's rumoured to be ISO 640 or thereabouts. When shooting lowlight with
high speed film, I often find that the full tonal range is not necessarily
one of my concerns.

and

are a couple of samples.

In almost all cases if you cut the ASA in half you
usually have the optimum film speed.Shoot it at 800
ASA and you are good to go.When you do that don't
develop it for all Saturday.I would always rate Tri-x
at 200 or Tri-x sheet film at 100.Francis Ford

Film speed all depends on your method of development and purpose of use.
Underexposure (higher EI) will result in loss of shadow detail.
Increased development can bring some of it back, but will at the same
time also increase contrast and highlight density as well as grain.

You may want to do some tests and see where the limits lie or where your
quality is best for your purpose. I recommend processing the film
yourself if you can or have a small custom lab (or a serious photo
hobbyist) do it. Just sending it out to get souped in over-replenished
stock D-76 will give disappointed results with blocked highlights and
poor acutance.

I have exposed Kodak TMZ at EI 25,000 (4 2/3 stops under its true rating
of 1200) and after careful but extended development still had very
usable images which were very grainy and flat looking because of lack of
real shadow detail. I guess EI of 100,000 (another 2 stops under) is
possible.

These high speed films such as Neopan and TMZ are designed to be
"pushed" at least 1 to 2 stops, to give you usable images at under low
light conditions. But they will give you better image quality if
slightly overexposed and DEcrease development, which is what you are
doing now (1/3 to 2/3 stop overexposed from 1600).

Hi,
I've just laoded some Neopan 1600 and have set the iso to around 1400.

Can anyone tell me what the optimum iso for this film is?

many thanks,
Richard

In the good ol' bad days, when we used b&w film in the paper I work 
for, I routinely shoot @1600 and souped in T-Max RS in deep tank,
the results where great, with almost no grain and good tone....

I've been using it at either 1600/3200 in HC-110 at 1:45 in a rotary processor. This has 
been for dance/theater where there has been very high contrast.

I've just shot some at 2400 and will process in Diafine. Curious to see how it turns out.

by shooting this film, you are already acknowledging a trade off
between absolute image quality and film speed. If the ultimate shadow
detail is needed, then shoot around 800. But if max usability is
needed, then shoot it around 1600. Of course if you need more speed at
the expense of shadow detail, then shoot it at 3200. I normally shoot
it around 1600 and push the development about half stop. 

When shooting at less than 1600, I don't reset the e.i. I just bias
the exposure measurements more towards the shadows. Maybe changing the
e.i. by 1/3 stop works for the Zone folks but it doesn't for my style.
Just too many variables how and where you meter and how you develop.
