Just watched this video. Not sure if already posted. I tried it and I like it. Why Auto ISO+Manual Mode Is the 'Best' Auto Exposure Mode
I usually choose between Aperture and Shutter priority modes. Used to shoot in manual and still do in certain circumstances but got tired of constantly rolling my thumb or finger to adjust while moving. I'm going to give this a try. Using my D3s I'll limit the ISO at 8000 and see what happens.
And that's the beauty of auto ISO - you set your aperture and shutter speed to create the look/feel you want while the camera adjusts ISO for the proper exposure.
It is not as if there are wide choices though.. ISO 100 to ISO 3200 is "only" five stops of range, so as always, our choice of shutter and aperture still depends on what works at the light level we find there. The only difference in this method is what varies...ISO, or shutter speed/aperture. My own notion is that choice of ISO value is more important than that.
It seems Auto ISO is favourite as a bit of grain is easier to fix than out of focus shot. However, in the March issue 43 of NPhoto, article LIGHTBOX, images from readers show nearly all images shot at ISO100. (One image was with a shutter speed of 20secs while the next was 0.4 secs but both at ISO100)I am still a beginner and still finding it difficult to decide among all the advice what to do. I tried setting the ISO to 100 (My D7000 only seems to want to set a minimum of ISO200) but my images came out underexposed. If ISO is set to 100 is it best to adjust the shuttter speed or aperture? I am trying to get sharp DOF in architecture/landscape so usually try f/8-F/22. Any assistance appreciated.

I find that using auto ISO almost always results in over-exposed shots. In very bright SoCal sunlight at 200, the camera still jumps to 400 ISO and the image is blown. I pull the speed back to 100 and it still shots at 350+. I drop auto ISO, reshoot at 200 and get a perfect image. Unless I am shooting in very unfavorable light or really need to push the speed, I have stopped using auto entirely.
Yes I try to keep the ISO as low as possible as recommended by many, especially in the NPhoto magazine. I am curious to know how to keep ISO at 100 whether using shutter speed of 20secs or much faster as in NPhoto March edition.
