I'm running my first roll of film through my new Holga WPC. I went for Velvia 100, which the wisdom of Google suggests is good for long exposures.
So how do I work out metering? My exposure meter only goes up to f32 but the WPC is f135. So there's about 4 and a bit stops difference? f32 -> f45 -> f63 -> f87 -> f122
Is that all I need to do, then? Work out the f32 value using the light meter and slow the shutter by a bit over 4 stops?
Thing is, though... I was out earlier in sunny but not really bright conditions, and the meter was reading 1/8s for f32 and ISO 100. So 4 stops slower is 2 seconds - that doesn't sound long enough. The guide on the back of the Holga says 7-9 seconds for sunny weather.
Help :shrug:
