Auto mode & ISO400 - a question for the landscape guys
Out this afternoon for an hour with my D3100 "trying" a landscape or two. When in Auto mode the camera was giving an ISO reading of 400. If I want to try shooting at ISO100, I believe I will need to take it out of Auto and shoot in one of the manual modes. Should I use the Aperture mode and let the camera sort out the shutter speed? I only have kit lenses, using the 18-55mm where should I start with the aperture size? I seem to remember "the bigger the f/stop the longer the depth of field".
Thank you in advance.
