Johnny, Thanks for the fredparker site. Wonderful information. I got my
question a little mixxed up and my former exposure information and queries
were from Buckskin Gulch. It's quite a bit darker in there because the
walls of the slots are sometimes 250 feet high.
I don't think that setting the camera at a higher ISO will change the
ability of any camera to set exposures at lower light levels. It's just a
limitation of the exposure system to a certain EV level. The only thing that
will really change this is to get a lens with a larger aperture.
And I love live view for focusing in the dark. I was doing some 2 second/f8
exposures at sunrise in the Alabama Hills, aimed at the rocks on the
horizon, put on the live view x10 and it focused wonderfully.
