Exposure for 160 ISO films

[point13]

I've been using Nikon Coolpix 995 digital camera to assist in the

metering of my Rolleiflex 2.8. I don't have the money to buy a hand-

held meter.

 

I've been using 100 ISO films so far. I'd just set the 995 to Apeture-

priority 100ISO, points the camera at different spots of the scene,

read off the exposure values and adjust the Rollei accordingly.

 

The questions are:

1. If I use NPS 160 or Portra 160, do I set the 995 to 100 ISO and -

0.7EV? (Note: Coolpix 995 can have exposure compensation from -2EV to

+2EV in 1/3 steps, 100-200-400-800 ISO)

 

2. What settings should I use for 320 ISO, 50 ISO & 25 ISO?

 

Any suggestions are greatly appreciated.

If used as an exposure meter I'd set it at 100 iso w/o

compensation. Overexposure is always better than

underexposure w/ print films. Some would argue that these 160

films are really more like 125 or 100 speed anyway. In other

words, error towards over-exposure: if the coolpix looks good (@

100), the NPS will too.

Ditto the above.

Lots of people do recommend over-exposing color print film, but (1) if you want to shoot slides, (2) if you need every bit of shutter speed and/or aperture you can get, (3) if you don't like the increased contrast overexposure can give, and/or (4) you just want to exposre correctly for whatever the reason:

 

For ISO 160 film, set the 995 to ISO 200 and +0.3 EV exposure compensation (or anything equivalent, such as ISO 100 and -0.7 EV exposure compensation).

 

For ISO 320 film, set the 995 to ISO 400 and +0.3 EV (or anything equivalent, such as ISO 200 and -0.7 EV).

 

For ISO 50 film, set the 995 to ISO 100 and +1.0 EV.

 

For ISO 25 film, set the 995 to ISO 100 and +2.0 EV.

 

Remember to try to get the 995 to meter something as close as possible to the frame the Rollei will shoot. (Does the 995 have a spot meter?) Good luck.

Thank you very much for all of your fast responses.

 

Dave, the 995 has spot metering which I've been using in tricky situation.

 

Yes, I am fully aware of the limitations of this method. Hopefully I'd have a incident/spotmeter one day.
