Metering for light pollution at night

[Anton Bossenbroek]

Hi,

I am working on a project to capture the impact of light pollution in the Netherlands. I shoot with a Mamiya RZ67 and preferably Ektar film. In many areas in the Netherlands close to cities, there is always a residue of light at night. This residue makes it possible for the human eye to see decently but light meters such as the Sekonic L508 and the one in my Leica M7 fail at giving me a reading.

I'd like to shoot nature / still lives illuminated by light pollution.

- How could I best measure these scenes?
- To what extend do I need to take reciprocity failure / factor in film into account?
- I believe that Sekonic L508 has a minimum incident meter of -2 EV, are there meters with a lower minimum EV (I read a bit on the Gossen Luna-Pro but can't seem to find it's minimum EV spec)

Thanks for your help

For reciprocity, see the film data sheet. It usually addresses that concern.
