Exposure is the same for digital as it was for film. Set ISO on your D7K, look at the scene and pick your F stop and Shutter speed. You'll get similar results as you did for film.
The way I do it is...
Set desired ISO, usually 100, adjust this as scene requires.
Chose Aperture, for desired DOF characteristics and adjust shutter for good exposure. Of course adjusting ISO is the third variable.
Or chose shutter speed, for desired movement control and adjust aperture for good exposure. ISO variable in play here as well.
Check the analog meter readout in lower right of viewfinder for good exposure. There is a "0" with "+" on one side and "-" on the other. Dashed lines appear on the "+" side indicating the degree of Overexposure or Underexposure if the dashed lines appear on the "-" side. No lines indicate proper exposure for a normal scene. Of course if the scene is a bride in white gown against a white background the proper exposure would require at least one stop overexposure, or more.
The analog meter will show up to two stops either side of the "0". I normally use the analog meter readout to introduce exposure compensation while metering a scene rather than the "exposure compensation" button because once you set the button for exposure compensation it remains for all succeeding shots until you remember to change it.
