ND Filters again
#1

I came across this statement in a NG...

"An ND filter is used to reduce the light reaching the film/sensor. With a film camera, it is helpful if your film is rated at too high an ISO for the scene, but with digital, adjusting the ISO of the sensor will do the same thing. "

Accurate? What do you think? I suppose if you're already shoot at ISO50 then you're out of luck... Big Grin

Maybe if we could dial in ISO 25, then this would be a little more true. Look at ISTD users though, 200 ISO is their minimum! :o

I guess its true if you can dial down that low but its not very accurate for a statement considering how most folks use their ND filters. They're great for getting a shallow DOF on a bright day.

I suppose there's the argument regarding sensor noise as well, but I guess if you're decreasing ISO then you're decreasing noise as well, which is usually seen as a good thing?

The Kodak has a "longer exposure" mode that combines a series of short exposures to create one longer-exposure image, at an effective ISO of 6.

Ironically, that camera is infamous for poor noise handling at higher ISOs.

On topic: I've tried taking slow exposures of moving water on sunny days, and even at f/22, ISO 100, with a polarizer, I couldn't get an exposure longer than 1/4s. A +2 or +4 ND filter would have come in very handy.
