DX of Neopan 1600

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

I'm interested in trying some Fuji Neopan 1600 in my Leica Minilux. In order to compensage EV, I need to know the DX of this film.

Also, any thoughts about an appropriate ASA for shooting this film? Developing it (D-76 or Rodinal, for instance)?

Derr! Would that be 1600 ISO by any chance?

Pete, I know that 1600 seems obvious as a DX, but I recall that P3200 has "nominal" speed (Kodak's word) of 1000 . I've always taken that to mean that P3200 has a DX of 1000.

Since both P3200 and Neopan 1600 are both faster than the average film, it occurred to me that the 1600 was a marketing speed like the 3200 is.

I've used only manual cameras in the past and the issue of DX was an irrelevant issue for me, but now I have a Leica Minilux which does use the DX.

Sorry if my question seemed stupid to you, and maybe it is, as odds are that Fuji uses a DX of 1600.

Sorry Paul. I couldn't help taking the p*ss.

From fuji's curves, there is very little difference between Neopan1600 and Neopan400. In fact I couldn't see any difference in sensitivity. They both have toes that start at -3 lux seconds, and reach 1.5D at around the same exposure when developed in D76 to the same mean gamma.
The difference seems to be, basically, the label.

The DX coding is 1600. I shoot it at 1600, develop in Xtol 1:1. Contrast is fine for diffuse enlarger.

Kodak TMZ P3200 is DX coded for 3200. It's nominal ISO rating is 800/1000.

These films, like Ektachrome 1600 are DX coded to the EI that is on the box. To get this speed they must be push processed.

In fact, if you look at the box, it states the number as an EI not an ISO.

With some/many of these films, there are differences that make them more suitable for push processing. Mainly starting off lower in contrast, so that when pushed the contrast gain doesn' get out of control.

The real speed of Neopan 1600 is ASA 640.. So, you'll should try to develop it in the Microphen. Highly contrasty though..
