Nizo Pro + ext. light meter

[Liam Dale]

In the Nizo manual it says that using a handheld lightmeter will not give accurate results. I assme this is because of light loss in optics and the internal meter compensating for them to get a correct exposure. I think there are some times when it would be nice to use a handheld meter, or impractical to use the internal meter, so I was wondering if anyone knows how much to adjust a meter reading to give a proper exposure. Thanks.

I shoot Kodak Super 8 Color Negative.

I use a light meter.

I often take a reading and shoot Negative film one stop over.

 

Also, I have shot a slate with a color chart on it.

I shoot an exposure with the built in light meter.

Than I tak a light meter reading.

Typically I take detailed notes.

The I get the film developed and transferred to tape.

I supervise the transfer.

I can see the results.

 

 

It works for reversal Suer 8 film as well.

 

Also, I use the built in meter

and compare it to my hand held meter - A Spectra.

 

SUPER 8 ASA

Also, the notches on a Super 8 Cartridge set the ASA.

 

KODAK 500T

- Your camera may set that at 400ASA

 

KODAK 200T

- Your camera may set that at 160 ASA

 

Ektachrome 100D

I do not know what that set a camera's ASA

I use a light meter.

I over expose Super 8 Color Negative at least one stop.

The Kodak protocol for VISION 200 is to speed-notch the cartridge at ASA 160T and then use the notchless cartridge (the lack of a filter notch at the bottom) to key the camera to ASA 100. That makes it one-stop overexposed by design-- that's what Kodak recommends.

 

The Nizo will take away about a stop of light on its own that the meter would normally compensate for. So the best thing to do when metering externally is test and keep a log, always bracketing exposures to see what happens because much depends upon the accuracy of the meter readings even when dialing-in f/stops manually.

 

But roughly, figure about opening up an additional one-stop if you use an external meter. If you want to overexpose negative stock-- which is recommended-- then either rate the film at ASA 100 (or whatever) or open up the aperture a little more.
