I prefer the Sekonic analog light light meters, they are very easy to use. Simply set the ASA dial to the film speed you are using, point the dome on the meter toward the light that will be illuminating your subject, then press the button. The needle will swing to an EV number (exposure value). Turn the other dial to line up the EV number with the high or normal setting (the meter comes with a slide which is inserted behind the dome in sunlight, when the slide is in, use the high table). Once the numbers are lined up, you can read the possible shutter speed/aperture combinations on the opposite side.
