Re: Can higher ISO give you more info about a low contrast scene.

You would. Although there can be times when slight underexposure is a plus in that it can help extend the high end range. But more than a stop is just wanking. Paul via phone On May 19, 2016, at 12:42 AM, Ken Waller wrote: >> Lightroom only allows a few stops of exposure compensation, and it

Re: Can higher ISO give you more info about a low contrast scene.

Lightroom only allows a few stops of exposure compensation, and it is very easy to exceed that range. Why wouldn't you try to get the exposure right in camera ? Kenneth Waller http://www.pentaxphotogallery.com/kennethwaller - Original Message - From: "Larry Colen" Subject: Re: Can h

Re: Can higher ISO give you more info about a low contrast scene.

I believe that there is an analog portion to the circuitry before it gets to the A/D converter. And this analog portion includes a programmable amplifier. So the A/D is always giving you all the bits, its just that at higher amplifications for higher ISO, the noise factor is much higher. On Wed

Howcome the same data are spread over a larger contrast range when you increase the ISO? Jostein Den 18.05.2016 20.37, skrev Larry Colen: I expect that the answer to this question is "Yes, but it makes no practical difference". Let's say a camera has a 12 bit D/A and at base ISO of 100 has 10

Can higher ISO give you more info about a low contrast scene.

I expect that the answer to this question is "Yes, but it makes no practical difference". Let's say a camera has a 12 bit D/A and at base ISO of 100 has 10 stops of dynamic range. In theory the chart would look something like this: DR ISO __ _ 10 100 09 200 08 400 0
