Ok, so I was looking at results from yesterday's early morning shoot (separate thread), and realized (I'm sometimes very thick-skulled) that if noise is from ISO, probably lower ISO would be lower noise, and that's ok because I know I can increase shutter speed, and use a tripod with remote release.
So this morning I did a test, and with the blinds closed in the living room so only minimal light was coming in, put the camera on the tripod. Started with ISO 6400, aperture 4, relatively fast shutter speed for proper exposure. Shot at every ISO setting all the way down to 100, decreasing shutter speed as I went. Once I got to 100 ISO, I then decreased the aperture (increased the setting number).
I immediately took the 20 or so photos I ended up with and look at them one by one.
Now I see for myself the difference that a slow shutter with low ISO can make for high noise. Won't work in wind or with moving subjects, of course. But for what I needed to learn, this was a perfect experiment.
I suppose that sometimes I just have to experiment for these things to "click" rather than be all book-read.
Next weekend I'm going back to the same location to do another photo shoot in the sunrise, and see what I can get when I'm not too lazy to use the tripod and proper settings. Probably five billion percent increase in satisfaction with the photos I get for the little effort it takes to haul around the tripod.
Thanks for listening,
Kevin
