    trying to understand the simple difference between the two, I found this short article

    Digital camera exposure compensation


    my camera has EV settings that I can change, but I don't see anytype of EC settings...Am I understanding this wrong? Or does some cameras have both, and mine does not?

    thanks for your input

    If by EC you mean "Exposure Compensation'... they are essentailly one in the same...

    If you want to adjust the Exposure Compensation, you change the Exposure Value.

    No, they are not the same. Saying they are is like saying "miles" are the same as an "automobile".

    EV, like miles, is a unit of measure. The Exposure Compensation control (EC) is a device to change they exposure and is calibrated in EV units just as an automobile is a device for changing position and its measuring device (odometer) is calibrated in miles.

    The EC control on a camera adjusts the metering system. When set to a non-zero value it causes the camera to shoot using an exposure that differs from the meter's opinion by the set value. The conventional units for calibrating the EC control are EV (Exposure Value) units.
