1) First, make sure you know the ISO of the film or paper you're using.
2) Set the ISO value into your light meter.
3) Meter your scene and reference the exposure time for the largest f-stop that your meter will read.
4) Use the following formula to convert the exposure time for your camera's f-stop value:
(f/R)^2 x Tm = Tc
f=Your camera's f-stop
R=the reference f-stop used on your light meter
Tm= The uncorrected exposure time recommended by your light meter
Tc= The corrected exposure time you'll actually use
Thank you Joe! I'll give this a try when I get the camera. It was shipped on Wednesday from Poland so I'm expecting it to arrive to Finland around Tue/Wed next week.
