The rule is simple.
- Set your shutter speed to the inverse of your film speed.
|100||1/100 (or 1/125)|
|200||1/200 (or 1/250)|
|400||1/400 (or 1/500)|
- Pick your aperture according to these conditions.
|Aperture||Lighting Conditions||Shadow Detail|
|f/22||Snow/Sand||Dark with sharp edges|
|f/11||Slight Overcast||Soft around edges|
|f/5.6||Heavy Overcast||No shadows|
|f/4||Open Shade/Sunset||No shadows|
I’ve shot a couple of rolls of film in the Paxette now, with good success when it comes to exposure. Unfortunately the Paxette has a fixed shutter speed of 1/40 so it’s more a case of choosing the ISO to match the shutter. Fortunately Ilford produce a film with ISO50.
For a laugh, I also spent a day practising with my DSLR in full manual, exposing with the Sunny 16 rule. It worked!
I think all photographers should be aware of it, because it’s extremely useful. Give it a go!
