nizo professional and tri-x??

[romeojesus]

A friend of mine has a nizo professional and wants
to shoot tri-x for the first time.

will the nizo expose the tri-x correctly?



here is what the camera has and does:

- the cam has a filter notch pin in the cartridge compartment!

- when pressing the pin (by hand or cartridge) the filter
gets out of the lens´axis (like its supposed to be)

- pressing the pin (by hand or cartridge) has no effect on the
light exposure meter.

- switching the bulb/sun dial from tungsten(bulb) to daylight(sun)
results in a 1/3 drop on the light exposure meter (as I expected it to do!)


I read that tri-x is notched at asa 250

the nizo has a wedge asa readout!

so will the tri-x be exposed like an asa 250 film when the filter
switch is on "bulb" and asa250 +1/3stop with filter switch on sun?

One question first:
Does this camera do b. when filter pin IS pressed?

so will the tri-x be exposed like an asa 250 film when the filter
switch is on "bulb" and asa250 +1/3stop with filter switch on sun?

-- With filter switch on SUN (filter removed anyway since filter pin is pressed), camera will expose triX at 160.

-- With filter switch on Bulb:
Depends on your answer to my question -
if you answer YES: camera will expose triX at 250.
if you answer NO: camera will expose triX at 160.

No, the opposite. If the Professional is like the rest of the "B" series... It uses a step wedge to read the notch, and maxes out at 160ASA. TriX (notched at 250ASA) will default to 160ASA on "bulb" setting, or 100ASA on "sun" setting. TriX is 160T/200D, so if you leave the camera set on tungston, you will be exact in tungston, or over 1/3rd in daylight. If you set it on daylight, you will be 1 stop over in daylight.

Ok! Did not know it maxed out at 160.
