is there a linear correlation b/w stops of light, regardless of if you're adjusting ISO, f, shutter?
In other words, just talking about brightness (and not clarity, quality, sharpness)....
will each of the below brighten the image similarly (+ 2 stops of light)?
- ISO 100 to 400
- slowing shutter speed from 1/125 to 1/30
- opening aperture from F8 to F4
So taking an exposure at 1/60 f11 would be allowing the same amount of light on the sensor/film as 1/250 f5.6?
