ISO settings

[jomar]

The manual states that ISO settings 400 and faster ,images may appear coarse

Conversely is it right that at 100ISO the images is it's best, or is there no image difference from 100 throught to and including 200?

Looking forward to some feed back

My tests show that the digital ISO is roughly parrallel to film ISO - the lower the ISO, the higher the quality. But boy, it sure is nice when you need that extra f-stop or just a bit faster shutter speed to just click the dial and bump up the ISO instead of changing rolls of film (not to mention having to buy and store several different emulsions) It still lowers the quality- but far more convienent.

Lower ISO may force noisy multi-second exposures, when a higher ISO option may cut the exposure time and improve the image quality.

I have to run some tests with this!

Most of us don't have $4000 "Certify Calibrate Monitor...or
$4000...laser...dysub...printer....so we don't see what difference
from 100 ISO...or 200...I agree with Paul...about speed....go for...
S2 or digital advantage....
If your work have to deal with 1/3 F stop....$15000 digital back...
then....:confused:

You really can't see the difference between 100 and 200 ISO without a loupe and most of my clients don't carry one.

I have found the S2 to be far better than the S1 at the higher ISO's. To my eye the 1600 setting is less grainy than film.

I shoot no lower than 200 because I see no need to. I use 200 for portraits and 400 for flashed candids.... 800 and 1600 for available light work.
