I have a Sony NEX-5N and I am trying to understand what is happening when I wind back the EV values.
Most of the modes have an option to change the EV except the Manual Mode.
So IN Program, Aperture Priority and Shutter Priority I can reduce the EV by +/-0.3 at a time through a simple click of a wheel.
But what is actually happening?
So lets say in Aperture Priority Mode - The shutter speed "floats around" based on what I am pointing at, as I reduce the EV the shutter speed increases. How does -0.3 EV translate to a decrease in shutter speed? I usually shoot in ISO100 all the time, however I note that when I set to ISO Auto and play with the EV, the same shot takes on a different ISO value, from ISO100 up to a maximum of ISO1600 and the shutter speed also moves but not nearly as much....
Thanks.
