Sorry if this this already said.If I open up 4 stops, then is it ƒ2.8 or ƒ4?
Or 1/250 or 1/500?
Trying to shoot ISO 1.6 film
The guide says that if you can't set at ISO 1.6, then set to ASA 25 and "open up 4 stops" - Would this be shutter speed stops or aperture stops?
You can tell your camera to overexpose by 4 stops if it goes that high. Easy as pie.
